At 70% fan speed, the SI-100’s included 120x25mm fan outputs around 35dBA noise at distance 50cm. It’s not as objectively quiet as an Noctua’s NF-A12x25 for instance, but still fairly quiet.
We use Cinebench R23 multicore (stability test), for CPU thermal testing. This provides worse case scenario for a given CPU.
Thermalright’s SI-100 is excellent performer, even outpacing the larger, heavier Noctua NH-C14S. It offers reasonable motherboard and RAM compatibility and is aggressively priced relatively to thermal performance.
