Overheating? Developing for TF2 while playing? Otherwise doing stuff source doesn't like?

I get wireframe now and then from alt tabbing and messing with gcfs and map loading and whatnot, but no crashes.

I got the same last night, mostly on the gold displacements while I was spectating an empty server, waiting for a slot on my normal one to open up.

You know you don't have to go in game while waiting for a slot to open up right?

I do, but I took the time to check out valve's way of doing things, so that my own map would look better. Specifically I was looking at the building at the end of the 2nd round, how on top you can see through and stuff.
