I repasted with a thermal pad three days ago
Did you use Honeywell PTM 7950? Some thermal pads are not that great.
What laptop model do you have? If you have a thin and light laptop with a 10750H, it is going to run hot. The 10750H has a 45W TDP rating. If the heatsink and fan were only designed to cool a 45W CPU then you will not be able to achieve maximum performance.
Your undervolt is working OK. There is no significant room to undervolt further without losing stability.
Edit - You can check the MMIO Lock box in the TPL window so you do not have two separate sets of power limits interfering with each other. I would also upgrade to ThrottleStop 9.6. If your cooling is only good for 45W, there is not much point in setting the long term PL1 power limit to 60W. Your cooling cannot manage 60W long term.
