Portable 13" Macbook Pro Cooler

I recently bought a 13" Macbook Pro for school, and need to find a portable cooler for it (I plan to be doing some gaming during study hall). I had a Zalman NC2000, but it doesn't quite fit in my backpack. Any suggestions?

 

This is what I use.
Cooling | AWE45US1 | by Targus

Since the 13" MBP has no ventilation inlets on the bottom of the unit, traditional fan type coolers have a demonstrably lesser effect than a contact cooler that draws heat from the unit by conduction.

 

Do you notice a significant decrease in temps?

 

even pushing my MBP 13" hard, just the internal fans keeps it nice and cool... I have a couple of nice coolers for laptops and they really make no noticeable difference in temperature.

 

I never did any scientific testing to determine the measured drop in temp. I just noticed that things were getting a little toasty on occasion with certain intense gaming.

With the pad, the discernible exterior and topside temperatures were markedly decreased, and I have seen nothing approaching a worrisome temperature on my istats readouts.

It seems to work quite well for what I wanted it for.
But Doh is right, the 13" MBP is quite adept at keeping internal temperatures well within operating specifications using nothing more than the stock cooling system on factory settings. The pad is for keeping the exterior temps controlled and comfortable. As it performs this function of heat conduction, it can't help but remove BTU's from the system as it does so.

 

If you prop up the back of it with 2 packs of cards, it'll drop the temps by a few degrees.

 

Right now just listening to itunes, and browsing the web the aluminum is cool to the touch (38 degrees celsius), but after playing about an hour of some games on it (MW2, and GTA IV) I rebooted into OS X and my temps were about 60 degrees celsius, with a cooler. Do you think passive cooling (heat pad) would be better then my Zalman?

 

I think 60 degrees Celsius is fine, I run SMC Fancontrol at max in OSX and Starcraft 2 puts my 15" at 65 degrees Celsius. I think your fine until you hit 100 degrees Celsius. I think its 105 before it throttles.

 

running maxed out with the fan high, i can push it up to about 75 to 80 ... 60 is nothing. Mac operating temp is listed as 105. My older 2008 unibody can hit 100 easy with the 9600GT enabled, thats the one i had originally bought cooling pads for, but the newer 2010 MBPs run MUCH cooler. I never boot into Windows though.

 

Good to know, I actually bought the mac specifically because I've come to dislike windows more and more... I'd heard great things about OS X and after buying my iPod Touch and iPad I'd come to really like Apple. It was a nice surprise however that I could boot into windows, and actually have a machine that could play games (ohhh the possibilities for school ) that is the only time I boot into windows.
