A notebook of this size is likely to spend much of its life on your lap, so ambient temperature becomes even more important than they would on a larger system. Fortunately, the T235 stayed incredibly cool through our testing. Even after we streamed a Hulu video at full screen for 15 minutes with the notebook on high-performance mode, we measured the touchpad, keyboard, and bottom at only 95 degrees Fahrenheit--well within comfortable temperatures. Even better, we didn't detect any warm spots on the palm rest, bottom, or sides. By contrast, the AMD-powered Satellite T235D got a bit warmer, with a 97-degree touchpad and a warm spot on the left side of the palm rest.
