Cooler Master Hyper N520 Heatsink

CPU Tests
 
The CPU tests were conducted at both stock and overclocked stated. The overclock used was 3.6Ghz using 1.45v.
 
CPU temps
 
As you can see the N520 held the little E7200 to perfectly acceptable temperatures in both stock and overclocked states. Even with what some would dub as excessive Vcore for a 45nm chip being pushed through it. Idle temperatures were too close to call, suggesting that the idle heat load was handled with ease.
 
 
Simulated Load Tests
 
STL_Graph
 
The results from the simulated load testing make some interesting reading. The Intel stock cooler pretty much fell flat on its face at the 150w mark, exceeding the 80°C. Where as the race between the OCZ Vendetta II and the N520 was much, much closer. Both held at more than acceptable temperatures all the way up to the 200w mark, where by they still didn’t allow the reading to slip over 60°C. The OCZ Vendetta managed to edge out the N520 by the smallest of margins in this test. But it shows that the N520 is certainly not a sloppy product.
 
 
Noise
 
The noise each cooler made during the testing process was a bit subjective to which test was being performed at the time. On the simulator, each coolers fan was run at its maximum 12v to make sure that there was no throttling involved and thus keeping it fair. Out of the three coolers tested here, the N520 was actually the quietest in this state. It wasn’t silent, but if you have a pair of medium flow 80mm fans in a case with it they would drown out the noise emitted by the dual 90mm fans with relative ease.
 
Testing on a real motherboard however, the N520 suffered a little for not having a PWM controlled fan, and thus when throttling did occur while the CPU was idle or under little load, the Vendetta II managed to be a whisper quieter than the N520.Â
