I noticed that my new build has been making a buzzing sound. It only occurs when starting a GPU intensive benchmark. Running prime95 has no issue. When running superposition or just playing a game, either my CPU or GPU block starts making a fairly loud buzzing noise. It start immediately after being stressed. It's very hard to tell whether its the CPU or GPU block but its one of them for sure.

I don't know how the blocks could make these noises, it really makes no since. It's not rattling like the pump speed is high and causing standoffs to rattle, its more like a phone vibrating on a table but faster. I don't feel any significant vibration however when touching the blocks.

They could not find the solution and he RMA'd the video card and it stopped. I can't RMA this $1,600 card because i've had it a year, so its not looking good for me.

The noise is the only issue ive had thus far and everything is working fine. Will I be safe using this card or is there going to be a problem?

Any ideas would be appreciated.

Edit: It seems like it could be coil wine, but this card never had issues until I installed the new custom loop.

PS - CPU - idle = 26c
load = 77c (Prime95)
GPU - idle = 26c
load = 54c (Superposition)

Solution
I was going to say it might be coil whine before I got to the part where you added the edit. If it is, coil whine generally won't cause you an issue other than being annoying.


I'm guessing thats the issue. I'm very happy with my first custom loop! The only problem that I had with it was the fact thats its so much quieter that I can finally hear the coil wine of my GPU, lol. Hopefully it all lasts a year or two.
