Macbook Pro Retina Display Cooler

[death0525]

Since my mac book pro gets increasingly hot when im using it extensively (eg gaming), i would like to buy some sort of cooler to decrease the overall temperature. I was wondering if some of you can suggest some good coolers that functions efficiently and goes well with my new macbook pro.

how hot does it get with normal use in comparison to a similarly sized unibody screen?
