So at first I though my cpu fans were making a lot of sound but it turned out it be my psu fan. The psu fan is really loud and makes a annoying rattle sound which is very noticeable while gaming. This happens after I cleaned it with a air compressor before that I didn’t have this problem. Also my hdd is really loud and I’m not talking about those writing and reading sounds every now and then but the spinning sound. It’s probablt around the noise lvl at a case fan on over a 1000 rpm. When I unplug it my pc sound pretty silent expect for the psu of course. Should I back it up or is this normal for a hdd?
