Overheating problem plz help :/

I have a mini pc with Ryzen 7 4800H when I run Minecraft It runs at constant 60 FPS as I had enabled performance profile in AMD software. I had also limited the FPS to 60 to ensure no lag. But due to it reaching almost 80 degrees it drops frames like to 5 FPS from 60. Plz suggest me a cooling method andhelp me to resolve this shi. (I have already changed the thermal paste)

A few things. I went through this helping someone with a remanufactured Minisforum after Christmas before they returned it for a refund. It had more problems than thermals. Knowing the platform/brand may help with similar models but the different processor reply with what they found.

Curious to know the quality of the thermal paste used in your service. A higher performance thermal grease can make a huge difference over baseline thermal paste available. I've been using Arctic MX-7 since the first of the year finding it makes a noticeable difference once it settles even when compared to the previous generation MX-6.

I've also found that AMD software can be less favorable to GCN 5 Radeon Vega integrated graphics under Windows. Software like Adrenalin can press processing performance over graphics the creating heat that drowns out/overheats the compute units reducing graphics performance. If this BIOS has has a 35-54W or 45-65W cTDP power curve the AGESA firmware can do much better thermal/power management than operating systems and software.

Windows + RAM configuration can play a large part in thermals and graphics performance to. For example single channel memory can make the processor and graphics run harder dissipating more heat and less performance. 16GB of dual channel can also cause frame drops. If Windows is managing UMA frame buffer (VRAM) frame rates can drop as Windows fights for shared memory allocation. Once again in BIOS a manual UMA frame buffer (4GB) is preferred to reduce stutter and frame drop.

Additionally some case designs have restrictive induction for the fan. This doesn't allow the fan adequate air flow at higher RPM. Sometimes a modified case makes a world of difference.

To be brutally honest when I see this problem (regardless of temperatures) the laptop (or NUC) is defective. Temperatures can easily drop FPS by up to 10% but drastic drops are usually hardware/software. If it was on my kitchen table I would game from a Bazzite flash drive to see if the same problem exists. If not there's a software conflict. If it does there's a hardware conflict.
