My low use temps are pretty much like:
Low use (connected to external monitor):
CPU - 40-45
GPU - 37-42
Low use = watching YouTube videos, browsing this forum and such.
This is without any fans or laptop cooler. But I do have ThrottleStop on.
Earlier, same settings, temps were like CPU 40-50 and GPU 40-45.
Looks like something got updated in the bios that is lowering temps to good extent.
By the way, i pushed in version 1.19 released on Aug 10th (not 1.15 released on Aug 15th).
