    I found a nice little program that allows me to speed up the fans if I want to. Im wondering if it's worth speeding them up just a little to get some of the temps down. Here are some of the measurements right now with fans being controlled by the system not the program:

    CPU A&B: 95-100 degrees
    Northbridge: 171
    All HD bays (Filled with a HD in each): 85-90
    Memeory banks (most filled): 100-125
    Memory modules: 150-170
    Hard Drives: 90-110

    Are these good/bad/normal?

    Would you suggest upping the fan speed a little?

    These are all normal. I wouldn't worry about the temps too much. As long as its not 95 degrees in your room, you'll be fine.

    To get a better idea:

    - what system do you have
    - what is the ambient temp
    - what memory modules do you have (size 1GB DIMMS, 2GB DIMMS?)
    - what are your fans running at now?

    If you want, iStatPro widget will list all this....take a screenshot of the temps and fans section and post.

    The memory that's up over 170F and the Northbridge that is over 170F are a little high...in my opinion.

    I'm on a 2006 Mac Pro with 11GB of RAM. I notice that setting smcFanControl to put the CPU fan at 600rpm (up 100rpm from the standard)...which also increases the exhaust automatically to 700rpm does wonders. Keeps the temps within reason.
