A week or two ago before putting tara on a ssd, i used to run mint 18.3 on a hdd and after about 15-20 minutes of 0ad (relatively low spec game) gameplay the pc shut down, presumably due to gpu overheating.
So today for the first time i opened it up (it was not dusty, i have taken care of that several times before) and changed the 8 year old heat sink paste (was a sad sight) with the dot method.
Now right after boot the temperature according to nvidia x server settings is ~42 C but in a period of 3-4 minutes it steadily grows up to 65-68 C at about 1 degree per 10 seconds while only having the nvidia setting open (these are my start up programs, basically the same as a clean tara install, i even disabled the print applet https://imgur.com/26EF42B)
could i try anything else to reduce the temperature? maybe change some settings from nvidia x server settings? in the PowerMizer tab there is a Preferred Mode option set to Auto while it can also be set to Adaptive or Prefer Maximum Performance
EDIT: the heat sink paste i used https://www.aliexpress.com/item/3pcsx5g ... 38004.html
perhaps it's low quality
EDIT2: output of
