Thermal paste change

[BlueFish44]

Hi
I'm writing to you using my dear macbook pro mid 2010. I managed to swap the 4 samsung's gb ram to 8gb crucial's one. Then I installed an ssd instead of the old toshiba hdd and now it rocks. Everything works fine, I don't anything heavy so why should I change computer? Anyway I manage to solve even the known kernel panic problem of this mac related to a too cheap capacitor apple decided to use... I installed windows 8.1 on it and I'm planning to upgrade to windows 10. Now I have two problems:
1- The battery is gone, I always have to use the pc plugged in
2- It reaches temperatures about 80 degrees. Should I change my termal paste? I have never done it since 2010, I'm pretty scared I could damage the pc doing it, should I?

Which part is reaching 80 degrees?

Will you be running macOS on it?

I run macOs on it but I don't misure the temperature with it. I misured 70-80 using windows 7. Now I don't have it anymore and on windows 8.1 the temperature are about 50-60 without stress. Is windows 8.1 less heavy than windows 7? Anyway I'm talking about cpu.

Is this a 15" or 13"? The 15" base model has a core i5. The 13" has a Core2duo.

Maximum temperature for the i5-520m is 105 Celsius.

The Windows Boot Camp drivers have terrible fan control. If the max temperature is 70-80 that's still 15-20 under safety limit.

I would personally recommend using liquid metal as a replacement, thermal paste as a limited lifespan before it fails and cause thermal issues, liquid metal does not

While I'm in videocall with 20 people these are the values:
GPU about 70 C
CPU 70-85 C

Under stress with a 4K video:
GPU 74 C
CPU 94 C
