Grizzly doesn't do really well in laptop. I was using it before swapped to fuzeice and then Honeywell. Both sucks jn laptop thermal. Grizzly paste seems to pumps out after 2 weeks of use as that was the time where the thermal start to degrade badly.

I'll try and open the heatsink tomorrow and see how it fares after 1 month of use

Laptop tend to run at high temp vs desktop due to cooling limitation. Try honewell pad bro, u wont regret it. My current temp is 84 max with max fan speed+gt300 cooler and ambient temp of 33 playing farcry 6. Damn hot now the weather.
