Noise

The results of our acoustic measurements performance for Arctic Accelero Xtreme 7970 and MSI Twin Frozr IV coolers are summed up on the following graph:

Arctic cooler once again proved to be exceptionally quiet remaining acoustically comfortable up to 1450 RPM, and practically inaudible up to 100 RPM. It is an absolute leader acoustic performance among all VGA coolers. However, MSI Twin Frozr IV cooler turned out more of a disappointment here: it proved to be even noisier than the reference AMD Radeon HD 7970 cooler, which is also quite noisy. Only due to lower minimal fan speeds Twin Frozr IV cooler outperformed the reference one in maximum noise level test, but it doesn’t save the day against the background of remarkable performance demonstrated by Arctic product. For example, when we tested MSI Twin Frozr IV with the fan rotation speed set manually to 1730 RPM, the noise was around 51 dBA. However, Arctic Accelero Xtreme 7970 generates no more than 45 dBA even with all three of its fans rotating at their maximum speed.

Conclusion

It is time to sum up a few things. Inside a closed system case Arctic Accelero Xtreme 7970 can cool a Radeon HD 7970 3 GB graphics card running at 1140/7128 MHz (1.175 V) with three fans rotating at 880 RPM and maintain its GPU temperature at 69°C, VRM temperature – at 84°C and video memory temperature – at 72°C. And most importantly, you won’t hear this cooler at all. Pretty impressive, isn’t it? This is what real extreme air-cooling for the fastest and most expensive graphics cards should look like! Arctic once again nailed it!

Speaking of the new Arctic Accelero Xtreme 7970, we really can’t come up with any shortcomings. A thick layer of thermal paste can hardly count as one, and the universal compatibility has never been promised anyway. If you are looking for a product that will be indeed universal, Arctic already has new Accelero Xtreme III, which we will review shortly. As for the high price of $98, well, blame the competitors who are still unable to design anything that will beat Accelero Xtreme 7970 in efficiency and noise.

In conclusion we are proud to award Arctic Accelero Xtreme 7970 with our Editor’s Choice title as the best VGA cooler for AMD Radeon HD 79xx products:
