  1. Thank you so much for these in-depth reviews! Currently speccing out fans for a water cooled server -extra thick radiators. Truly appreciate your normalized evaluations of CFM, static pressure, and noise at different speeds and sound levels. Your dedication is unmatched. You’ve easily put out the fairest and most comprehensive review of the SilverStone FHS 120X to date. Look forward to more ultra high performance fan writeups! I’m checking the site every day now!
