Croaking noise from pc and no hard drive

[Gabe3]

I got this croaking sound thats coming from my PC, it seems to happen during and after playing fortnite. The hard drive is unplugged completely. It sounds like a dying hard drive.

Maybe a strange form of coil whine?

get a paper towel tube and start listening for where is coming from.

Fan with failing bearing?

It would make sense that there would be a correlation with your game-play, since most fans these days use some form of speed control based on temperature, and obviously playing a game will raise your temps. Just hope it's an easy-to-replace case fan, not a proprietary fan on a GPU heatsink.
