    Unhappy Why Does my 2.2 Ghz Macintosh Laptop Run at 90 Celcius on Idle?
    The title explains it all above. The mac is a 2.2 GHz Intel Core 2 Duo, made back in 2005. Please help! I am afraid of melting the parts inside my laptop!

    *Oops, I meant to type Celsius, but had a little typo.

    I cant tell you for sure what the problem is but I can suggest cleaning out your fan and checking out smcFanControl 2.2.2 released Hope that helps

    dang almost sounds like a heatsink not completely touching the die on the cpu. and at the temp its running at SMC wont help you as the logic board built in has fan controls to automatically put it to full speed at that temperature. Your cpu is good to 110*C but I wouldnt even try to do anything if your idling at that temp. SMC fan control will help to determine if your fans are actually running or not and go from there. Not sure if your fans are running as you did not specify.

    Parts won't melt inside your laptop. The machine will hang or shut down before any kind of damage would ever happen.

    Most likely you've got a runaway process (check Activity Monitor and sort by CPU) and/or the exhaust vents are clogged with dust.

    SMCFanControl shouldn't be necessary, the fans are thermostatically controlled.
    Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

    Compressed air dude. Sounds like your laptop is old and been building up grime inside. Get that dust out!
