    i wouldnt think so. but it is possible, and because its black it might retain more heat then a lighter color so it is possible

    Covering the backlit logo? Aesthetically unacceptable. Kinda like buying a Mercedes and cover the tri-star.

    They might cause the notebook to run slightly warmer, but it would be nothing to worry about.

    I have plans to cut out an apple logo :) , I couldn't afford the ones with the apple logo already cut out LOL

    Unless you're using your laptop out in direct sunlight, the color of the case won't make a difference in the heat of your laptop with the case.

    As far as for the OP's question, you should be fine. The cases do raise the temps a few degrees, but nothing that would be dangerous to your mac.

    I have the Speck Hard-Shell case (clear) and no problems so far.

    That is so weird. For me that is the only reason I would do it. I hate running around as an advertising pillar without even getting paid for it. The only place I would put any sticker is over that Apple logo so it disappears.
    Aesthetically I think that would greatly improve the entire piece.
    Than again I prefer clothes where there is no brand on it or the logo is so small it isn't in the way. I also buy a car based on what it can do and not the status symbol it carries around.

    I have both the speck on my old MBP and I have the Ipearl Mcover on my newest MBP, I would recommend either.

    RE: cases, heat, fans...

    Hi all,

    I believe that the majority of heat generated by a MBP is removed via the fan exhaust (based upon my own crude experiments with various cases). If this is indeed the case (pun intended), then as long as the case does not impede airflow in or out of the MBP, the case should only minimally affect the internal temperatures. True, a case probably acts as insulation for the MBP's case, but in this case the fans just increase their speed to move more air through the MBP and thus remove more heat via the increased airflow, keeping the internal temperatures roughly the same, with or without the case. It is only when the fans are already spinning as fast they are capable of spinning and the maximum amount of air is being flushed through the MBP that insulating the MBP with a case will have much of an effect on the internal temperatures. This is because only in this case has the ability of the fans's air cooling maxed out and thus conductive cooling through the MBP's case becomes significant and adds to the exhaust airflow cooling.

    ...just my opinion, of course...


    P.S. Sorry, I couldn't resist...

    P.P.S. To significantly affect the cooling of a MBP, you should lower the temperature of the air entering. Newton's Law of Cooling tells us that the rate of heat flow across an interface depends upon the temperature difference between the heat bath and the object, thus lowering the air temperature increases the rate of heat removal proportionately. And, of course, lowering the air temperature thereby increasing the rate of heat transfer from the MBP to the exhaust air means that the MBP's fan algorithm will slow the fans (i.e., the fans won't have to work as hard to keep the MBP at roughly the same temperature).
