The Delta 120 x 38mm Super Extreme High-Speed Fan is an outrageously high performance fan that moves over 240 cubic feet of air every minute. It also has an amazing near 4:1 airflow to noise ratio. This fan is a great choice for cooling components that heat up to temperatures similar to that of the sun's core.
Note: Sleeving and power connectors are optional extras.

if 60 dB doesn''t bother you, this is the fan of fans.

few fans over 200CFM this "quiet"-it''s loud to be sure, but there''s no high pitched whine due to lack of directional fins. i have a pile of these and ALL start up and spin at 5V. with a fan controller that can take the power of these you have quite a range to work with.
W/ a dense rad (and by that i mean black ice GTX or on a phase change unit) these are unreal.
