    Hi all,

    At first I loved my mac (it's been about a week now), however installing Starcraft 2, and running very simple applications (watching a movie from iTunes for instance), running Parallel's, i'm noticing the system heats up quite incredibly, from 40 to 80-90 celsius.

    The strange thing is.. My fans are running around 2k RPM consistently, I've never seen them go much higher. (running iStats)

    Since I'm within my 14 days, I'm thinking of just returning the system, as tbh, I'm very worried at this point paying enough for the system as is. While I realize laptops in particular get "warm", I've used other systems and I've never had a laptop with heat issues such as this before.

    The only time it doesn't heat up to this extent is when i'm web-surfing.

    I'm fairly proficient technically, and something just doesn't seem right.. I cannot pinpoint it, but I honestly do not want a system where i'm nervous about heating issues..

    I've read a few threads concerning this, but are there any others out there noticing strange behavior of their new MBP's?

    RPMs are controlled based on curves that are stored in SMC. Apple uses very weird curves that only start to rise RPM when CPU reaches its threshold temperature. This kind of behavior results in very hot enclosure, high CPU and GPU temps but low noise.

    I strongly recommend you to use aftermarket software which will redefine SMC curves (I prefer old app called Fan Control - don't confuse with smcfancontrol) This is the only way to get proper thermal management. In my experience all unibody MBPs have enough cooling capabilities but their tendency to use lowest rpm makes them really hot under load.
