it wont hurt to turn it down a bit. but high gpu loads are k as long as your not dumping a load of heat into the case. big spikes on gpu loads aren’t that uncommon on load in.
if your think your pc is about to take off due to fan noise constantly then yeah maybe its hot.
are you taking about GPU 100 or gpu mem100%.
there should be loads of steamers talking about card performance and fan speed and setting for like normal operation.
But thermals on the cpu cores and heat dumped into a case and maybe on the dimms in overclock is what would worry me more. a gpu is usually smart enough to thermally throttle with drop in frames, a cpu will straight up shut down to save itself and give system instbility. some people use psus thaat are over 8 years old and they go bad with time. usually via a demanding gpu dumping alot heat in to the case (heat lowers the power supple efficency hence why they reccomond 15-20% over the total system TDP.
there various tdp calculators on the internet as well as pc part picker. the sudden surge on the psu on a older end of life psu will cause trip and shut the system down.
but that gpu doesnt sound bad,
