My rig http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03639067-12


Ive swapped in two 3tb toshiba hard drives, a Corsair Coolermaster 600w psu bronze, an asrock h170m pro4 mobo, 16 G Skill 2133 mhz ram, intel i5 6600, and an r9 380x 8gb gpu.


Ok, since I upgraded my mobo, cpu and ram, I have been hearing some sort of coil whine. I had no idea where it was coming from until a couple of days ago. I isolated it with a stethoscope, and it is the PSU. It's a real high pitched noise that my cousin, a pc owner and builder for much longer than I, could not hear. I thought I was going crazy, but upon using the stethoscope, there is an audible whine.


Now, I ordered a new EVGA 650w BQ model as a replacement. After ordering it though, I ran some more ear tests to further isolate the problem, hopefully. Now, I have both of my Toshiba hard drives in the bottom chassis frame that came with the pre build, one, the older 3tb with the os on it, and the other one, with movies, games, etc. In my power options I set the hard disks to shut off after 5 mins when not used, so I could see if turning one of them on would cause the whine to become louder. Sure enough, the 3tb with the OS is always on, and I cant hear the whine much, the 1.5 seagate does not cause an uptick in sound, but when the older 3tb drive turns on, the whine gets louder, at least doubly so.


When I put the stethoscope to my hard drives, there was no whine or anything coming from them, just the normal hdd hum.


So, why would my PSU whine so much louder when the specific 3tb drive is powered up, and is there anything I can do asides from replacing it, and seeing if the new one does it as well? Is there any way to increase or decrease certain voltages in order to ameliorate this problem? It's quite annoying, and I am a complete noob when it comes to terminology, so please, be moron friendly haha.

This could be either just an unfortunate harmonic in the PSU or a sign of a failing one. Given that hard drives only draw about 15W at maximum I suspect that it is a harmonic.


You have a new PSU on order but not yet fitted, if I understand you correctly. Why not wait and see if this problem disappears with the new PSU ?
