Blade Advanced 2019 on the Struggle Bus

I have the 2019 2070-maxq version of the blade 15. About a few months ago I started noticing some dips in performance in Valheim, chalking it up to possibly being the unoptimized nature of the game, it hasn't been too drastic until the past couple weeks. Anytime this system is under load (with multiple games or programs) the computer shoots up to 100c, and just starts really having a hard time. This is even with low graphics intense games or graphic/vid production. I just completed a reset and updating of all the drivers. The temp stops spiking, but I can't score over 5000 on Timespy. It was around 4500 right out of the gate before undervolting. Does this performance seem normal for this series, I was getting 6800 level out of the box last year.
