Arctic Cooling Accelero Twin Turbo VGA Cooler Review

Conclusions

In our tests with a Radeon HD 4870 Accelero Twin Turbo achieved a performance worst than ATI’s stock cooler when we connected the reviewed cooler to the standard fan connector available on the video card (the temperature of the air being thrown out of the system dropped dramatically, however, from 63° C to 51° C). So we recommend you to connect the reviewed cooler directly to the system power supply.

You have two options when connecting Accelero Twin Turbo to the power supply: +7 V (lower fan speed and thus lower noise level) or +12 V (higher fan speed and thus higher noise level). At +7 V Accelero Twin Turbo was a little bit better than ATI’s stock cooler, but if you are really worried about temperature you should run this product at +12 V, where it lower the GPU temperature by 15° C, memory temperature by 12° C and the hot air being thrown out of the system by amazing 26° C. The heatsink was running 11° C cooler than the heatsink from the stock cooler, which is nice.

It is always important to remember that these results were achieved with a Radeon HD 4870, a GPU that is famous to heat a lot. You may get better results with different video cards.

The only thing we really didn’t like about this product is that after installing it our video card was now taking three slots from the motherboard and case, covering the second PCI Express x16 slot from our motherboard. This was a real bummer, since we originally had two video cards installed.

So if you have an SLI or a CrossFire system forget about this cooler. It will prevent you from installing your second video card. If you are running a single-VGA system, however, Accelero Twin Turbo may be a good option.
