    Hi there !

    Found a nice way to even improve the great cooling performance of my nMP.
    Just take a look at the picture.... It´s just an "Arctic Breeze" USB-Cooling-Fan.

    In regular desktop working mode (writing, browsing, playing music, download, copy etc.):
    CPU: 7-10C less
    GPUs: 3-5C less
    SSD: 3-5C less

    (air temp 27-30C)

    Might be less good at your home but it might be worth a try, the fan is quiet cheap.
    Just one thing is important: The Breezer has to be placed as near as possible.

    Cheers !

    Doen't the Mac Pro fan suck air through the case? Your desk fan is just blowing the air thats coming out of the top?

    Couldn't you just use software to speed up the Mac Pro fan?

    Why should I ? It´s working and that´s all that matters. I´m happy with it.
    Increasing the fan speed increases the noise level, too, and I hate noise.
    The Breezer is nearly unhearable, which is much better.
    You can try or leave as anyone else, it´s up to you.

    Don't have a Mac Pro, just wondering how this physically effects the temperature.

    Well, two effects come to my mind:

    First, the warm air coming out is blown away quickly which might speed up the bootom up airflow.
    Second there might be some top bottom effect leading to a more homogenous air mix and therefore more effective heat absorbance ? Might be rubbish ?

    Third there might be a synergic effect of both effects ?

    Or maybe it´s more useful here than elsewhere since the nMP stands under the pitch of the roof and the air gets stuck there ?

    Don´t know.

    I was thinking you could also use one of those laptop cooling stations to sit the nMP on. They blow warm air up, and since the nMP has it's intake on the bottom it would be get a blast of cool air all the time.

    I always found Apple leaning towards the conservative side when it comes to revving up the fans (my MBA gets uncomfortably hot with any length of CPU usage) and I use smcFanControl ( to lower the temperature.

    This setup made me laugh for a bit :) in the past, I've also tried a number of things like that, such as putting the notebook on a strip of metal, using a notebook cooling pad, etc. but even off the shelve solutions of well known brands only lowered the temperature of a mid-2010 13" MBP only one degree.

    If the measurement is correct and the temperature is really lowered by the amount mentioned, this setup is remarkably effective.
