How to lower fan speed on S17+ while in use?

So, I’ve got my S17+ running and when I access the control panel through the IP, it starts off fine for a minute, but then the fans kick into high gear and get super loud. Is there any way to quiet them down while I'm not actually hashing? Or can I just turn off the fans entirely?

Completely stopping fans from working will lead to an increase in temperature, which will shorten economical life-span. Do not try to stop the fans and always keep the temperature below <70°C. Adjusting the fan operation options and setting it to 80%-90% will reduce the noise somewhat. If the option is not present, try adjusting it manually as shown here https://bitcointalk.org/index.php?topic=5202112.0

nice screenshot Hes talking about stopping fans whilst the miner is offline and not hashing. Theoretically it shouldn't effect lifespan as the chips are not calculating.
