I've been having some trouble with fan noise and somebody here directed me to some articles about oiling them. I read the articles and was all ready to do it, but when I opened up my PC I have no idea how to take the fans out and more importantly how to do it safely. I think the culprit of most of the noise is the power supply but I have no idea how it comes out and don't wanna be messing with it unless I know exactly what I'm doing. I want to oil all of the fans(there's 3 I think) so if you could have a look at the pics of the inside of my case I'm attaching and tell me how I should go about it, it would be much appreciated.
