Xigmatek Aegir SD128264 CPU Cooler Review
Luke Hill / 13 years ago
Measuring temperatures is all about being consistent; therefore we make sure that the test is kept completely fair so that none of the coolers are at a disadvantage. We measure the CPU temperature using HWMonitor after a 15 minute idle period. We then measure the CPU temperature using HWMonitor after a 15 minute load period using Prime95 with the small FFTs setting.
The chart shows the delta CPU temperature (difference between ambient temperature and recorded CPU temperature). This way we can fairly compare each cooler without presenting any inaccuracies due to slight fluctuations in the ambient temperature or unfair results.
Here is an example of how to understand delta temperatures. “If the ambient (room) temperature is 25C and the recorded CPU temperature is 65C, the delta temperature is the CPU’s temperature rise above ambient temperature, therefore the delta temperature in this case would be 40C. If the ambient temperature is 23C and the recorded CPU Temperature is 80C, the delta temperature in this case would be 57C. Delta temperature = Recorded CPU temperature – Ambient temperature”
We can see from the start that Xigmatek’s Aegir is going to have a tough time against the very competitive Cooler Master V6GT which can be had for as little as £30/$49 on the correct day. The difference in load temperatures between the V6GT, Hyper 212 Plus and Aegir are small enough to call this test a draw. Phanteks’ air cooling king, the PH-TC14PE shows that it will be retaining its crown by offering around a 9% load performance benefit over the SD128264, albeit with a 100% price increase.
