Stock Clock Testing
For our stock clock testing, we have configured our CPU to run at factory settings for speed, and 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 IceSLEET G6 Stealth to 53.25 degrees Celsius while the Cooler Master Hyper 622 Halo Black bested it by a quarter degree at 53 degrees Celsius. It beat out the IceSLEET X7 Dual and the Dark Rock Pro 4 at 55.75 and 57 degrees Celsius respectively.
In this particular lineup, the max fan speed test isn’t the most fair as the IceSLEET G6 Stealth tops out at 1450 RPM. Comparing that to the Hyper 622 Halo Black at 2100RPM, the IceSLEET X7 at 1600RPM, and the Dark Rock Pro at 1500RPM puts the G6 Stealth at a bit of a disadvantage.
1500 RPM Fan
Dropping the fans slightly to 1,500 RPM shook up the playing field a bit as all coolers are now operating at the same speed fans (versus a big variation in the maximum fan testing). The IceSLEET G6 Stealth’s results were unchanged as it was still operating at 1450 RPM.
With everyone running at the same fan speed, the IceSLEET G6 Stealth took the lead at 53.25 degrees Celsius. The Hyper 622 Halo Black slipped into second place at 54.5 degrees Celsius and the IceSLEET X7 Dual and Dark Rock Pro 4 brought up the rear at 56.5 and 57 degrees Celsius respectively.
1000 RPM Fan
Lowering the fan’s RPM further to 1,000 RPM sees the IceSLEET G6 Stealth maintain its lead by 1.25 degrees over the Cooler Master Hyper 622 Halo Black. The Dark Rock Pro 4 and IceSLEET X7 Dual landed at 60 and 60.88 degrees Celsius respectively.
600 RPM Fan
Finally, down at 600 RPM, the IceSLEET G6 Stealth slides into the rear position at 67.25 degrees Celsius, a nearly 10-degree swing from the 1000 RPM level. This differential is one of the highest we’ve seen when dropping the fans. In first and second place are the Dark Rock Pro 4 and IceSLEET X7 Dual turning in temperatures of 65.5 and 66.53 degrees Celsius respectively.
Note that the Hyper 622 Halo Black did not make an appearance on this chart as we were unable to get the fans to operate lower than 900 RPM and that just wouldn’t be fair.
Let’s move on now to look at some overclocking results with our coolers.
