27" iMac running a temperature!
My 2010 iMac 27" has started to run very hot to the touch, especially in the top right hand corner.
Is this a known problem?
Is there any software available to check whether the fans are running correctly?
The only perifferals attached are: A second screen connected via a thunderbolt port and two Lacie Thunderbolt (independantly powered) drives.
Thoughts and advice would be welcome.
