protection cases and overheating

Hi everyone,

I've ordered a protection case for my HTC Desire from OtterBox. It is a highly protective case that is made of three layers. you can find more about it in the following url.

I've tried it before with a Blackberry Storm and it was excellent.

So since i bought my new HTC desire and I wanted to get the same for it. I already ordered it from Amazon.com. But now i'm reading all about the overheating problem that HTC might have. and i was wondering how does the cooling system work on such devices like the Desire? does having the device FULLY covered by the protection case, increases the possibility of overheating!?

Just received the shipment with my new OtterBox case for HTC Desire. And i tell you, its awesome.
fits perfectly on my device. and Thank God it was already on when my device fell off from a 1.5 feet high table onto the solid ground. the rubber skin around the hard cover gave some sort of shock absorption.

Thanks for the tip though
