Temps are as the GPU-Z screenshot has it - quite comparable to a desktop GPU folding. The fan doesn't ramp up that much with GPU-only folding either. I can barely see any load on the CPU from the F@H core, unlike GPU2 on a low-end CPU which eats an entire core whether you're on ATI/AMD or nVidia.
Adding the CPU crunching into the mix though (2x WCG BOINC tasks, one for each "real" core) make the fan quite loud, say, on par with the Zalman VF-1000 cooler on full.
I can't get a good reading from my IR thermometer on the laptop exhaust, but it's on the back so let the person sitting across from me worry
