Hi there guys, I have recently bought my first miner, its the S9 14Th version.

The only issue is, the intake fan keeps going into full power every so often and it's getting annoying. I am running a 5" duct from the exhaust fan to an open window (the aluminium ducting makes an 'S' shape almost and is around 3-4 foot in length.

How do I adjust the maximum fan rate or stop the fan from working overtime, it only kicks in every 20 seconds or so.

Thanks!
