I guess it depends on what people's definition of "warm" is. I typically shoot for temps no higher than 50-60*F above ambient max. So, if it's 80* outside, 140*F is the max I like. For some, this is just warm. To me, that is hot. Don't forget, electronic components have a temperature derating factor; the hotter it gets, the less current it is rated to pass.
