It's normal for laptop GPU to reach higher temperatures because of the more compact circuitry, limited cooling possibilities and the restricted volume it's housed in. You can remedy to this by :
- Use laptop metallic fanned cooling pad to help cooling it and keep it at a good clearance from the surface.
- Verify laptops fans are clean and functional.
- VGA and CPU cooling might be linked together through same heatsink and cooling fan(s) thus making sure CPU is not overheating would help GPU stay cool as well.
- If you have control over GPU and/or CPU fan(s) through laptop manufacturer or software utility adapt it's curve to run faster when gaming.
- Use a third party software like MSI after burner to set lower temperature and power limit for your card to avoid reaching higher temps while gaming, and also to try adjust Fan curve if accessible to the software.
- In Nvidia control panel you can set overall performance options to favor adaptive mode, and might have to lower your 3D Nvidia panel game settings or in-game settings.
- You could use you laptop manufacurer dedicated utilities and/or HWMONITOR and GPUZ to keep an eye on your system and your GPU performance, clocks and temperatures.
