FPS drops predator helios 300

90-100C is not okay, I had that until 2 days ago, DO NOT listen to anyone who says that your laptop can handle it and that it is designed to withstand those temps. That is just stupid.
Ive heard that over 100 times.

I have to say this just in case, "Do it at your own risk",

I would advice you to reapply the thermal paste, I opened my laptop 2 days ago and I was hitting 95 degrees C almost every time Id play, the results were outstanding!!! *the temp decrease will differ from one laptop to another* but itll give you a huge boost! You can check my post for more details.

Let me tell you that this limits your CPU and GPU power if your PC/Laptop  overheats A LOT just so the temperatures wont go any higher. What that means is, once you hit 90 or 95C you CPU clock speed just goes down so itll use less power and the same applies to your GPU. So if your are going up and down in the 90-100 range your Performance is inconsistant because your laptop is trying to balance the power and the temps. Which causes FPS drops.

Update your GPU to the latest version and Your BIOS if you havent, a lot of times this causes the fps drop. It will not lower the temps but it might cause the fps drops to disappear, eventhough its more likely (1.) to solve your problem.

**Only if youve undervolted or overclocked**
If you have undervolted or overclocked your CPU or GPU, you might wanna change the value a bit . (if youve undervolted too much, increase the voltages a bit more and try playing games and see if you lag again and again until you get stable fps (try different games, to be sure its not from the game), note: Dont increase the voltages more than your default ones.
If you have Overclocked, lower them a bit and balance it until it stabilizes just like the previous one.

I hope it helped
