Hi everyone, I'm new here so please excuse my ignorance but I was wondering if anyone could help me. About a year ago my computer started to make a rattling noise, for ages I didn't know what it was and took it to a number of repair shops. Eventually one of them told me that it was a ball bearing that had gone in my PSU. They replaced it and that was ok. However the new fan and psu was extremely loud so I took it back and they replaced it with a new one which was much quieter. Cut to today or rather this week. The rattling has come back, I am hesitant to believe its the same thing as its only been a year since the PSU was replaced...another thing thats happening is sometimes when I turn my computer on the fan on the psu is extremely loud, it sounds as if its speeding up, after 2 mins it goes quiet and slows down. I was worried that maybe the psu and fan was failing so I took some advice and downloaded speedfan and this is what it showed me- I have one fan (which is weird because I have the psu fan and a small case fan, shouldn't they both appear on this?) The fan1 was doing 2163 rpms my gpu was 65c temp1 was -55 temp2 was -55 temp3 was 39c HD0 was 33c Core was 59c ambient was 0c are these bad temps? can anyone shed somelight on this for me? Thank you
