Temperature Testing

Software and driver installation of the Kuhler 920 cooler came next, and on boot up it was immediately recognized in Windows. The software gives you three options to choose from for operating speed (specifically, fan RPMs): Silent, Extreme, and Custom. Silent is obviously geared to low noise setup that will cause the temperatures to run warmer as a result, with the fan fan speeds about 600-650 RPM. The Extreme preset is maximum power and cooling effectiveness, with the fans pushing 110CFM and but runs very loud, almost like a hair dryer actually. And finally, Custom lets you manually set the speed in order to find perhaps a good balance between noise and thermal performance.

The software interface allows two color choices of the skin display, black or blue. What you’re seeing starting on the top left is the water temps, fan speed, sound levels, and pump RPM. The fan speed in the Silent mode are very low and barely audible.

Below, we have stock settings with no load, ambient of 20°C, and the Silent preset, resulting in idle temperatures of 22°C.

Now, with our Phenom II X6 1100 overclocked to 3.8GHz, at idle, the temperatures sat at only 26°C to 27°C.

However, CPU load temperatures are where products are made or broken. Running in Silent mode at stock settings, running LinX for 5 passes at 100% load and letting the software take over, we have a high of 42°C. This is a good result.

Now we get into real world for the gamers and enthusiasts by pushing the envelope with an overclock of 4.0GHz and twenty runs in LinX at 100% load. I went with Custom settings and bumped up the fan speed quite a bit.

Temperatures crested at a high of 49°C, coolant temps at 40°C, fan speeds average of 1600 RPM, and pump speeds averaged out at 2942 RPM. This is, I believe, an excellent balance between acceptable noise levels and performance, particularly in an overclocked situation.

Let’s wrap things up next.
