I thought it would be a good idea to replace them with NF-P12 PWM fans since I would like my PC to be as quiet as possible, especially when idle. But... From what I have read in a review, the difference in temperature between using the two fans could be quite large at peak.
Now, I am not actually planning to overclock, so I am fine with a small difference, just not too much. Does anyone have any experience with using NF-P12's on the c14, and is it workable, or is it just a downright bad idea?
I don't have a NF-P12 but the replaced the 140mm fans came with the C14 with 120mm Gentle Typhoons at 1850 RPM. The higher speed GT actually produced better cooling results compared to the original 140mm fans. On the side note, I think you can plug in the 140mm fans into the PWM socket, and your motherboard would still be able to control the fan speed through different voltage. At least, i'm able to control the speed of the 140mm fans of the C14 with my motherboard's auto fan control function. I have a ASRock P67 Extreme 4.
I've also found that it's more efficient to remove the bottom fan on the C14 to provide more clearance for hot air to be removed. But you also need to add two powerful fans on the rear and top of your case as exhaust fans to move the hot air away from the bottom of the C14 heatsink fast enough.Edited by amwayorlando - 7/11/12 at 5:06am
