Seeking Help What's this very loud noise?

[premierseiji]

After turning on my computer, there's a very loud noise. I took a video of it:

My computer works just fine, and the loud noise automatically disappears after 5 minutes.

But it's really annoying because it usually reappears again at random intervals.

Is it the CPU fan, GPU fan or something else?

Should I be worried?

Probably the SMPS fan? Anyway, if you know how to take out the fan from the processor and clean it, it'll help even if the sound is not from there. Else, if you are staying in a place where there is a huge computer market area, you could take it there and get it serviced.

Looks like GPU. Try to remove graphics card and run the CPU with display ports on motherboard

If sound still comes, then it will be from CPU fan
if sound stops, then GPU is in trouble

Fan sound may be from gpu,cpu or psu.
