But if you can live with 21dBA get the thermaltake thunderblades for $5 at Xoxide, 78cfm 21dBA
Im using a TT 120mm on my heatsink. Doesn't sound anything like a hair dryer though. You can hear the air moving but nothing drastic. Meh for $5, it works for me. There are fans out there more silent but cost more than what I want to spend. I ordered 6 more TT 120's and 1 TT 80mm for my case, I'll be installing them tonight after work. If the baby wakes up screaming wtf after I power it up then I'll just keep the stock fans in and post here :lol:
