Antminer S9 - Exhaust Fan Will Not Exceed 600 RPM

I have one S9 with a fan that will not go faster than 600 RPM. The miner stops hashing just a few minutes after boot up, I am guessing due to high temperatures as they climb quick up to 99 before the hashing stops. Kernal Log does show a Fatal Error for Hight temperatures.\

Ive replaced the fan with a working one off my other miner, updated the firmware and dusted out the miner hashboards (did not remove them) and still having this issue, What is controlling my fan and keeping it at such a low RPM? Any help is greatly appreciated.
