If you make sure the fan is always running fine, the 80A is fine. If the fan fails for whatever reason, it WILL get hot and thermal. The 150A model will heat up less with the same current (more FETs with lower resistance), so not as important to keep the fan running. However, I haven't used the 150A yet, so I can't guarantee that...
