September 20, 20232 yr Hello all, I am running 6.12.4 on my Lenovo ThinkStation P620. However, there seems to be no way to control the fans, as the motherboard fan controller is not detected by UnRaid or the Dynamix Fan Control plugin. That means the only way to control the fans is to set them in the BIOS, and they sound like a goddam hurricane when they are turned up, which I do not like. It is in my basement, but the noise is just annoying. So, I was thinking of disabling the motherboard fan controller and adding a third party controller that can set the fans dependent on system temperature, etc. I don't mind the fans running when needed, but I don't want the noise when the system is idle. Are there any third party fan controllers that are detected and compatible with Dynamic Fan control? Considering something like this: https://www.corsair.com/us/en/p/custom-liquid-cooling/cl-9011110-ww/icue-commander-pro-smart-rgb-lighting-and-fan-speed-controller-cl-9011110-ww, but without the blinky lights.
September 21, 20232 yr No need for that. Go into your bios, then Power on the left and then on the right, towards the bottom, you can control the stepping of the fans. Ref - https://download.lenovo.com/bsco/index.html#/graphicalsimulator/ThinkStation P620 (30E0,30E1)

The only way to get decent ventilation to the hard drives is to run the fans at maxiumum, which is damn noisy. I really want more nuanced control that allows me to vary fan speed based on temperature, or to run the individual fans at different speeds.
December 23, 20232 yr Did you find a solution for this challenge? I'm in the similar situation with P330.
July 17, 2025Jul 17 This is a hassle for me as well. I want to attach a 220V, 9cm fan in front of my chassis, controlled by a smart plug. The smart plug will be managed by Home Assistant and the Unraid plugin. This is a workaround for situations where dynamic control of the fan isn’t possible. If your NAS is located in a storage room, it might be easier to just set a fixed fan speed in the BIOS instead of going through all this effort.
