    I looked around the forums about my question, but couldn't quite find the exact answer I was looking for, so here it is:

    I have a 13 inch MBP (unibody), which when I'm at home I plug into my monitor/mouse/keyboard/other external devices and put it into "clamshell" mode. However, from time to time, I have overheating issues. I know that with the unibody design, a lot of the venting comes out of the keys (or so I was told/read) and I could occasionally open up my MBP to let it "vent" out, but I'd rather just get a cooling device to throw under it and keep it cool all the time when I'm at my desk.

    I normally don't have any hot/overheating issues when I'm using it by itself, I really think its just using it in "clamshell" mode is what is causing it to heat up occasionally.

    So if anyone has run into this problem, or knows of a good cooling device for the 13inch MBP to just chill on my desk, please let me know!

    What "overheating" issues are you having. Most likely your overreacting and just creating another temperature thread.

    Overheating as in 6000+rpms from my fans, noticeably hot to the touch, and the CPU spiking considerably.

    If anything my MBP vents even better in clamshell mode, as the bottom of the screen isn't blocking the slit....
    :confused:

    Going to need some istat temps or something, your fans being 6000 and your mac being hot doesnt really go far for anyone helping

    that is just after an hour of being used though, running a little hotter than when i have it out and open, but not temps from when it will overheat, i'll try to grab another shot of it when it happens again and post that.

    That is a pretty normal temp... I get that just having a few safari tabs open and with skype and mail open, if that is as hot as it gets you're being paranoid. I mean sometimes I get temps at like 85 just watching flash video, but that is also normal. Don't worry about it.

    Heat naturally rises out of the keyboard area. Also, you are reducing the surface area available to ambient air.

    While idling, there might not be much of a difference. During peak however you will probably notice temp differences.

    I recommend this cooling laptop pad enermax Its simply the best, great design, one huge fan to draw cool air under the laptop. Works great.

    Part of the problem is that when connected to a larger resolution external monitor, more heat is generated by the video card.
    Also, the unibody Macs are designed in such a fashion that the rear vent only opens when the screen is open, and gets blocked in clamshell mode.

    What I find useful is "tricking" the machine into only using an external monitor despite an open lid.

    I was looking at this one, the only drawback, for me, was the somewhat large wrist rest, since i'm really only looking for something to cool it while i work off my externals at my desk. its reviews on newegg are also a little low for me...

    The enermax is really designed to have the MBP on it, without you "using it" Its up high and the large front precludes using the MBP keyboard. Plus the bottom is designed in such a way, that's not really usable on your lap, just on a flat surface.
