XPS 430 PSU Fan & Speed issue
Hi, I've got my XPS 430 for about 2-3 weeks now. I've noticed that suddenly the PSU fan speeds up randomly. It doesn't matter if the comp is warm or cold. Interesting is, when I open the side panel it slows down. Even if I press the side panels it slows down. So my question is, are there some kind of a switch connected to the side panels? Why does the fan speed up, my XPS 420 didn't. Is there a quality issue with the PSU's for 420/430. I know I've asked the question before or am I just unlucky with the PSU's.
