Thermal and Audio Results

EK Water Blocks EK-FC7950[EN] Full Cover GPU Water Block Review 97 | TweakTown.com

I would first like to thank HIS and GIGABYTE for supplying products for me to test with.

To obtain the results you are about to see in the charts I used a combination of Unigine Heaven Bench 3.0, GPU-Z and the HIS iTurbo software to overclock, measure temperatures and provide the stress load to heat up the components of the Radeon HD 7950 IceQ Turbo used in these tests. Keeping an ambient temperature of between 24.5° C and 25.5°C the HD 7950 was booted an allowed to sit idle for 10 minutes before I opened GPU-Z to read the measurements, even there I allowed the graphs to fill up completely before I used those temperatures for idle results. For the loaded testing, stock and overclocked, I used Heaven Bench with the setting in the image below and ran the program for roughly 30 minutes to get to the maximum temperature that the video card would produce.

To give the card the most abuse I could derive from this test, I was sure to maximize the tessellation and the AA and AF settings to make the video card produce the best quality image and maximize the power. Resolution makes little difference in the maximum temperatures, so I ran in windowed mode to get screen captures with GPU-Z to back up my work.

Getting right down to it, we can see that there is little difference in the idle temperatures, but there was a little bit of heat dump coming from the CPU in the loop as well. With just the video card alone in a loop, I think I could have seen 27°C at idle, but 29°C is fine with me at this point.

When we added the stress to the GPU with the EK-FC7950[EN] in place we see a huge difference in results. With the stock fan profile controlling the fans slope, at stock I got to 63° and when overclocked I hit 70° with the IceQ Turbo fan. On water with this EK product we got a 26° drop at stock and a 29° drop when overclocked.

As for the audio results, these are very subjective. For my results I was idling at 25 dB and with 12V to the fans I had 45 dB from the Noctua NF-F12PWM fans I use. Most users will go for higher RPM fans with good static pressure, but very few can deliver the performance and stupidly low audio results that these fans deliver from Noctua.
