I just got this and the top back of the unit is very hot, almost too hot to touch. Is there supposed to be a fan running, or is it only a heat sink?
There are actually 3 fans, with speeds between 900 - 1400 RPM. Please download, install and run iStat Pro to determine temperatures and fan speeds.
Yes it is normal I have the 27 inch and was really concerned at first.
The heat is leaving via the casing, the casing is basically one big heat sink. It can get so hot you can barley touch it, try playing a game for a while you could fry an egg on it!!!!
Don't worry at all.
