Not bad at all even when on full - if you have sound up or headphones on you won't even notice. The one thing that does bother me though about the fans is that sometimes they repeatedly go on/off in rapid succession over and over and over. I think whatever game is running must just be RIGHT at the thermal threshold so it keeps going under/over and triggering the fan to turn on and then shut off. I wish in these cases it would just switch on for good and stay on low rpms instead of all the on/off.
Try using the thermal limiting feature in the right-hand battery menu. Any game I’m playing, I bring it down as far as I can without unacceptable impact to performance. Often I find that I can set it to 7-9 and the fan goes nearly silent without any major performance impact.
