It is probably overkill but it's stable. It doesn't even get that hot, because it's an oddball 65w version of the 5900, and because I put a ridiculous overkill tower cooler on it, then strapped a 140mm fan onto one side fur push-pull airflow and bolted all the fans into the case that would fit. I occasionally think about cutting and drilling additional fan mounting points just on general principles, but I can't say it's ever had a heat problem as it is.
Rendering? I sometimes think about learning Blender, but no, the closest thing to that is using Stable Diffusion fur waifu images.
