i have 2 very giant very quiet fans on the side of my case (adjustable speed, but i leave them all the way up since they are silent), a crap fan in the back, and 2 adjustable 80mm fans on top. the top 80mm fans get CRAZY loud when i turn them up. idr the RPMs but i know it was quite high. the big ones on the side only get to like 5000 or so
Not sure what classifies as a server fan. Ball Bearing 5500 RPM 120mm 252.85 CFM 66.5 dBA 12V Operating Voltage Range : 8 ~ 13.2V Rated Current: 4.80 amp Rated Input Power: 48W Air Pressure: 35.877 mm H²O
Is a beast of a fan, definitely not meant for the average desktop.
