Very High Temperatures with my iMac

i have a 27 inch iMac and the last few days is getting really really hot. I installed temperature monitor and I saw a temperature of 80 degrees of celsious!!


Is it possible to be a software related problem ? Or a hardware ? Any suggestions on how to solve this ?

iMac, OS X Mountain Lion (10.8.4)

Guys I finally did today the ASD. Here are the results. Nothing wrong with the heatshinks... Some Bluetooth error that I think has nothing to do with the high temperature...

Guys... I found it...!!! There is a problem related with the display of the iMac. I found a similar thread here...


https://discussions.apple.com/thread/3484579?start=0&tstart=0


When I lower the brightness of my display the secondary heatsink temperature goes from 85 to 65 in less than 10 minutes! When I increase it back to full goes back to 85+.


Also I did an SMC reset that seems it helped a bit. After the SMC reset the fans work better. I hear them more alive.


Thank you all for your replies.

I'm very concerned as my stats are way higher than everyone's, and I have no monitoring of my fans, as the Help pages say you need another program "Hardware Monitor" to get those stats. In fact, I never hear any fans coming on or off, on my iMac. Could that be why my temps are so high? I always run an external fan pointed towards my Mac, because of my concern...


Here's my current listing:
