Undervolt your laptop (read up properly on how to do it)

Compressed Air + Air Vents

Laptop Cooling Stand

Reapply Thermal Paste (hard to do)

Thanks! Undervolting it helped, improved a decent amount. The others seem hard - could it also be the heatsink?

Using a compressed air can is super simple, if you have a few bucks to spare. Go to any computer shop, get a can of compressed air, and blow into your air vents/fans (make sure laptop is turned off, battery is taken out).

Although some of the dust may go in deeper, most of the built-up dust will come out hopefully. Maybe search online to see if anyone has attempted it with your laptop model. My laptop temps went down by 15-20 degrees after doing this.
