Man......my mac mini overheats, I believe. If I do anything that is "labor intensive" such as encode a large file and so forth, it'll shut down. Currently, I'm encoding a 22 minute HD tv show. Here are the specs right now..... CPU A 178 degrees CPU A 209 degrees Ambient 128 degrees Northbridge 1 135 Northbridge 2 137 HDD 124 It's running fine right now. It's not enclosed in anything - it sits on top of the hutch of my desk. It's not up against the wall there's at least 8 inches between the airvent and the wall. I just don't get it. ONe day it got so hot, I cooled it in front of an ac vent before I could turn it back on and stay on. Otherwise, it runs just fine. It's a mac mini 1.66 intel core duo with 2gb memory. Bought it 5 years ago new from the apple store. Currently the programs that I have running is itunes, visual hub and safari. I just don't know if it'd be worth it to take it to a genus and pay what $200-300 for repair? plus, I haven't purchased snow leopard yet, so it still have 10.4 software on it. superdrive is shot, won't read a disc or anything, keeps spitting everything out....so, I don't know if I should get it repaired or just let the kids use it. But, I don't have an extra $799 lying around to buy another one. Advise?
