I did a few small tweaks and have screenshots of them below. With barely any other alterations, not even a laptop pad, the temps reached a max of 71 for CPU and 67 for GPU when playing Ghost Recon Wildlands (capped at 60 FPS though since my screen supports that at max).
Earlier it used to be 60-70 with peaks to 80. Now its peaked at 71.
All my tweaks are visible in the screenshots - except CPU under volting - this is at -0.125v for cpu core and cache.
