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 Cooler Master Hyper 622 Halo Black to 53 degrees Celsius which lead the IceSLEET X7 Dual at 55.75 degrees Celsius. Just behind the IceSLEET, we found the Cooler Master MasterAir MA6241 Stealth at 56 degrees and the be quiet! Dark Rock Pro 4 at 57 degrees.
We noted that the max fan speed on the Cooler Master Hyper 622 Black topped out at 2100 RPM, the Iceberg Thermal IceSLEET X7 Dual topped out at 1600 RPM, the be quiet! Dark Rock Pro 4 topped out at 1500 RPM and the MasterAir MA 624 Stealth has the lowest max fan rpm at 1400 RPM. This variation of maximum fan speed certainly makes a big difference in top performance.
1500 RPM Fan
Dropping the fans slightly to 1,500 RPM (or, still maxed out at 1400 RPM for the MasterAir MA624) shook up the playing field a bit. The Cooler Master Hyper 622 Halo Black came in at 54.5 degrees Celsius. The MasterAir MA624 Stealth moved up a position with 56 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.
1000 RPM Fan
Lowering the fans RPM further to 1,000 RPM sees the Cooler Mater Hyper 622 Halo Black maintain its lead with a temperature of 58.75 degrees Celsius. The be Quiet! Dark Rock Pro 4 and MasterAir MA624 Stealth tied for second at 60 degrees Celsius. Bringing up the rear, the IceSLEET X7 Dual delivered 60.88 degrees Celsius as its result.
600 RPM Fan
While we typically will test fans at the 600 RPM mark, we were not able to get the Cooler Master Hyper 622 Halo Black fans to crank themselves down below about 900 RPM, thus, we are excluding the 600 RPM fan testing from our evaluation.
Let’s move on now to look at some overclocking results with our coolers.
