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 ASUS ROG Ryujin 240 in at 59 degrees Celsius. This is a full 4 degrees Celsius warmer than the Corsair H115i Platinum and tied with the SilverStone PF240-RGB. It was also 3 degrees Celsius warmer than the Enermax AQUAFUSION 240. We noted that the max fan speed on the Ryujin 240 was ~2000 RPM while the PF240-ARGB and AQUAFUSION 240 max fan speed was in the 2200-2250 RPM range. 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 while the SilverStone PF240-RGB was the warmest at 62 degrees Celsius. The ASUS ROG Ryujin 240 came in right in the middle of our 240mm coolers with a temperature of 61 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 while the SilverStone PF240-ARGB comes in at 71 degrees Celsius. Splitting these other 240mm coolers is the ASUS ROG Ryujin 240, again, as it comes in at a temperature of 67 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. The 240mm coolers are all at the back of the packs here as you would imagine. However, the ASUS ROG Ryujin does tie the Enermax AQUAFUSION 240 at 82 degrees Celsius and that is better than the SilverStone PF240-RGB which hit 87 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 again bested the Corsair H115i Platinum at 68 degrees Celsius. However, the ASUS ROG Ryujin 240 is not doing as bad as the other 240mm coolers we have seen as it pulls a temperature of 84 degrees Celsius. The Enermax AQUAFUSION 240 and the SilverStone PF240-ARGB, again, we’re in the rear at 87 and 92 degrees Celsius!
