I just got my "new" refurbished Core i5 27 inch iMac this past week and so far I've been very, very happy with my choice to get this machine. However, I do have a few questions about the new rig. First up, how hot is this puppy supposed to run? Right now with only Safari open, iTunes playing some music in the background, and having just finished importing around 100 pictures into iPhoto my CPU is running at 49C/120F. Usually when I'm running some HD video in iTunes or videos using VLC I'll get a few degrees warmer. More importantly, how hot is too hot? When should I become concerned? I know I'm not using Firefox as that really got the CPU temps up there! Next, I've already got Windows 7 Home Premium (32-bit) installed via Boot Camp but I've not played with it much as I'm curious as if that might make it run too hot. Are there drivers in place to adequately keep my new baby running cool enough to not cook off anything important? Overall I love this machine! Today is the first day I've really had to play with it for any length of time due to my work schedule so I'm looking forward to putting her through her paces!
