This morning, one of my fans started making a pan noise, after a few seconds, it stopped, restarted for 2 seconds before stopping again. Since then he has only done that. my computer was no longer under warranty so I went to the Dell site to see if I couldfind replacement parts.. but it seems Dell doesn't provide replacement fans though site. Has anyone had a similar problem and, if so, what are the solutions? thanks in advance
