Octominer x12 fan issue!

Hi everyone. Im having an issue where when I plug my x12 up (before hitting power button) my fans go to 100 percent until hive os is fully booted and auto fan kicks on. Does anyone know how to stop this from happening? Im doing a lot of trouble shooting with cards right now so im rebooting a lot and the fans go full bore everytime its kinda annoying. Thanks in advance!!
