Putting the CPU under a significant overclock reveals H100i’s true strength; again the record has been broken by over 5C, furthermore, in Quiet Mode the H100i beats the H100 in High Mode, establishing itself as the best CPU cooler we have tested. The new pump, tubing and cooling fans have obviously helped enormously with the heat dissipation. A new standard is set. It's important to note that the H100 has the following fan speed settings as previously tested: 1300 RPM (Low)2000RPM (Mid) 2500RPM (High) - by knowing these values we can see H100's fans are operating at the same speeds as H100i and results are comparable.

Quiet Mode: 1100RPM – Low noise and relatively unnoticeable.
Maximum Mode: 2500RPM – Much more noticeable compared to quiet mode but not as disruptive as other 2500RPM fans.
