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 which brought the Corsair iCUE H100i Elite Capellix to turn in a score of 58 degrees. Compared to the other 240mm coolers in the lineup, it stepped ahead of the SilverStone PF240-RGB and ASUS Ryujin 240 by a degree but the Enermax AQUAFUSION 240 maintained its lead.
We noted that the max fan speed on the ASUS Ryujin 240 was 2,000 RPM. The PF240-ARGB and AQUAFUSION 240 were in the 2,200-2,250 RPM range while the Corsair H115i Platinum topped out at 1,800 RPM. The CORSAIR iCUE H100i ELITE CAPELLIX was in a different league with max fan speeds of 2,400 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. Among 240mm coolers, the Enermax AQUAFUSION 240 did the best at 60 degrees Celsius and then the SilverStone PF240-ARGB at 62 degrees Celsius. In the rear was the CORSAIR iCUE H100i ELITE CAPELLIX at 63 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 a temperature of 66 degrees Celsius. This is followed by ASUS Ryujin 240 at 67 degrees Celsius and then the SilverStone PF240-ARGB comes in at 71 degrees Celsius. The CORSAIR iCUE H100i ELITE CAPELLIX continues to trail all of the 240mm coolers at 73 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/ASUS Ryujin 240 and SilverStone PF240-ARGB are suffering at 82 and 87 degrees Celsius respectively. The Corsair iCUE H100i Elite Capellix, however, suffering worse at 93 degrees Celsius. Of note, the AIO coolant temperature in the Corsair iCUE H100i Elite Capellix reached critical and that ended its testing for our stock clocks.
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. The Enermax AQUAFUSION 240 and the SilverStone PF240-ARGB were in the rear at 87 and 92 degrees Celsius for those units that could complete the test. The CORSAIR iCUE H100i ELITE CAPELLIX, however, could not be tested because of the critical coolant temperature issue from the previous test.
Let’s move on now to look at some Mild Overclocking results with our coolers.
