Rattling sound in PC

[adamreeve01]

Hi, so i just built my PC and everything is working smoothly apart from one thing - every time i start the computer, i'll hear a rattling sound come from it. It doesn't stop either.

I looked online for a fix and have found 3 suspects:

Case fan

CPU heatsink

GPU fan

I'll try to summarise it: i turn on the PC, and about 2 minutes later, the rattling starts. I don't know how to fix it. Anyone got any ideas?

Open up your case and put your ear to it to know from where the noise comes from.

If it's the case fan then first try to tighten the screws a bit. In my AMD build, my case fan made some noises until i tightened it more. Though, when this doesn't help, it's probably the fan bearing. In this case, replace the fan with new one.

Do as Aeacus sayd. But also see if one or more fan blades are hitting a cable.
