MacBook Pro 2017 insanely slow and fans always running

Bought this MacBook for very little and now trying to put a new os in it after resetting it and Ventura recovery was basically unusable so I tried even putting HIGH SIERRA on this USB and this Mac takes insanely long time to load it and when it loads it acts like everything is slow mo Even my core 2 duo models are miles faster Pram reset didn’t help What is broken here and how to fix it ?
