I have no tested H.264 acceleration, although I plan to soon. It should be much cooler than whatever temps I get from running benchmarks. Most hardware is built to withstand 150F easily these days. It should be no problem at all. I have a feeling Hardware Monitor is not giving the correct temperatures, but NOTHING else seems to be able to read from the laptop's sensor. Either this new chipset is radically different than any other AMD chipset or they are using new sensors. When Idle the laptop is very cool. As I said, the only hotspot is isolated to the top right corner near the exhaust. The bottom of the laptop remains only warm, with no heat at all coming from the keyboard. During HD tune the right palm rest got a little warm, but that's due to hard drive thrashing, which does not occur on normal use. Because the exhaust is on the corner, you can avoid it entirely in tablet mode. It's not much of an issue at all. Screen is grainy, where whites are VERY grainy and darks are much less so. In the daylight, the screen is pretty much unusable in tablet mode (direct sunlight). The viewing angles are decent in the vertical (above and under), bu the horizontal viewing angles are pretty bad. Luckily the tablet screen can rotate clockwise to make up for it. There's an option in the BIOS to have your fan on at all times. This was the default option for me. Check that this is the case for you. Otherwise ask for an exchange. It shouldn't reach those temperatures normally unless you're benchmarking.
