Question Is my pc thermal throttling? Or is something else going on?

For the last two months I have been experiencing performance issues in games, specifically fortnite. Before this started I never had this issue.

After playing for about 30-60 minutes my game starts to feel extremely slow and sluggish and my characters movement feels heavy and there is a bad input delay. When it first happened usually restarting my pc would fix the issue.
Now, sometimes it fixes it and other times it doesnt.

I have done a clean install of windows, updated and rolled back drivers. Re installed games on both ssd and hdd. I bumped up the fan speeds so that my GPU and CPU have been staying under 60c while playing, so i dont think its an overheating issue.

I saw somewhere that someone had the same issues and that even after upgrading parts, the only thing that fixed it was switching their pc case case apparently the ambient temps were high or something like that.

Could this be my issue or what should i be looking for at this point?

Specs:
CPU: ryzen 5 2600 (stock)
GPU: xfx radeon rx580
MOBO: b450 tomahawk
RAM: corsair 16gb(2x8 3000mhz)
MEM:500gb ssd / 1tb hdd
PSU: evga 600w br
CASE: nzxt h500i

cpu/gpu temp and usage during the game?
ram/sdd/hdd usage during the game?

Have you seen inside the cabinet if there is dust collected on fans ?

Yea i have, everything is clean, its like a 5-6 month old build so it is not dusty at all

I will do that right now and get back to you

cpu/gpu temp and usage during the game?
ram/sdd/hdd usage during the game?

So cpu and gpu temps are both between like 55-60.
Cpu usage is around 25% and gpu usage is around 50%
Memory usage is at around 40%
