FANS

The SI-100's included 120x25mm fan is not as subjectively quiet or in same class as the NF-A12x25 for instance, but still decent performer for the price of the cooler.

TEST SYSTEM

Testing is carried out on the BC1 Mini (open testbench) in 20°C ambient room temperature.

FINAL THOUGHTS

Thermalright’s SI-100 is excellent cooler outpacing the larger, heavier Noctua NH-C14S in our testing. It offers solid motherboard and RAM compatibility and is aggressively priced relative to its thermal performance. There also aren't many competing CPU coolers in this height class.
