My Triton 500 "PT515-51" is Thermal & Power Limit throttling when under load

I'm having some throttling issues with my Triton 500 RTX 2060. I have tried undervolting in ThrottleStop with these settings, which did help slightly but not enough to eliminate throttling.

Here are my results testing under load with Cinebench r23 and playing a game like Cyberpunk 2077:

Thermal Throttling:
-As soon as I start the Cinebench multithreaded benchmark, the CPU temperature spikes instantaneously from idling at 40-45C to 90-95C. Then proceeds to keeps fluctuating every few seconds from ~75C to ~95C instantaneously, throttling when reaching the 95C prochot limit. The sporadic fluctuations are what concern me a little bit. I'm not sure if it's a sensor issue that is misreading temperatures. The fan speed doesn't seem to be fluctuating so I don't understand how it could keep jumping from 95C down to 75C and then back up to 95C. Looking at HWMonitor my Core#0 never exceeds 85C, while Core#3 is what keeps reaching 95C. 

-After roughly 5 minutes of playing Cyberpunk 2077 my Core #2 and Core #3 are between 94-96C indefinitely. While cores #0, #1, #4 and #5 fluctuate between 88-92C. I don't know if it's normal for cores 2 & 3 to be consistently hotter than the rest. Which is what's triggering the prochot limit and throttling my clock speed.

- I just bought some new Grizzly Kronaut Thermal Grease Paste which I was thinking of applying to see if it could help with my CPU thermal issues. I will hold off applying it until I hear some of your opinions.

Power Limit Throttling:
-While running the Cinebench multithreaded benchmark ThrottleStop shows that PL 2 is constantly triggering. To my knowledge, this laptop has a manufacturing power limit set to 45W and I don't think there's any way around it.

- While playing Cyberpunk, in HWMonitor the max power seems to reach 34W but Throttlestop will occasionally show that a PL2 limit triggered, which confuses me a little. This might not be anything to worry about though.

Notes:
CPU: i7-9750H
GPU: RTX 2060 6gb
RAM: 16gb

I bought the laptop 1 month ago and the laptop is by no means bad. The CPU clock speed is around 3900-4100 MHz, but when it throttles, it drops down to ~3100. It runs Cyberpunk at a decent framerate of 50-80 fps, with most settings set to Low though. The thermal throttling seems to be my biggest concern. I would like to know if the above testing results seem somewhat normal. Would just applying some Grizzly Kronaut Thermal Paste to the CPU help? I'm hoping that fact that solely Core #2 & #3 are causing the throttling isn't a big enough of an issue to need to send it in for servicing/repairs.

I appreciate all of the help in advance. Thanks!
