    its wierd, its 60 degrees celsium and 2300rpm fans (without any smc fan manglers) just FRESHLY rebooted, and completely CLEAN install! without anything. odesnt matter if its 10.5 or 10.6.
    it used to be 44 degrees and 1800rpm fans! and 40 degrees with 2000rpm fans on 10.5. .

    Did you reset the smc? Were you on the 9400m and now on the 9600m? Do you see the fans ramping up as the heat increases?

    my MBP is not running any hotter or cooler since moving to SL

    I recommend using smcFanControl, a great utility had managing fan speed and temperature control.

    i have Fan Control prefpane, but on the OTHER system (i have dual 10.6 one is craptastically cluttered, one is fresh)
    the thing is, the cluttered one runs on 45 degrees just opened, while the fresh install on 64 degrees cpu.
    BOTH running 64bit kernel.
    its odd.

    Would recommend an SMC and PRAM reset and see if that helps.

    10.6 running hot

    Is your new install of 10.6 on your Express/34 SSD card?

    I've heard those cards run hot.

    Go into Activity Monitor>All Processes. Do you notice anything taking up a lot of CPU?
