i am quite new to this so the first thing i did when i finished building my pc and noticing that it was quite loud was to google rear fan issues with the fractal design r3 case… and was somewhat relieved to find out i was not the only one…

however (and perhaps you’re better at this than i am and this won’t help) after re-reading carefully all the data reported by the sensors and my mother board documentation (it’s an asus p8z68), i noticed that my fan didn’t come up as “chassis fan 1” in the sensor data as it should: i had connected the 3 pin connector of my rear fan to the wrong place on the motherboard (“pwr” rather than “cha”)! turns out it has to go in what looks like it was designed for a 4 pin connector, but only uses 3 of them. now the pc is a lot quieter. my guess is that the speed was not controlled properly.

if i’m wrong do let me know… but if you have noise level issues with your rear fan on this case, do double check that you’ve got it plugged into the right place on the motherboard…

cheers
