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.
Max Fans – 100% Pump Speed
We started by turning the fans up all the way which brought the Enermax LIQTECH II 360 to 56 degrees Celsius where it was barely edged out by the Corsair H115i Platinum at 55 degrees Celsius. We noted that the max fan speed on the LIQTECH was 2250 RPM and the H115i was 1800 RPM.
1500 RPM Fans – 100% Pump Speed
Dropping the fans slightly to 1,500 RPM brought the units added a little more distance with the Enermax LIQTECH II 360 at 59 degrees Celsius compared to the slightly cooler Corsair H115i Plaintum at 57 degrees Celsius.
1000 RPM Fans – 100% Pump Speed
Lower the fans further to 1,000 RPM continued the trend with the Enermax LIQTECH II 360 checking in at 65 degrees Celsius and the Corsair H115i Platinum 8.3% cooler at 60 degrees Celsius.
600 RPM Fans – 100% Pump Speed
Finally, down at 600 RPM with the pump still at 100% provided an audible whir in the room. The Enermax LIQTECH II 360 took the lead at 68 degrees Celsius. The Corsair H115i Platinum arrived at 71 degrees Celsius.
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 checked in at 68 degrees Celsius. This is 7.3% cooler than the Corsair H115i Platinum which landed at 73 degrees Celsius.
