Peltier effect cooling device

[TerminatorX5]

I have this question on more specific forums, but no answer (cell phone forums)...

Has anyone here ever tried or actually used PELTIER cooling devices to cool their cell phones (or other electronics)?

I am testing an Android phone, and when I load it up with Navigation, Pandora, and whatnot, it is "drinking" a lot of juice and starts to overheat to the point that it stops charging and drains the battery within an hour... placing the phone in front of AC vents going full blast MAX, cools it down...

I was thinking about using a peltier cooling pads on the back side of the phone cradle, which i will anyways, but I was wondering if anyone already has/had working experience with those...

The peltiers come in several wattage flavors, from 30W all the way up to 300W (of "cooling" power)

thanks for the input...
