Testing the Zalman VF3000N

I first wanted to see how well the coolers could cool the NVIDIA 285 at idle, no load, and the fans speed set to maximum. See can see that at this point the cooler are just about equal, but the more testing we do the more we see a difference. 

FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that’s why FurMark is also a perfect stability and stress test tool (also called GPU burner) for the graphics card.The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection, window size, duration.

By using FurMark we can control how we run our test to ensure that we are creating a larger enough load on the graphic card to see if the cooler is able to handle the heat that is being generated.

This test was a bit hard to make sure that everything was equal since there is no heat sensing Auto Cool for the Zalman VF3000N. So what I did was to set the Zalman all the way down to the lowest fan speed and took the temperature readings.

Again with no real way of knowing what 60% fan speed was on the Zalman I took a guess and turned the dial to about half way around. I actually made sure that it was just under halfway as I wanted to under estimate the speed than to over estimate. For this test I set FurMark to Stability Test, Xtreme Burning Mode, 1280×1024 and the MSAA Samples to 4x. I let the test run for 10 minutes to make sure that the card got stressed and that the highest temperature was reached and stayed there.

Once again for this test I set FurMark to Stability Test, Xtreme Burning Mode, 1280×1024 and the MSAA Samples to 4x. I let the test run for 10 minutes to make sure that the card got stressed and that the highest temperature was reached and stayed there.

I left the settings from the last test the same but this time I applied a 5% overclock to the NVIDIA 285 to give that extra added heat and to see how well the cooler reacted to the pressure.
