To test all heatsinks/fans in this comparison, Hi Tech Legion will maintain an ambient room temperature of 23C. Temperatures will be climate controlled in all instances, so there will be no variance in benchmarks. Noctua NT-H1 Thermal Compound will be used for all comparison units. All heatsinks/fans will be benchmarked in the exact case as its comparisons, unless otherwise specified. HTL does not benchmark heatsinks/fans on a work bench - this is an attempt to show real world statistics. Temperatures will be calculated using AIDA64 and will all be measured in Celsius. All load temperatures will be at 100%, achieved by using OCCT, which will be run for 30 minutes before temperatures are measured.

In this review, the $119.99 MSRP Corsair H100i CPU Cooler will be tested against the following comparison units. The units were tested in succession in the same build, and only results from these tests were used.

Corsair H100i Benchmarks stock

 Corsair H100i Benchmarks Overclocked

All power saving features were disabled in the BIOS and on Windows on both Stock and Overclocked, with the Windows Power Saving feature set to "High Performance". The top 140mm exhaust fan on the Switch 810 was removed and all fans were attached directly to the power supply via molex to 4-pin/3-pin adapters to ensure full RPM. The H100 and H100i fans were attached through the pump unit and the H100i settings were adjusted via Corsair Link software.
