I got my 24" (2.8Ghz, 2GB RAM) Alu iMac at Christmas and I've dealt with it for 7 months but now I've had enough. The temperature this thing reachers, although it may be normal operating temperature, it's too hot! I sit here sweating in my room every night - even with a window open! Plus I don't like to open the windows as they let mosquitos, midgies, moths and other flying things in (I'm scared of flying things... :/) How can I keep my iMac cooler? It's just too warm, I can't keep my hand on it!
