OC Testing
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.
Max Fans
Running our HSFs at full tilt leads to the Cooler Master MASTERAIR MA824 STEALTH posting a temperature of 67 degrees Celsius whoops the competition with the MASTERAIR MA624 up at 75.5 degrees Celsius and the be quiet! Dark Rock Pro 4 at 78 degrees Celsius. The X7 Dual brought up the rear at a temperature of 79 degrees Celsius.
Keep in mind that maximum fan speed varies between the units in this test – the Cooler Master MASTERAIR MA824 STEALTH topped out at 1900 and 1550 RPM, the Iceberg Thermal IceSLEET X7 Dual topped out at 1600 RPM, the be quiet! Dark Rock Pro 4 has the lowest max fan rpm at 1500 RPM and the Cooler Master MASTERAIR MA624 STEALTH tipped in just under 1500 RPM.
1500 RPM Fans
At the 1500 RPM fan speed, the Cooler Master MASTERAIR MA824 STEALTH leads the charge at 67.75 degrees Celsius with the MASTERAIR MA624 Stealth trailing behind at 75.5 degrees Celsius. The be quiet! Dark Rock Pro 4 landed at 78 degrees Celsius while the Iceberg Thermal IceSLEET X7 Dual was right on its heels at 79.88 degrees Celsius.
1000 RPM Fans
At the 1000 RPM fan speed, the Cooler Master MASTERAIR MA824 STEALTH posted a temperature of 72.75 degrees Celsius with the MASTERAIR MA624 STEALTH about 6 degrees behind at 78.5 degrees Celsius. The be quiet! Dark Rock Pro 4 posted a value of 82.5 degrees Celsius. Iceberg Thermal IceSLEET X7 Dual failed to keep the temperature in check here and our system crashed.
Now that we have seen how all of our units cool, let’s see if we can still hear!
