Recently built a new gaming rig and losing my damn mind trying to figure out why it's so loud.
Current configuration is:
CoolerMaster HAF XB Evo (grill top)
Asus ROG Maximus VIII Hero
i7 6700k default (4.0-4.2GHz)
CoolerMaster MasterLiquid Pro 240 cooler (using a single 120mm fan pulled from CoolerMaster Nepton 240m running at ~670 RPM)
1x80mm Arctic Cooling F8 REV2 (running at ~620 RPM)
Corsair AX750 PSU (original PSU was CoolerMaster V750)
eVGA GeForce GTX 980 SC ACX2.0 (down-clocked to reference)
I've tried eliminating the 80mm fan as it's only to keep air flowing through the hard drive compartment with no change
I replaced the default MasterLiquid fan with 1 from my Nepton cooler as I never heard those fans running but this had no change
For the longest time thought it was the pump but dropping it to ~60% duty cycle had no change.
Replaced the V750 with my old AX750 as the AX750 turns the fan off at low load with no change.
Tried jumping both PSUs outside the case so I could see if there was coil-whine in certain positions but they were nearly inaudible outside the case.
Sound is present when the fans on 980 are not running
I do have 3x4TB WD Blacks running in it but system was loud before I installed these (only qualm is 1 drive has weird seek pattern every so often)
At this point, willing to try eliminating the radiator fan as it may just be airflow noise pulling through front grill AND pushing through the radiator. Will try this tonight by plugging the pump into CPU_FAN header.
Beyond this out of ideas. Anything anyone else can think of? I have the original Nepton cooler with the other Nepton fan installed on an i7 3770 I've rebuilt for a game server but with CPU at max load I still can barely hear this system. My new rig at idle is a leaf-blower compared to the server at load.
Did notice during a failed overclocking attempt that a shutdown didn't properly kill power once Windows had fully closed out and the noise vanished completely while pump and 80mm fan were still running. Was not able to confirm if the 120mm radiator fan was still running or not.
