The fan sensor isn't working but the fan may still be spinning on its own power.  It's definitely not spinning at 18k or 30k RPM because if it was, it would destroy itself.  If the temps are okay, you are getting good airflow, and the miner isn't shutting off due to high temps or a no fan signal you will be fine.

This happened to two of my gears but only after i replaced a fan on each, unfortunately for me the miner did not work and it was stuck at "checking fans" phase, it was also showing 30k RPM.

For one miner I replaced the other fan with the another new fan ( the same type that shows 30k) and both started to show 6k RPM and worked fine, for the other gear I had to use another fan, but as the comment above mentioned, if temps are good and miner isn't drifting ( mine was drifting for real) then i wouldn't worry about it.

thanks alot hockeybum.
