Cooling Efficiency Tests
AT first let’s see how Deepcool V6000 and its competitor cope with overclocked GeForce GTX 560:
Although EVGA GeForce GTX 560 Superclocked, which we are going to review in one of our next articles, has a pretty efficient proprietary cooler, Deepcool V6000 easily outperformed it. At maximum rotation speed of its two fans, V6000 delivered 4 degrees better GPU temperature in games and 3 degrees better temperature in FurMark test, even though the fan of the default cooler worked at its maximum speed of 4140 RPM, which is undoubtedly way louder than two Deepcool UF92 fans at 1800 RPM. V6000 is also the winner in the quiet mode being 9°C better than the EVGA cooler in games and 2°C better under FurMark load. At the same time, I have to draw your attention to the fact that GeForce GTX 560 fan sped up to 3180 RPM, while UF92 worked at only 1050 RPM.
The next test is a little more serious: Deepcool V6000 has to cope with a Radeon HD 6970, which is one of the hottest graphics cards available today. Besides, there are more competitors in this segment anyway. Let’s take a look:
And again the new Deepcool product did very well, even though it failed to ultimately win. Triple-fan Arctic Cooling XTREME remains undefeated. V6000 did yield to the leader substantially: 7°C at maximum speed and 9°C in very quiet mode in the gaming tests, and 9°C and 13°C respectively in FurMark. I have to say that V6000 looks very appealing against the competition represented by the original VTX3D Radeon HD 6970 cooler and especially the reference AMD Radeon HD 6970 cooler. And all that doesn’t yet take acoustics into account, which is exactly what we are going to talk about now.
The results of our acoustic tests of Deepcool V6000 in comparison against Arctic Cooling Accelero XTREME 5870, default EVGA GeForce GTX 560 Superclocked and VTX3D Radeon HD 6970 coolers and the reference cooler of the AMD Radeon HD 6970 are given in the table and on the diagram below:
The results speak for themselves: Deepcool V6000 is one of the quietest VGA coolers available today. Its high-quality fans with anti-vibration coating make the cooler exceptionally quiet at up to 1100 RPM and acoustically comfortable at up to 1300-1350 RPM. Therefore, in this aspect the new Deepcool V6000 becomes superior to the former leader Arctic Cooling Accelero XTTEME 5870. And even beyond 1350 RPM and the subjective level of acoustic comfort, which we set at 36 dBA, V600 is not offensive at all, unlike reference coolers of AMD Radeon HD 6970 or Nvidia GeForce GTX 560. Therefore, Deepcool V600 will be a perfect choice for the owners of quiet systems, although it is important to remember that the rotation speed has to be lowered manually below the nominal setting, because, unfortunately, the manufacturer didn’t implement this option.
Summing up everything we discussed today we can conclude that the new Deepcool cooler really turned out great. V6000 offers pretty high cooling efficiency, comes with high-quality quiet fans, is truly universal, simple to install and looks great on a graphics card. At the same time, unlike the V4000 model, which we practically titled the ideal cooler for entry-level graphics cards, the flagship V6000 solution has a few drawbacks, which you should keep in mind when shopping for a VGA cooler. First, remember that this cooler will take away three PCI slots next to the graphics card and will work better if the fourth slot is also empty, to ensure that there is proper airflow coming towards the cooling fans. Also note that the fans do not support PWM control and come without a variator, which could help make the graphics card practically noiseless when it works in 2D mode. By the way, it could also be interesting to equip V6000 with UF92 PWM fans working at up to 2500 RPM speeds, for instance. It could also be interesting to see how the copper V6000 compares against the aluminum. As you can see, we have a ton of ideas, but as usual, the choice is yours after all :)
