I have a pretty new S9. The fan speed keeps reving up and down every 20-30 seconds. The boards hit 72`C which is where the fans go into crazy mode and lower it back down to 68, and then slow down. Few seconds later, it's back at 72, and this happens again.

Anyone have a solution?

The s9 is doing that to keep the chips in a safe operating temperature range. It is working as intended. There is no solution because there is no problem.
Stop buying industrial miners, running them at home, and then complaining about the noise.

OK thank you. Just thought it would make more sense for the fans to run consistently rather than reving up and down.
