    I used my wife's old MB Pro (2006, 2.0 GHz Core Duo processor, version 1,1, A1150) to watch a couple of TV shows last night and after 40 minutes the temp was a staggering 75 C (about 170 F). I have smc Fan Controller installed and at some point in the past I cranked the fan speed up to 6000 RPM b/c she complained about how hot the machine got. I use a version 4,1 MB Pro (early 2008, 2.5 GHz SR) and also use smc Fan Controller and keep a close eye on the temp due to the GPU issue on this model. Even when watching video I never see the temp rise much about 45 C (about 115 F) (at 4000 RPM fan speed).

    So this morning I took apart the wife's MBPro, cleaned the fans as best I could and made sure they are both running. (the fan blades were coated in dust on the leading edge, but nothing was really blocked as I expected). Now I've got it sitting here playing video and the temp is up to 60 C (about 140 F) after about 30 minutes of video.

    I guess I'll replace the fans, but I don't know what temps should be for this model. It seems a bit hot and I don't remember it being this hot when I used it. Is this something to worry about? Should I start shopping for a new machine for her?

    Here is more temp info:
    CPU A temp diode 60C (142 F)
    Enclosure bottomside 35 C (95 F)
    Graphics Processor Chip 1: 52 C (125 F)
    Graphics Processor Heatsink: 58 C (136 F)
    Main Heatsink 1: 39 C (102 F)
    Main Heatsink 2: 41 C (106 F)
    Memory controller: 42 (109 F)

    Normal. There are dozens of threads about this.

    that's completely normal. in fact, i would expect both of them to get hotter if you weren't cranking up the fan speed with smcFanControl. i don't bother because i trust apple's built in fan control.

    Mobile silicon can run a lot hotter than desktop stuff. It is like a GPU that can handle more than a CPU on Desktop in terms of heat.
