Recent Issues With Razer Blade 15

I got a 2020 Razer Blade 15" Base Edition (model number RZ09-03287E22) maybe half a year ago and within the past month or so its performance has dropped rather significantly, I'm noticing a number of games that used to run perfectly fine are experiencing heavy lag. This varies based on the game, Shipbreaker and others are having consistent and constant slowdown while other games such as Vermintide 2 and Resident Evil Village are having spikes of lag every 10-30 seconds ending with the game speeding up, I suppose to "catch up" to where it should be. Changing the graphics very rarely has any impact. I don't know if maybe I've screwed up the software somehow or if something has gone wrong with the hardware but I'm rather certain given this computers specifications it should be able to run these things fine, and in fact did at one point. If anyone has any suggestions on how I might be able to fix this, please let me know.

CPU: 10th Gen Intel® Core™ i7-10750H processor 6 Cores / 12 Threads, 2.6 GHz / 5.0 GHz (Base / Max Turbo), 12 MB Cache
GPU: NVIDIA® GeForce RTX™ 2070 with Max-Q (8 GB GDDR6 VRAM)
Storage: 512 GB SSD
Memory: 16 GB dual-channel DDR4-2933 MHz (8G B x 2)

 

New somewhat small development, Darksiders III is having lag spikes as well without the speed up exhibited with other games. I was able to run this rather well even back when I had a 3 year old (as of when I first played the game in 2018) $400 dollar laptop so something definitely isn't right.

 

One of the fans has started making a grinding sound...

I'd like to point out that I take very good care of my laptop.

 

I like Razer a lot but I'm sort of beginning to question the actual quality of their products

 

Witcher 3 barely runs, never had a problem with it before.
