Pretty self explanatory. There's lots of threads on coolers. Of all the threads I've seen either it doesn't work or it worked 10 degrees F (which isn't really that much is it?) I primarily use my 17" brand-new uMBP for FCP and other CPU intense applications. Using compressor right now and CPU is at 85 degrees C (where it will stay for the duration of my render, which is 5 hours). In threads I've heard people say you should worry about anything over 80 degrees C but they must be just surfing the web. There's no way to keep it that low when using 90% CPU. Heck, my fans aren't even above 3500rpm. Still, I have my MBP sitting on top of some empty DVD cases to allow more air underneath and keep it off the table it makes hot. I took off my moshi clearguard to let the keyboard breath. If I had a personal pocket fan I'm sure that would be just as good sitting it under the MBP raised by wood or whatever. I wouldn't mind a stand to bring it to the level of my 24" Dell.
