Re: Optiplex 740. Fan runs full bore.
That's what I thought too, but I used an entire can of air just blasting this computer, and it wasn't even all that bad. It's a relatively new computer, but I think it's JUST out of reach of warranty.
I ended up whipping up an HP desktop for that user, so I can take my time troubleshooting this particular Optiplex... along with the other 30 desktops sitting around I gotta figure out.
