some weird noise

post #1 of 10
Thread Starter 
I finished building my PC yesterday, I installed 2 extra case fans, one on the front, one on the side, they don't seem to be making any sounds, but I keep hearing this weird noise from the computer, it sounds like a fan grinding, I'm afraid it could be either the back fan (was preinstalled in the case), or the CPU fan! Which is dangerous if I am not monitoring temps, so what do I do and how can I be sure? (Stock cooler btw)

This is my first Quad core, let alone I have never had a dual core, bought this from some money I won, so you can understand I value this rig A LOT.

Unplug the fans one at a time. You'll be able to tell which one it is. Do the cpu fan last.

Hmm... I was thinking of opening the side of my case just to find out the source...

What i do is just open up the case and stop each fan with your hand (If its not spinning to fast) then you will be able to find the source of the noise

You can also touch and pressure the center of the fans for a short time to stop them and hear if the noise gone. It can also be the case/screws/plastic parts rattling

My brother said it was the CPU fan! Am I doomed or at least will the CPU get damaged if this thing turns off without me knowing?

Usually programs like HWmonitor or OpenHardwareMonitor show the cpu fan's speed. Check if it's too low or not. Or post a screenshot here.

Check your temps with hwmonitor... Is it an aftermarket cooler? if it is just stick the original CPU cooler back on..

You hadn't done that yet? Not to be rude, but how are we supposed to tell you what it is if you haven't leaned over and investigated for yourself?

Very true. Come on man. 2k posts and you don't know the basics? What have you been doing on the forums the whole time? >.>
