This is ok?
On boot I got a message saying that the CPU was being throttled because it was over the temperature threshold. IIRC the BIOS said that the CPU area temperature was about 80 C.
BING! BING! BING!
You said you'd opened the case - did you clean the heat sink on the CPU?
Not lately I haven't, but it seems that I will soon.
Can you turn the system on with the case cover off, and see if the fan on the CPU is running?
Yes.
One thing I've never done, or thought of until now, was whether the thermal grease between the CPU and the heat sink had dried out. If it's running hot, that's a possibility, so you might clean that off and put on some new (a buck or so at any computer parts store). Doesn't need much - the force of tightening the heat sink will spread it much farther than you expect it to, and you don't want it coming out the sides.
"the force of tightening the heat sink" frightens me silly, but I suppose that would be better than a dead CPU fan. My recollection is that that does not come off.
