Arctic Cooling Accelero XTREME 4870X2

TESTING METHODOLOGY

To thoroughly test the Artic Cooling Accelero XTREME 4870X2 GPU cooler load temperature, I ran several hours of Hawx. For idle temperatures I allowed the video card to idle for roughly 30 minutes. The hottest temperature the GPU reached was the temperature I recorded. My roommate does not like his video cards overclocked, so I was unable to get any overclocked temperatures. I did not allow the video card BIOS to control the fan on the HD4870X2, the reason for this was because anything less then a 50% on the fan this video card would reach above the 70°C temperature mark. This is my personal temperature limit I set, and try and keep my video cards below this point. The fans on the Accelero XTREME 4870X2 were also set to a 75% for a better comparison.

RESULTS

Idle

Looking at the idle temperatures of the 4870X2 video card, the stock cooler is more then capable of handling the heat output of this video card. Keep in mind the fan on the 4870X2 stock cooler is set at 75%, and it sounds like a jet engine. The Accelero XTREME 4870X2 GPU cooler was able to better the original cooler by 7°C. Even at a 75% spin rate on three fans, this cooler was barely audible. Lets see how things look once we start working the 4870X2 video card on full load.

Full Load

If this was my 4870X2 video card I would have already freaked out once my temperatures reached 70°C. Since my roommate is not as anal as I am when it comes to temperatures it was ok to him, but having this temperature was at a cost of noise and lots of noise. The Accelero XTREME 4870X2 GPU cooler not only quietened down a loud computer component, it was able to keep the 4870X2 below 55°C on a full load. I don't know about you, but I call this exceptional.
