Stock Clock Testing
For our stock clock testing, we have configured our CPU to run at factory settings for speed, voltage. This yields an approximate power at the wall of 185w under load (a 127w differential from idle, which pulls about 58w). This results in the CPU running at 3.7GHz on all cores during the looping rounds of Cinebench R20.
Max Fan
We started our testing today by turning the fans up all the way to 11. This brought the Iceberg Thermal IceSLEET X6 to 56.75 degrees Celsius while the recent IceSLEET X7 Dual came in at 55.75 degrees Celsius. Bracketing these IceSLEET’s is the Cooler Master Hyper 212 EVO which hits 55.5 degrees Celsius and the be quiet! Dark Rock Pro 4 comes in at 57 degrees Celsius. We noted that the max fan speed on the Cooler Master Hyper 212 EVO topped out at 2050 RPM, the Iceberg Thermal IceSLEET X6 topped out at 1900 RPM, the Iceberg Thermal IceSLEET X7 Dual topped out at 1600 RPM, and the be quiet! Dark Rock Pro 4 has the lowest max fan rpm at 1500 RPM.
1500 RPM Fan
Dropping the fans slightly to 1,500 RPM didn’t do much to bring separation between most of our coolers except for the IceSLEET X6. The Cooler Master Hyper 212 EVO came in at 56.88 degrees Celsius while the Iceberg Thermal IceSLEET X7 Dual barely edged it out at 56.5 degrees Celsius. Following this is the be quiet! Dark Rock Pro 4 at 57 degrees Celsius. The Iceberg Thermal IceSLEET X6 brings up the rear at 59.75 degrees Celsius.
1000 RPM Fan
Lowering the fans RPM further to 1,000 RPM sees the IceSLEET X6 catch up to the X7 Dual at 60.88 degrees Celsius. This is interesting as the Cooler Master Hyper 212 EVO hit 60.75 degrees Celsius while the be Quiet! Dark Rock Pro 4 barely edged everyone out at 60 degrees Celsius.
600 RPM Fan
Finally, down at 600 RPM, the Iceberg Thermal IceSLEET X7 Dual and be quiet! Dark Rock Pro 4 are just running away from the pack at 66.63 degrees Celsius and 65.5 degrees Celsius respectively. The Cooler Master Hyper 212 EVO is way behind at 71 degrees Celsius and the Iceberg Thermal IceSLEET X6 is off in another country at 78.5 degrees Celsius.
Let’s move on now to look at some overclocking results with our coolers.
