For example, mess with mlxi2c_bf to tweak fan speed parameters.

Code:
mlxi2c_bf --master-mode set_fan /FAN/FAN 1 65
mlxi2c_bf --master-mode set_fan /PS1/FAN 1 65
Do you know how much quieter it typically is when you tweak fan speed parameters? And how much hotter it typically runs with the reduced fan speed?

Thanks!

The SX6036 was a little bit quieter and the SX6018 could run the fans quite a bit slower and was a lot quieter. I'm unsure if my SX6036 being single PSU and the SX6018 being dual PSU had any difference on how slow I could run the fans before tripping the fan alarm which ramps everything to full speed.

In both cases the main CPU temperature went up I think around 6-7C to a bit under 70C. I don't have either of the switches online at the moment to check.
