I have the program listed above. My idle temps are in the upper 30's to mid 40's for both graphic card (m8600gt) and cpu (1.8). I bought a cooler with my laptop so when it's on the temps might reach 60's C during a game. Recently, the power cord (USB) has become loose due to thin wire gage. If unchecked, I have seen temps reach 89C based on history in said program.
I would recommend a notebook cooler, store-bought or homemade, whenever possible. True, they are a bit clumsy for a classroom or business meeting, but on a desk one won't notice and actually are a bit more comfortable on a lap. Also, as many have noted, the air space alone is often enough to keep things in check even without being powered up.
