Hello, I am having a really weird problem and I need help fixing it. My CPU gets too hot and slows down often. When I run the GPU stress test, my CPU drops to 800MHz right away. But when I just stress-test the CPU alone, its speed only goes down a little bit. Here is what I have: Laptop is a Dell G5 5587 with an i7 8750h, a GTX 1060 Max-Q card, and 16GB of RAM. For the GPU test, I used FurMark. For the CPU stress test, I ran Prime95. Could you please tell me what's going on? I am totally confused about this situation. EDIT: I attached some HWiNFO graphs that show more details here.

If you're running a GPU test, your CPU only has to do a little bit of work.

Sure, but if your game is playing okay at first, then suddenly drops down to single digits on frames per second for a few moments before coming back up to normal, that's when things get weird. At that exact moment, the CPU has slowed itself down to 800 MHz because it thinks the load is too heavy.

Do you want to plug in your power while gaming? It might make it feel slow, like throttling. Check out this link for a tool called ThrottleStop.
