out of curiosity, know the performance #'s (CFM/watts/etc) on the stock fan you replaced?
Didn't replace a stock fan. The three SP120's were going into a 360 xspc radiator, which i was going to use to watercool my bitburner boards. That did not pan out as i thought, so i just took them out and used them for less than 2 hours and pointed them at my BFL products..
But the specs of these fans can be found online. I am replacing them with Noctua NF-F12's which are only a tad quieter, and less performance..
