[SOLVED] PSU making rattling noise when gaming (not PSU fan)

[danel.tiitma]

I just built my first pc. At idle it doesnt make any sounds, but as soon as I launch a game, I can hear a rattling noise from the case, and as soon as I close the game it stops. I tested all the fans and none of them made any rattling sounds, then I took the PSU out of the case and tried again. The sound clearly comes from the PSU. The PSU fan isn`t spinning so I don`t know what causes the sound. I also tried the PSU both ways, but it didnt make any difference. (PSU is Cooler master Masterwatt 550)

the fan is probably touching the grill at speed., you have to understand a fan "floats on the shaft" when at speed it slightly raises itself from the base of the post of the fan so it is possible it is the fan still causing the noise. run game and then look/listen to fan I bet you will hear it properly now.

I tested the PSU out of the case, the fan wasn`t moving, but i could still hear the noise. Unless there are several fans, the fan is not causing the sound.

It has to be mechanical so look at the moving parts. Hmmmmm there are not many so should be easy to narrow down. Bearings fail, fans get out of balance due to even things such as dust.

I'm having the same issue, I'm using a corsair 1200 Watt PSU however, must be like a cap thing, bad news is I had this happen on my last psu aswell .. about 4-5 months later I got purple smoke and had to replace the power supply.

Suggestion if you haven't already done it is turn off power to pc. unplug power supply .. wait a couple minutes.. then use compressed air can to spray it out while powered off (can short circuit if you blow it out with it on/charge in any capacitors in it) I've had personally zero luck and just calling it a death rattle myself.. if you find out anything or resolve please post a reply here o7

I alreedy got a replacement PSU. I'm still not 100% sure what the problem was, but from some research I think it was probably coil whine. If it was coil whine it would not have damaged the system, but luckily I got the PSU replaced under warranty and the new PSU works fine.
