I will be testing the NorthQ Siberian Tiger on my AMD 6400+ X2 BE processor which runs at 3.2Ghz with 1.4 volts by default. Two overclocked settings were used, the first at 3.3Ghz with stock voltage, the second at 3.4Ghz with 1.5 volts. I used the latest Core Temp 0.99 software to log temperature readings over ten to fifteen minute intervals, then averaged the temps together for a final result. Idle temps were taken after booting to Windows and all processes completed. Load temps were generated by running the F@H SMP Client to bring both cores to 100% utilization.
The NorthQ cooler performed very well, showing only a three degree increase under load when overvolting by a tenth. Although the temps registered were not quite as good as my usual liquid cooling setup, the Siberian Tiger's footprint is much smaller. And even the best air coolers would be hard pressed to keep load temps under 50° C with this CPU, in fact many have failed to keep the system stable at all!
Let's wrap things up with a conclusion.
