Corsair 750w cricket/squeal type noise during stress test?

post #1 of 4
Thread Starter 
I'm running P95 to stability test 4.8ghz, 1.35v. On and off I'll hear a noise that sounds like a cricket, or a faint light "squealing". It did not do this when I was stability testing 4.5ghz, 1.26v.

I took the side panel off and it sounds like it's definitely coming from the PSU.

Is this normal or am I really pushing my limits here, and should I back off? P95 is showing no errors. I have read people asking similar questions and they said it's perfectly normal for a PSU to make at least some faint squealing under heavy load. But I do not want to kill my PSU.

Temp is showing 64 currently load in the system tray (real temp).

Edit - It hasn't squealed in at least 10 minutes. I suppose the PSU was just under heavy load during that time of Blend and that's why it was squealing.

Its just some choke coil whine. One of the chokes in the psu must be vibrating. Its perfectly safe and nothing will die from it

Probably just coil whine, you are nowhere near the limits of your PSU. Your rig consumes around 300-350w at full pelt.
