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 X7 Dual to 55.75 degrees Celsius. This is almost identical to the Cooler Master Hyper 212 EVO which hits 55.5 degrees Celsius. We noted that the max fan speed on the Cooler Master Hyper 212 EVO topped out at 2050 RPM and the Iceberg Thermal IceSLEET X7 Dual topped out at 1600 RPM. The be quiet! Dark Rock Pro 4 has lowest max fan rpm at 1500 RPM.

Dropping the fans slightly to 1,500 RPM didn’t do much to bring separation between our coolers. The Cooler Master Hyper 212 EVO came in at 56.88 degrees Celsius while the real kicker was the Iceberg Thermal IceSLEET X7 Dual barely edged it out at 56.5 degrees Celsius. Unsurprisingly, given its max fan RPM, the be quiet! Dark Rock Pro 4 does not see a change relative to the Max Fan RPM test.

Lowering the fans RPM further to 1,000 RPM sees the IceSLEET X7 Dual stay very close to the Cooler Master Hyper 212 EVO (60.88 degrees Celsius versus 60.75 degrees Celsius). The be Quiet! Dark Rock Pro 4, however, barely edged everyone out at 60 degrees Celsius.

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 respectively. The Cooler Master Hyper 212 EVO is way behind at 71 degrees Celsius.

Let’s move on now to look at some overclocking results with our coolers.
