    I was just chillin, and my computer starts to output maximum fan power for no reason. I wasn't even touching it and it started to blast out. I've checked out task manager and the cpu isn't over-utilized, and neither is it hot...I held my hand over the fans and they were blowing chilled air. It's scaring me because I have no idea how it happened, since it just happened while it was on. I even updated the UEFI, but that had no effect. The computer works as fine as it did before, and the only time the fans stop is when it's off. Before you couldn't even hear them and now it's really and scaring the crap out of me... It's a Windows 10 Dell XPS 8910 desktop. Here's a video.. https://goo.gl/photos/nNE3bxiYhewJvi9Y8

    Have you checked the temps of the computer? Made sure the inside isn't full of any dust, esp. on the CPU heat sink/fan?

    I bought way too recently too already be experiencing any dust of that volume. I'm also sure it wouldn't be due to that, since it starts on max power as soon it powered on, I mean that seems like too much of a drastic change, going from quiet to max power like that...

    Was it a case fan? CPU fan? Graphics card fan?

    Hm.. Strange. I opened the case up and it seems that only the cpu fan and top case fan are running... The power supply fan and two other case intake fans are not running... (I do not have a video card fan). Now first the first time, it stopped for a second or so, then powered on and off again before turning all the way on. Could it be because I opened the side of the case allowing for more airflow and ultimately more room for cooling?

    Could be, but I never expected a Dell to have that kind of temp hardware. The power supply is pro active so it's going to be on and off.

    What do you think could be the problem relating to the to the other fans not turning on?

    Could be a bad fans, yes they do go bad. I have had brand new ones not work. Check theyre seated fully into the board. Unplug a dead one and plug it into a port that you know has a functioning fan.

    Hey, thanks for your help, the problem seems to have after I shut it off and waited a little bit. I'll keep you posted if problems arise again!
