Temperatures ran right around 34° C at idle, up to an average of 57° C at full load, and peaking just shy of 60° C. Cranking the fan controller to maximum yields very little apparent visual or audible change, the difference is only 600 rpm, bringing the final fan speed to 1,600 rpm. Let's see if it has any impact on temperature.
As you can see, not much has changed here either. We observe a drop of a single degree at idle, down to 33° C, while loading the processor averages 55° C or a drop of just two degrees. With such a minor difference in performance, and no discernible change in noise, it's hardly worth even having a fan controller at all. Let's see how these numbers stack up against the stock AMD cooler.
The stock AMD cooler for the 965 BE is actually a decent heatsink, similar to the high-end Opteron server coolers. It has a copper bottom base with four individual copper heatpipes leading up into 48 thin soldered fins. Topped off with a quiet 70mm PWM fan, the stock cooler performs decently, yielding a respectable 34° C idle temp and an average load of 61° C, peaking at 63° C. Comparing this to the maximum performance of the SpinQ VT shows a narrow 6° C difference.
