I just built a gaming system, and as of day 3 of using it (days 1-2 there were no issues while using) there is a low-pitch, intermittent humming/buzzing sound coming from the area of the heatsink/cpu. I can't localize it any further. It is on and off, maybe about 3-4 seconds on, then off, and so on. It starts up usually about 30-45 seconds after booting up (although sometimes I do notice a faint quick buzz right at start up, maybe a change in tone - this leads me to believe there is something interfering with the fan?). I am running open case at the moment.
Here are my specs:
Mobo: ASUS Z87-Deluxe
CPU: i5-4670k Haswell
Cooler: Phanteks PH-TC14PE
Video Card: GeForce GTX 780
HDD: Samsung 840 Series 500 GB SSD
RAM: Corsair Vengeance LP 16 GB (2x 8 GB)
Power Supply: Seasonic SS-1250XM (1250w)
Case:
Amazon.com: Silverstone Tek FT02B-USB3.0 Aluminum ATX Mid Tower Uni-Body Frame Computer Case with 2X USB3.0 Front Ports Cases (Black): Computers & Accessories
I linked my case also because I don't know if this is a case issue - it is a pretty complex case with all I/O ports / power supply coming out the top (the PSU air intake is from the back, blowing out the top).
Here are the only 2 differences I can think of between day 2 (no issues) and day 3 (intermittent buzzing): On day 2, I plugged in the speakers for the first time while the computer was running - so day 3 was first startup with speakers already plugged in. Also on day 3, CPU core temps were on average 5-6 degrees lower at low load (averaging 23-27 celsius), whereas on day 2 they were about 28-33 celsius - I assume this is due to the thermal paste taking approximately 10-15 hours of cpu running time to work properly.
I have checked the fans - there is nothing interfering with the CPU or GPU fans. I have also checked for interfering cables, etc. - nothing is inside the fans (there are a couple nearby but nothing in the way or interfering). They are of course also very clean (brand new).
I would greatly greatly appreciate any help/guidance on this - I have put a lot of time, money, and effort into this and am really frustrated with this one problem. I'd also like some thoughts on whether this is putting my PC at risk, or this is just more of a nuisance that I shouldn't be too worried about.
Thanks everyone.
