Stock Clock Testing
For our stock clock testing, we have configured our CPU to run at factory settings for speed, voltage, and configured memory to XMP mode. This yields an approximate power at the wall of 300w under load (a 200w differential from idle, which pulls about 100w). This results in the CPU running at 3.8GHz on all cores during the looping rounds of Cinebench R20. You can read more about this in our introduction article here.
Max Fans – 100% Pump Speed
We started our testing by turning the fans up all the way to 11. This brought the Corsair H115i Platinum to 55 degrees Celsius. This is a full 4 degrees Celsius cooler than the SilverStone PF240-RGB and 1 degree Celsius cooler than the Enermax AQUAFUSION 240 (or most closely sized competitors). We noted that the max fan speed on the PF240-ARGB and AQUAFUSION 240 was 2200-2250 RPM range while the Corsair H115i Platinum topped out at 1800 RPM.
1500 RPM Fans – 100% Pump Speed
Dropping the fans slightly to 1,500 RPM brought the units a little more separation. The Corsair H115i Platinum was the coolest at 57 degrees Celsius followed by the Enermax AQUAFUSION 240 at 60 degrees Celsius and then the SilverStone PF240-ARGB at 62 degrees Celsius.
1000 RPM Fans – 100% Pump Speed
Lowering the fans RPM further to 1,000 RPM sees the Corsair H115i Platinum cooler come in the coolest at 60 degrees Celsius. The Enermax AQUAFUSION 240 sees temperature of 66 degrees Celsius while the SilverStone PF240-ARGB comes in at 71 degrees Celsius.
600 RPM Fans – 100% Pump Speed
Finally, down at 600 RPM, with the pump still at 100%, the Enermax LIQTECH II 360 takes the lead at 68 degrees Celsius. However, it is followed by the Corsair H115i Platinum at 71 degrees Celsius. The Enermax AQUAFUSION 240 and SilverStone PF240-ARGB are suffering in the rear of the pack at 82 and 87 degrees Celsius respectively.
600 RPM Fans – 50% Pump Speed
To silence the pump, we dropped its speed to 50% giving us our quietest configuration to test. The Enermax LIQTECH II 360 again bested the Corsair H115i Platinum at 68 degrees Celsius. However, Corsair H115i Platinum did post a respectable 73 degrees Celsius result. The Enermax AQUAFUSION 240 and the SilverStone PF240-ARGB, again, were in the rear at 87 and 92 degrees Celsius!
Let’s move on now to look at some Mild Overclocking results with our coolers.
