m15 R4, Core Thermal Throttling after thermal Pad replacement at 60c Normal?

Hi guys,So I have this M15r4 with i7-10870H with Nvidia RTX 3070 with 32gigs of Ram and 4K OLED for about 2.5years now and have been using this laptop normally for occasional gaming and browsing the internet..but recently it became very uncomfortable to use the laptop on my lap for normal browsing stuff and for gaming I use it on a cooling pad,but I felt the laptop was getting very hot in the bottom and well as on the keyboard sides for just normal work loads so I thought it’s time to replace the thermal paste and clean the fans for any dusts so went ahead and got the Noctua NT-H2 Thermal paste after a lot of research online.

And in the process while taking the heat sink off from the motherboard I saw a thermal pad that just fell from the heat sink..upon close inspection I could see the some of the grey thermal pads were very hard and not soft like some other thermal pads and were crumpling and were breaking off when I tried to touch them,So I decided it’s time to replace the pads as well and after researching figured GELID GP-Ultimate to be the best out there so got the pack of 120x120 diameter with 1mm thickness,Where the thickness used by Dells thermal pads for all sections on the heat sink when I measured came out to be 1mm for all,not sure why were all the pads had different colours even when the thickness was the same 1mm throughout.

I carefully measured and cut and replaced all the thermal pads with the GP-Ultimate which god took me close to 1 hour just to measure and cut them one by one,I am attaching the before and after pictures of the heat sink thermal pads below kindly check and tell if I did a decent job.as this was my first attempt in replacing thermal pads,where I have replaced thermal pastes a lot.I also Hope this helps anyone who wants to do the same as there isent much information regarding the thermal pads size of Alienware m15r4 online.

So coming to my main question of this Post.Initially I dint measure the temperature of my laptop before repasting and replacing the thermal pads becoz I knew it was overheating so dint bother to check,but after replacing the pads and the paste I could comfortable browse the internet and use my laptop for light work on my lap,so was very happy but out of curiosity I though I would check the temperatures to see if everything is normal and I dint mess anything up.I ran few games AC Valhalla,GTA 5 and to make it clear I was using a cheap cooling pad with 5 Fans for gaming and had also kept the TCC offset to 15 in the the bios to keep my temperatures low and I was gaming for like more than 2 hours straight with fan profiles set to Performance Mode and the Ambient room temperature was around 24c and when I checked the temperature the max temperature was 90-92c for CPU and 70-80c for GPU so temperature seems normal here..Correct me if I am wrong.But the CPU showed “Core thermal throttling “ for all the cores even when the temperature were way below 100c and when I closely noticed some of the cores randomly shows throttling for few seconds at even 60c attaching all the sensors screenshots below.

So was wondering if this is normal for some cores to randomly throttle at random temperatures or did I really mess something up during the Pad replacement and that’s what is causing this? I really need your opinion as to if it’s safe for me to use my laptop normally and for gaming…also I am really sorry guys if this post is really very long but just wanted to give you detailed explanation for you pros out there to understand my case really better.
