Hi all. Well, I am simply in love with this machine! I have a 3.06 24" iMac ( the previous model - 8800gs ) with the memory upgraded to 4gig. Currently I am still being blown away by the entire mac experience, and am in the process of learning all the little nuances of mac life. I do, however, have a question regarding my iMac's temperatures. In the old days of PC usage I had a machine that went POP due to overheating. Being old, grumpy and perhaps a little paranoid I grabbed the iStat widget so I could monitor my mac. The problem I have is that when I look at the temperatures inside my mac I have no idea whether or not they are normal! I was wondering if anyone would be willing to glance over them and give me a much more informed opinion that I am able to produce.! Here's the temps... HD: Macintosh 46 CPU A: 38 CPU Heatsink: 37 Airport card: 35 Ambient: 19 GPU: 43 GPU Diode: 50 GPU Heatsink 42 These temps are in degrees Celsius. The mac is not doing anything other than running Safari and Skype. Are they ok? Thanks for looking.
