17 R5, overheating

Hi , i have an Alienware 17 R5 with a 1080 and a I9-8950HK

I have to say this laptop has been aving problems since i bought it .

The thermals are just horrible. 

A year ago i repasted it and the temps got better , like waay better .

But recently i tried to use the laptop again, ( i have been using my PC for like half a year, cause i am home again) and well .. idle temps 70c and while gaming 98c

I repasted it again and what i managed to get is still 70c on idle and now its 90c when playing games. 

What's funny is that the games don't stutter . 

When i got the pc it was normal to see the CPU go into the 90c but not the idle at 70.

I repasted it again and no joke the thermals are almost the same . 

What should i do ? I used MX-6 thermal paste, the only thing i didn't change is the thermal pads cause i am not sure what to buy , but i am thinking that won't change the cpu temps.

Both fans work and i do have a laptop stand so the laptop has airflow.

When i repasted it now i also cleaned the fins and ventilators so no cloged vents.

I reinstalled windows and updated every driver, even got the Alienware command center to work.

I tought maybe it was a bitcoin miner and i did some scans, nothing found .
