This part sounded good though. What fans did you go with for replacing with 4 wire. cc- 2 x Cooler Master BladeMaster 80mm PWM High Air Flow Silent Case Fan R4-BM8S-30PK-R0 4 x Cooler Master BladeMaster 92mm PWM High Air Flow Silent Case Fan R4-BM9S-28PK-R0 I also had to replace all the fan cables (in order to keep the hot-plug capability). 6 x Supermicro CBL-0088L Also, since I could no longer use the backplane to power the fans, and the C2SEE only has 5 fan ports, I had to get a PWM Y splitter. Just came across your post and am curious how loud your system is now after the fan upgrades. I am in the process of upgrading my as well with 2 x Cooler Master BladeMaster 80mm PWM High Air Flow Silent Case R4-BM8S-30PK-R0 - 41 CFM, 28dBA - SAME AS YOURS; 4 X Nidec Ultraflo T92E12BMA7-PWM 92mm Case Fan - US $22 each = $88 - http://www.newegg.com/Product/Product.aspx?Item=N82E16835706042 The Nidec fans have a highe CFM then the ones you suggested which is why I have went with them. At full speed they are meant to put out 43dBA which is close to the 53dBA of the standard ones however, these are also PWM so hopefully should running a lot slower then full tilt. Cheers
