Q: My MacMini3,1 Is over heating

Ok yesterday My mac Mini started over heating. I noticed some weird Black flashing on the screen when It froze. then it did the whole screen saying to restart. I left it un plugged but from what I read up its over heating so I opened it up and Tried to blow it out that way. (Got more dust out) is there any better way to get it to stop over heating. I have it elevated like 6 inches to help it have more air flow. Should I put a little fan aimed at it from below?

Late 2009 Mac Mini. I am on it now other then this its been a wonderful mac

Install a temp and fans speed app to see what is happening. Maybe a fan problem. I use

Those temps are normal and do not reflect overheating.
What is missing is missing unless you did not include is fan speed.. That should be to the left of the temperature window. See:
http://www.crystalidea.com/macs-fan-control/screenshots
If not present that would indicate a problem with the fan or its speed sensor.
Can you hear the fan? The fan may run at full speed with no working speed sensor
You can run Apple Hardware Test
Using Apple Hardware Test - Apple Support
You will need one of the original disk that came with the Mac

Well it was overheating but after I opened it up finally and blew it out I guess the problem was fixed. i was unable to properly dust it until now. So what temperature should worry me?
