    Hi,

    My mac is overheating quite easy and really trying hard with the fan.

    I have done a little research and I don't have any print jobs. I have checked my activity monitor and i'm 72% idle and I also have 42 gigs free.

    Running lastest everything, snow leopard etc

    Any ideas?

    It would be nice if you could provide more information, like what exact Mac model you use and what the temperatures and fan(s) speed are.

    You knowing what the fan speed but not the temperature is, makes me assume you have some kind of fan control software installed.

    If that is the case, look at the settings of that application.

    Btw, it's summer in the northern hemisphere, thus computers get a bit hotter.

    If you don't have a fan control software, either try SMC Fan Control or Fan Control.

    I would advise against it, as the MBP could come into contact with liquid.
    I once put an iBook into an oven though at 50-80°C, but I put many things into them anyway.

    So all in all, if the CPU gets hot, the fan(s) spin, especially if you may have installed some fan control software.

    You could try an SMC reset though.
