The cpu fan on my ASRock 330 has been making really horrible noises, and it's so close to the other heatsink (On some other component) that I can't remove it and fix it.

I googled a bit and found this page: http://asrockion.wiki.zoho.com/silencing-the-ASRock-ION330.html and this image:

Which looks similar to mine, but in mine the fan and the heatsink opposite it are even closer, almost touching.

So, I'm thinking about just unplugging the fan, but I'm not sure if that is a good idea?

I'm not that experienced with hardware, if I just unplug it and it overheats, will it just turn off?

Also any other solutions on how to remove it, fix it, etc is appreciated.
