Computer Problems

then I'd make sure it is running. You can't run a modern computer without a fan.

Can I put 2 fan into my CPU?

Mine fan does run it just does so very quietly... I had to find out by putting my hand over the vent on the back...Is it a good thing that I can't hear it?

Yes, it's much less annoying that way...My fan started buzzing when I left it on for 3 day straight with the monitor off...
