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 CORSAIR A115 to 49.5 degrees Celsius which outpaced the MasterAir MA824’s 52 degrees, the IceSLEET G6 Stealth’s 53.25 degrees and the Dark Rock Pro 4’s 57 degrees Celsius.
We noted that the max fan speed on the CORSAIR A115 topped out at 1600 RPM, the MasterAir 824 topped out at 1900/1550 RPM, the IceSLEET G6 Stealth topped out at 1450 RPM and the Dark Rock Pro 4 at 1300/1500 RPM.
1500 RPM Fan
Dropping the fans slightly to 1,500 RPM didn’t do much to bring separation between most of our coolers as quite frankly, the 1500 RPM level is about where their maximum operating speed hangs out. The CORSAIR A115 maintained its lead at 49.75 degrees Celsius, significantly ahead of the rest of the field.
1000 RPM Fan
Lowering the fans RPM further to 1,000 RPM sees the CORSAIR A115 at 52.25 degrees, leading the MasterAir 824 by three degrees Celsius. In turn the IceSLEET G6 Stealth is 2.25 degrees warmer and another 2.5 degrees warmer is the Dark Rock Pro 4.
600 RPM Fan
Finally, down at 600 RPM, the CORSAIR A115 maintains its lead at 57.5 degrees Celsius. The MasterAir 824 and Dark Rock Pro 4 land 4 and 9 degrees warmer, respectively. The IceSLEET G6 Stealth fell into last place at 67.25 degrees which was expected given that it is the only single fan design in the line up.
Let’s move on now to look at some overclocking results with our coolers.
