SilverStone Technology SilverStone 80mm Case Cooling Fan

Comment:
PRO: quiet but effective, CON: RPM speed varies a little unlike the (cheaper) MassCool which is rock steady, RECOMMENDED: yes but you can save a little $ by getting the (slightly louder) MassCool instead

Good value priced quiet case fans. Specs are not correct in description, check manufactors page. Not as quiet as the stealth but at half the price and only a few decibals louder i think its a good trade off.Unless you have money to burn.

This IS a quiet fan and it does have a tach feedback (speed signal) in case you are wondering. I have not run them long, but it seems like a nice fan. I like the 30k MTBF, though I don't know how they achieve it with a slieve bearing. And it does do variable speed based on the input voltage.
