Expreview has tested Inno3D‘s GTX 470 iChill cooled by an Arctic Cooling VGA cooler. According to Inno3D, the GPU temperature in full stress mode is 20°C below the reference GTX 470 card. To verify this statement, FurMark has been used to fully load the GPU.
Here are the clocks of this GTX 470:
– GPU: 630MHz (ref=607MHz)
– Shader: 1260MHz (ref=1215MHz)
– Memory speed: 850MHz real speed or 1700 DDR speed. Ref=837MHz real speed.
As you can see, this GTX 470 is pre-overclocked.
Inno3D GTX 470 iChill Arctic Cooling – Default clocks (GPU=630MHz, mem=850MHz) – Stressed by FurMark – GPU Temp: 66°C
Inno3D GTX 470 iChill Arctic Cooling – Overclocked (GPU=750MHz, mem=900MHz) – Stressed by FurMark – GPU Temp: 69°C
GTX 470 with reference VGA cooler – Same clocks than Inno3D’s GTX 470 – Stressed by FurMark – GPU Temp: 92°C
With default clocks (pre-overclocked) the GPU temp does not excedd 66°C. And with overclocked settings (GPU=750MHz, mem=900MHz), the GPU reaches 69°C. These temperature are really nice! So even with overclocked settings, the GPU temperature is more than 20° below the ref GTX 470.
