Question What's this noise??

[James Blonde]

Got an occasional (every 30 seconds) hissing / sizzling (like water dripping onto a hot stone) noise coming from my PC. I fear that my Corsair AIO is failing and dropping liquid onto something hot, but not seeing any liquid or moisture inside the PC, and not noticed any increase in coolant temps as if I was running out of coolant.

How would you expect an 18 month old corsair AIO to fail?

Other idea was a bearing in a case fan, but I'd have thought it would make a noise all the time or rhythmicly in time with the spinning.

Kind of urgent given how close we are to Christmas and getting anything ordered / fixed!

Can post a video if that helps?

a video would help, as would full system specs, but there isn't anything in a PC that's hot enough to cause a sizzling sound from a leaking AIO, it would have to instant boil the water, ie. be at least 100 degrees, nothing will be that hot, and ifr it was dripping onto power rails inside your PSU you would be getting sparks and blown fuses. If you can't see any coolant residue on anything, or around the hoses, joints or radiator it won't be a leak, it could be the AIO pump failing, it could be fan bearings, it could be something else

unplug all the case fans (except the ones for your AIO radiator, run the PC with the side off so nothing gets too hot, see if you still get the noise
