Although the temp readings are quite warm, the unit doesn’t get very hot all at - its hardly discernable unless you’re really pushing it with 3d graphics or something.
Fan noise- well it is louder than my TR1mp was, and possibly my T1XP, and it’s on and off all the time, but at least the sound is of rushing air, rather than the annoying whine the original S series suffered from. Put it this way, I really got fed up with my S series, and Apple iMacs for their whiny fans, so I’m a bit of a stickler for them - my TX does not appear to bother me at all, even in a quiet room
