Any cool running laptop that you can recommend ?

Hi.
Do you know what brand/model laptop does not get hot, even warm, that you cannot discern any warmth while running ? (not idling)
Thanks.

Laptops only really get hot when placed on a lap!!!! My Gateway ( previous laptop) NEVER got hot even when running for several hours.... My new laptop ( Samsung ) does get a little bit warm, but only when running UT3...

Both have never been on my lap, they have both lived on the dining room table...
