Cooler Master V10 CPU Cooler

Cooler Master V10 CPU Cooler

Introduction

If one things for sure, there truly seems to be a never-ending supply of new and innovative CPU coolers at our perusal. Just when you think they've thought of everything, something completely different lands on my desk, just waiting to be punished. Luckily, the excitement of pushing the latest releases to the brink of meltdown has yet to leave me.
I have quite often pondered just how heat removal capacity could be harnessed with air-cooling designs. Cooler Master has established a strong and solid presence in the aftermarket cooling world, and having been around for 10+ years, it is not hard to see their highly-focused efforts in providing strong and dependable cooling solutions. From heat sinks and fans to full-featured PC towers, they have something for everyone.
On my desk today is the V10 CPU cooler. With 10 heat pipes, dual fans and a variable TEC plate (Thermoelectric cooling) there is no doubt as to the purpose of this monster: rip as much heat as possible out of your processor. This is Cooler Master's first TEC hybrid design and they have taken a different approach by pairing up this potent technology with air cooling.

Closer Look

Considering that I was already well-aware of the specifications of the V10, I must admit that the sheer size of it still makes my eyes bulge. Once out of the box, I got my first glimpse of the beast in all its glory. The large full cover shroud grabs your attention with its chrome detailing. This thing is a monster.
Flipping it around we get a glimpse of the TEC controller and the fan wiring. I really appreciated the fact that the fans are wired together keeping the clutter down to a single 4-pin PWM-capable connector which can find its home directly on your motherboard header. This angle also gives you a better look at the TEC.
Looking down at the top exposes the down-blowing fan which not only blows across 4 of the large heat pipes but also your motherboard. Most if not all motherboard designs place the memory squarely in this area as well as the CPU power circuitry, so the double-duty nature is a nice touch. The fan grill is solid and will protect anything that may try to come in contact with the fan.
Rolling it onto its side we now see the belly of the beast. There is another large surface area section with 2 more heat pipes protruding upwards. A second 120mm fan is ready and waiting to blow across this area and out towards the back of your case. Four of these pipes terminate in the bottom layer of the TEC sandwich. I appreciate the attention to detail and the very good build quality exhibited here.
By adjusting the angle in this next photo you get a better sense of how the heat pipes are oriented. The bends are quite smooth and almost ripple free. The TEC plate gets its power from the control module that resides directly over the CPU contact area.
Moving closer to the front allows us to take a better look at the heart of the V10. The pipes are laminated to the plate on the lower half of the TEC.
Peeling off the protective plastic from the mounting area allows us to check it for flatness and finish. I checked flatness with a metal ruler and found it to be nearly perfect and the finish itself was quite smooth. While it is not a mirror finish by any means I could not feel any imperfections at all. The protective layer did its job very well.
Included hardware was extensive and will allow use on virtually any platform available. The instruction sheets were very thorough. While it would have been nice to get a bit more, you get enough thermal paste to perform a single install.
So with that said, let's see how this beast will fit into our testing machine, and also check out some results, followed by my final thoughts.

CoolIT ECO A.L.C. Liquid CPU Cooler


Introduction

The search for the perfect cooling solution for that new PC you're building never seems to end. Every manufacturer vouches to have the most efficient, quietest and cheapest solution available, and if we merely took their word for it, there would be no need to shop around.
As of late, advertising has reached an unprecedented level with the overwhelming popularity of the Internet and people's ability to research a product down to its very last detail. Some days I almost (and I do mean almost) wish that we were not bombarded with so much information as it does lead to sensory overload causing even the simplest decision to be nearly impossible to make!
Whether you're choosing air or water cooling, there is one simple fact that always comes to the head of the pack: simplicity is a MUST. No one wants to go to be forced to go to engineering school to learn the proper way to install a CPU cooler and they want it to just work straight out of the box with little tinkering. While the enthusiast market is growing day by day with people becoming ever braver to try more difficult installs, there is still only a very small segment of the market willing to put in the effort, and rightfully so.
CoolIT has specialized in PC cooling and has products to cover pretty much any area of the current market. From TEC-based monsters to the venerable all-in-one water cooling solution, CoolIT has been very busy in doing its homework and listening to its customers to make sure it's in tune with what is expected in current products as well as future releases. Having tested its products before I can attest to the fact they do build quality stuff with a strong attention to detail and performance.
Today we get a look at the ECO A.L.C (Advanced Liquid Cooling). There was a time no so long ago that all-in-one solutions were scoffed at without a thought and were nearly ineffective and costly as well. Thankfully, that day is in the past and with releases such as the CoolIT Domino and the very successful Corsair H50 people are forced to take a long hard look at these types of coolers. I have said it many times in the past, water cooling is nearly unsurpassed with its ability to remove tremendous amounts of heat load without falling victim to heat soak. Multi-core processors have the uncanny ability to push their cooling solutions to their limits while overclocking pushes many past the point of failure.
With a simple design, CoolIT is once again setting the stage for another budget water vs. high-end air cooling battle. While we are not directly comparing the ECO to any air solution, we will give you all the facts you need to make the decision as to which way you should go for your next build. When the dust settles, I feel you just may be surprised at the results, so with no further ado, let's get the ECO A.L.C. out of its box and onto a CPU and let parts do the talking.


Closer Look

Shipped in a rather plain and colorless black and white box, the ECO is well packaged and protected in a solid foam clamshell. Just for giggles I even sat down on the box and it held all 200lbs of my weight without feeling like calamity was imminent. Once out of the packaging and onto the table we see that we are given a simple yet elegant cooling solution. The quality is readily apparent and without a doubt you can see the engineers did their homework.
Focusing in on the pump/cup block once again shows off the clean lines and styling. The shroud has the CoolIT logo and part name printed on it and you can also see the simple yet effective thumbscrews used to attach it to the CPU socket. Should you prefer it, the screws are also able to be fastened using a Philips style screw driver.
The radiator is compact and has a solid feel. There is no flex in the metal and the finish is excellent. All of the connections are firm with no play so there is no worry the hoses could come loose once installed inside your case. To me, this is the main appeal of a pre-filled water cooling solution as most people are far too afraid of leaks when contemplating a custom-built water cooling loop.
While we are not given the exact specs of the included fan, I was happy to see it was of the 4-pin PWM style, meaning it will be able to be finely controlled by the motherboard's BIOS as nearly all current motherboards have very effective fan control features built in. This will further enhance the effectiveness while helping maintain quiet levels, should that be within the desired operating parameters.
The base of the High Performance FHE (Fluid Heat Exchanger) has micro channels that help maximize cooling potential. It also sports pre-applied thermal paste so you can skip the often messy step of applying it yourself. Also take note of the simple multi-mount tabs. All you have to do is pull up on the thumbscrew to slide the tabs into the position needed for your socket. I think this innovative design feature is top-notch and far better than shipping multiple brackets for the 3 main Intel sockets.
Here we see the rest of the included hardware which comprises the many back plates for the 3 Intel sockets as well as the required mounting tabs for AMD sockets and also the respective back plate. Four screws and a simple installation guide round out the included parts.
I cannot emphasize just how much the simplicity of this design impresses me. While I have built many custom water loops for my personal PC over the years, it was still a daunting task which took days to do properly. This sleek design is sure to be a big hit with the mass market as long as it works as well as it looks.
Now that we have shown you the goods, it's time to get it installed and see just what it's made of.

ATI Radeon HD 5970 2G Extreme

ATI Radeon HD 5970 Review: Dual-GPU Graphics


ATI revealed its last generation Radeon 5000 graphics family last September, when we got the chance to review the ATI Radeon HD 5870, and what a treat that was.
In a few tests the single-GPU Radeon HD 5870 was able to outgun the mighty GeForce GTX 295, while in most it managed to match or improve upon the Radeon HD 4870 X2. As you are likely aware, both of these products carry dual GPUs, which bring a number of implications, not to mention bigger price tags.
Looking forward we knew Nvidia would have no immediate response to the new Radeons, while on the other hand ATI was not done unleashing its full series of products. Subsequently we looked at two more products that were meant to underperform the flagship HD 5870: the slightly cut down Radeon HD 5850 and the mainstream aimed HD 5770.



From left to right: Radeon HD 5770, HD 5850, HD 5870, and HD 5970.
But as we discussed in our preliminary Radeon 5870 review, on the horizon was also a follow-up to the Radeon HD 4870 X2, code-named "Hemlock XT", which in essence would put together a pair of Radeon HD 5870 GPUs on a single PCB.
Today AMD is officially unveiling the Hemlock as the new ATI Radeon HD 5970, hoping to expand its current dominance in single-GPU performance with the fastest single-slot graphics card on the market -- a title that until today was reserved for Nvidia's dual-GPU GeForce GTX 295.
The Radeon HD 5970 looks to be well suited for the job. The GPUs used in this card use exactly the same configuration found on the Radeon HD 5870, while core and memory frequencies match those of the Radeon HD 5850. This provides the HD 5970 with an unmatched memory bandwidth of 256GB/s.
All this horsepower will come at a hefty price, as AMD expects to charge as much as $600 for it. This is a bit hard to swallow, but all things considered it's about where we expected it to stand among the rest of high-end graphics offerings.



Full exposure: A "naked" Radeon HD 5970 graphics card.
The $400 Radeon HD 5870 is still sold out virtually everywhere due to extreme shortages. The Radeon HD 5850 version still costs $300, meaning that a pair of them would cost the same amount as a single Radeon HD 5970, and we do not expect the performance to be nearly as good. On the other side of the equation, Nvidia's top performer, the GeForce GTX 295 is selling for around $500.
As we see it, only extreme users looking for the best possible gaming experience - or the bragging rights attached to the label - will find the Radeon HD 5970 to make complete sense.
Knowing this is the 5970's intended market, AMD has stamped a big "unlocked" label over the card in our press kit. Perhaps more marketing buzz than actual functionality, the Radeon HD 5970 allows you to jack core and memory frequencies as high as you like -- or at least as high as they will go without compromising stability. This in itself is far from exciting news as there's been software available to do just that for ages.
The most interesting part should come from the ability to adjust voltages and thus increase the card's overclocking room, something we'll be checking in detail next.
Radeon HD 5970: The Card In Detail
The Radeon HD 5970 is a truly massive graphics card, even for a high-end dual-GPU product. Its dimensions whale anything previously seen, measuring in at 30cm long and weighing a little over 1kg.
Our review sample hung a total of 6cm off the edge of our Asus P6T Deluxe motherboard used for testing.









Cooling the Hemlock XT GPUs is a large aluminum heatsink made up of 36 fins. Measuring 16cm long, 7cm wide, and 2.5cm tall, it is slightly larger than that used in the Radeon HD 5870. Connected to the base of this heatsink is a massive copper plate which helps improve efficiency, while a 75x20mm blower fan draws air in from within the case and pushes it out through the rear of the graphics card.
For the most part this fan operates very quietly, helped by the impressively low 42 watt idle consumption of the Radeon HD 5970. When gaming, the fan will inevitably spin up as the card can consume up to 294 watts under load, but even with the increased thermal stress the 5970 does not scream at intolerable levels.



The heatsink and fan have been enclosed within a custom built housing that conceals the entire graphics card, which is the same design used with the Radeon HD 5870. This setup helps protect the card very well; Nvidia has been using similar enclosures for some time with their most prized graphics cards, such as the GTX 295.



Removing the heatsink exposes the two GPUs, GDDR5 memory chips, and a few other critical components.
With the heatsink off the Radeon HD 5970 looks almost identical to the Radeon HD 4870 X2, though it is noticeably longer.



Key changes involve the new GDDR5 memory, improved power circuitry, and an updated 2.0 PEX bridge from PLX Technologies, used to link the GPUs together. All this hardware is cooled via the large heatsink that covers the majority of the card’s 30cm long PCB.
GDDR5 memory works at an ever more impressive frequency (1.0GHz x 4) on this particular model, which features a total capacity of 2GB. The core configuration of the Radeon HD 5970 doubles everything in the 4870 X2 with 1600 (320x5) SPUs, 80 TAUs (Texture Address Units), and 32 ROPs (Rasterization Operator Units).



AMD’s reference card came equipped with Hynix ICs (H5GQ1H24AFR-T2C parts). These GDDR5 modules are rated for 1.25GHz operation, so we expect to push them beyond the stock 1.0GHz configuration without hassle.



In order to feed the graphics card enough power, a pair of PCI Express power connectors are used (6-pin and 8-pin sockets). This is the same configuration used by previous dual-GPU graphics cards such as the GeForce 9800 GX2 and Radeon HD 4870 X2, so current high-end power supplies should cater for this new graphics card.



The Radeon HD 5970 naturally supports CrossfireX technology, and therefore in the standard position we find a single connector for bridging two cards together.
The only other connectors can be found on the I/O panel. Our sample featured two dual-DVI connectors and a Mini Display Port connection. Just like the Radeon HD 5870, the 5970 can support a maximum resolution of 2560x1600 on not one but rather three monitors.

Already the Radeon HD 5970 is starting to look impressive. With a 3Dmark score of 9238pts at 2560x1600, it has not only set a new record for single PCB graphics cards, but also managed to outperform both the GeForce GTX 295 and Radeon HD 5870 by comfortable margins of 37% and 48% respectively.
Furthermore the previous generation AMD flagship card, the Radeon HD 4870 X2, was blown away by a 62% margin. We're eager to see how this numbers translate into real-world gaming performance.


Benchmarks: Unreal Tournament 3, Batman Arkham Asylum









While the Radeon HD 4870 X2 and Radeon HD 5770 Crossfire both showed impressive gains over their single GPU counterparts, the new Radeon HD 5970 struggled to outpace the Radeon HD 5870.
At 2560x1600 it was just 10% faster, which is a bit worrying considering how the game’s engine has typically worked well with Crossfire technology. Hopefully this won’t become a trend throughout the rest of our tests.









Batman Arkham Asylum is a controversial game to benchmark with, as anti-aliasing in this game strongly favors Nvidia based graphics cards. By removing this visual setting the problem is easily eliminated, though it brings about another small problem: even at 2560x1600 mid-range graphics cards are not exactly put to the test.
The game is also based on the aging Unreal Engine 3, though it is said to use the 3.5 version which features a few upgrades. Still, this shouldn’t provide much trouble for the Radeon HD 5970.
Despite not being a particularly demanding game, Batman Arkham Asylum should demonstrate how various graphics cards scale using this engine -- and the Radeon HD 5970 cleans up. At the maximum tested resolution the Radeon HD 5970 is 27% faster than the GeForce GTX 295 and 58% faster than the Radeon HD 5870. Obviously with an average of 168fps the Radeon HD 5970 has no problems with Batman Arkham Asylum using maximum in-game quality settings with AA/AF disabled.


Benchmarks: Section 8, The Last Remnant









Section 8 is another game based on the original Unreal Engine 3, and again while other Crossfire setups show reasonable performance gains, the Radeon HD 5970 was just 9% faster than the Radeon HD 5870 at 2560x1600. Although this did make the Radeon HD 5970 the fastest graphics card tested, we are hoping to see significantly larger performance gaps between it and its single GPU version.









In The Last Remnant, our last test using the Unreal Engine 3, we see a decent performance margin favoring the Radeon HD 5970 when compared to the Radeon HD 5870. At 2560x1600 the card was 58% faster than the Radeon HD 5870, while it also managed to edge out the GeForce GTX 295 by a 15% margin.
Benchmarks: Wolfenstein, Enemy Territory: Quake Wars









Wolfenstein is one of the newer games in our review and it uses a heavily modified version of the id Tech 4 game engine. At 2560x1600, we were pleased to see that the Radeon HD 5970 was 52% faster than the Radeon HD 5870. This also meant that the Radeon HD 5970 was 43% faster than the GeForce GTX 295 and 52% faster than the Radeon HD 4870 X2. With an average of 93fps at this extreme resolution, the Radeon HD 5970 managed to make the GeForce GTX 295 look slow.









Enemy Territory: Quake Wars employs the original id Tech 4 game engine. Despite it being quite old and testing with maximum in-game quality settings as well as 8xAA/16xAF enabled, the Radeon HD 5970 averaged a staggering 158fps at 2560x1600. This translated to a 49% performance margin over the Radeon HD 5870 and 55% over the Radeon HD 4870 X2.

Power Consumption & Temperatures




In terms of power usage the Radeon HD 5970 is hungry, which was to be expected. With a total system consumption level of 498 watts, the Radeon HD 5970 used slightly less power than the Radeon HD 4870 X2, while consuming 8% more than the GeForce GTX 295.
The Radeon HD 5970 does only use 26% more power than the Radeon HD 5870, which we found startling.



The operating temperature of the Radeon HD 5970 is well within acceptable levels, with an idle temp of 60 degrees. Under load the card heated up to 87 degrees. This stress temperature placed the Radeon HD 5970 alongside the GeForce GTX 275 and the Radeon HD 5870.
The surprising part is that under load the Radeon HD 5970 appeared to generate roughly the same amount of noise as the GeForce GTX 275 and Radeon HD 5870 graphics cards.
Overclocking Performance

Adding value to the Radeon HD 5970 are its stock overclocking abilities that helped us squeeze almost 20% more performance out of it at 2560x1600. The ability to adjust the voltage of any Radeon HD 5970 card should come as a bonus to enthusiast-level consumers and extreme gamers, though we hope AMD is working on providing better software for the consumer.
Although we finished off with a 25% core and memory overclock, it came far from easy using a beta version of the Catalyst drivers. After what seemed like endless stuffing around we achieved a stable overclock with the core running at 900MHz and the memory at 1250MHz.



Overclocking improved the 3Dmark Vantage score at 2560x1600 by 20% as the Radeon HD 5970 was awarded 11099pts. This made the Radeon some 65% faster than the GeForce GTX 295, which was the next fastest graphics card tested.



Company of Heroes Opposing Fronts allowed for a 17% performance increase at 2560x1600 when overclocking the Radeon HD 5970.



The only other game we had time to test after finally achieving a decent overclock was S.T.A.L.K.E.R.: Call of Pripyat where we saw healthy performance gains again. The performance at 2560x1600 was increased by 18% making the Radeon HD 5970 around 78% faster than the Radeon HD 5870.

Final Thoughts

As expected the Radeon HD 5970 is vastly superior to the GeForce GTX 295 in terms of performance beating it in every single test, at all tested resolutions.
On average the Radeon HD 5970 was 53% faster than the GeForce GTX 295 at 2560x1600. Even removing the top three tests where the Radeon led with the biggest margins (BattleForge, Enemy Territory and Street Fighter IV), the HD 5970 still ended up some 34% faster than the GTX 295.
It's easy to conclude from there that the Radeon HD 4870 X2 presented no contention whatsoever, and that ATI's latest dual-GPU Radeon can claim the title of the fastest graphics card currently in the market.
Another interesting statistic is that the Radeon HD 5970 was on average 46% faster than the Radeon HD 5870, while costing 50% more. Assuming that you can increase the core frequency of the Radeon HD 5970 by at least 17% and the memory by 20%, then you can effectively produce a pair of Radeon HD 5870 GPUs in a single board. Once again, for those who can justify the price, we feel that the Radeon HD 5970 provides enthusiast users with a viable alternative towards extreme performance.
It should be noted that under load the Radeon HD 5970 operated at an acceptable volume when running at its default specifications, but this wasn't the case when overclocking. In order to keep the GPUs at safe temperatures, the blower fan was working overtime and in the process created so much noise it was impossible to hear myself think. Those looking into overclocking the already super-fast Radeon HD 5970 will need to delve into alternative cooling methods such as water.
The Radeon HD 5970 is also the largest graphics card we've ever tested with a length of 30cm, it's larger than the 4870 X2 or the GTX 295. This card is not going to be compatible with a wide range of computer cases, so those looking at purchasing it should first make sure their case can accommodate for the EATX (extended ATX) form factor, which measures 30.5cm wide, or roughly the same dimension as the Radeon HD 5970.
Like all multi-GPU graphics cards, the Radeon HD 5970 relies heavily on driver support to perform as intended. Every time a new game is released it is likely that the Radeon HD 5970 will not fully support it (taking advantage of the two GPUs) until AMD updates the Catalyst driver. I'm usually skeptical about multi-GPU technology as the results tend to vary a lot, though admittedly things have improved considerably from where we were a year ago.
Without full Crossfire support the Radeon HD 5970 will perform somewhere in between a single Radeon HD 5870 and 5850 graphics card, which is still pretty decent.
Make it official, the Radeon HD 5970 is the fastest graphics card in the market, outperforming by a long shot previous generation dual-GPU products. We can't decide for you whether it makes sense to spend $600 on this graphics card or not, but at least it's nice having the option.
The next step for AMD/ATI is not to work on their next-generation products, as it is making sure the current Radeons are widely available from retailers. We sure hope the Radeon HD 5970 does not become a soft launch, following the inventory debacle seen with the rest of the series. So, inventory first and working around the drivers' rough edges should make this a great purchase for those who can afford it.
