what you need to do is what i saw in a cop car once. they have the laptops mounted on the console between the passenger seat and the driver seat. well anyway, he had a little aluminum duct going from one air vent (completley covering the air vent) into the side of the laptop. he'd obviously modded it a bit, but it makes sense, and it would definately keep the computer cool.
it doens't matter how hot the laptop/desktop gets when you're not in the car, but as soon as you get in a hot car, you're going to turn on the air, and when you turn the laptop on, air will be blasting through it. therefore, it will stay cool //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
