Acer Helios 300 Temps go high periodically

shayan_48

Hi. 
It's been like 8 months since I bought the Acer Helios 300 (2018) with 1060 6GB and i7 7700HQ. In undervolted the laptop a while after buying it. Temps were ok without max fan (only coolboost was on). CPU was around 70-85 max and the GPU was about 60-70 max. A few months later, I started noticing a little bit increase on the temps without having max fan on. CPU 90 and GPU 77. I started playing games with max fan for a while and had good temps around CPU 70-85 and GPU around 60-75 (sometimes 69 max). Recently tho, even with max fan on, i'm noticing gpu temp going up to 80 and cpu going up to 90 in some games. Notice that i'm limiting the CPU clock speed to 3.2 GHZ and i'm getting these temps (except the first 5 months in which i had no limit on the clock speed). I started coping with the temps for a while until again the temps just lowered by themselves and back to CPU 70-85 and GPU 69-75 while. But then again a few days ago temps started going back up. Right now idle temps with external monitor connected are : CPU 47 GPU 46 and while gaming with max fan (Heavy games like CoD) CPU 80-90 and GPU 77 avg sometimes going up to 82. I'm all ok with the CPU temps but these temps on the GPU are new!  Here are my undervolt settings:
CPU: -116mv on core and cache
GPU: Curve based Hotel Hero's video. 
Any idea what might be causing the problem?

Maybe it is time to re-paste...?

Maybe It is but because of the coronavirus situation, Most service centers in my country are closed. Is it ok if I play with these temps for a while?

You can play, but be carefull not to fry the MB or the CPU.

I'm only worried about the gpu temps cuz they never have been this high. Btw what are good thermal pastes? (Other than kryonat cause I can't find it in my country)

@shayan_48 I recommended you to use 
              Thermal Grizzly Kryonaut
                                  OR
          Cooler Master MasterGel Maker
