For our OC testing, we have configured our CPU to run 4100MHz on all cores and set the voltage to 1.3875V. This yields an approximate power at the wall of 255w under load (a 197w differential from idle, which pulls about 58w). This results in the CPU running at 4.1GHz on all cores during the looping rounds of Cinebench R20.
Running our HSFs at full tilt lead to the Iceberg Thermal IceSLEET X7 Dual posting a temperature of 79 degrees Celsius. It trailed the Cooler Master Hyper 212 EVO (77.38 degrees Celsius) and be quiet! Dark Pro 4 (78 degrees Celsius). The max fan speed on the Cooler Master Hyper 212 EVO was 2050 RPM and 1600 RPM on the Iceberg Thermal IceSLEET X7 Dual. The be quiet! Dark Pro 4 was even lower at 1500 RPM.
1500 RPM Fans
At the 1500 RPM fan speed, the Cooler Master Hyper 212 EVO posted a value of 79.75 degrees Celsius while the Iceberg Thermal IceSLEET X7 Dual was right on its heels at 79.88 degrees Celsius. When we dropped down to the 1000 RPM fan speed, we were greeted with system crashes, so we put a halt to the testing at that time.
Now that we have seen how all of our units cool, lets see if we can still hear!
