Need some help controlling fan speeds on a DELL motherboard. I know that this board can have software controlled fans, under Windows I can run SpeedFan successfully. 

 

I tried Dynamix Fan Control plugin, but it does not find / detect PWM controller - I'm not sure if there's a way to manually add drivers.

 

I also tried to follow this guide to manually create a script but running pwmconfig command returns:

There are no pwm-capable sensor modules installed.

 

sensors-detect command returns the following

# Chip drivers
modprobe coretemp
modprobe jc42

 

What else can I try? Any way to load up drivers for Dynamix Fan Control?

Either no one uses dell servers, or they are so clunky that no one has any answers.  I too am looking for a better solution!  With the dynamix plugin, i can control x2 out of all the fan headers, kind of (it shows x3, but one i don't have any control over).  The rest of the fans i have to set on high in bios, or they stay slow and let the system overheat during heavy workloads or if boot hangs!   its so frustrating/weird how little fan control we have in unRAID.  

I wish i knew coding, cuz i would just write my own scripts...if thats even possible.

Hi there, 

 

Same issue - different scenario - i recently did a case swap from an Optiplex 7 Series DELL Workstation moving into a Fractal Node 804. As DELL doesnt give a d**n on proper ATX Standards i got myself a swap kit to just be able connecting the Sensors and Front Panel Stuff properly.

Works pretty well but no chance since months to take control of that CPU fan - Bios says "adaptive CPU Fan Speed" (brilliant ;)) but fan goes up to max all the time. (Coolermaster Hyper 212)

Wondering if there is anyway to go to solve this issue and controlling it in unraid?

 

 

I'm just venting, cuz i woke up to my CPU around 100C this morning...the "Autofan" (only plugin that will even recognize 3 of the fan headers) was set to go full speed at 35C...but since all my drives were sleeping, it could care less what the PCI-e NVME drive temp is, and for some unknown and stupid reason, cant monitor the CPU/mobo temp and control the fan from that (like EVERY other mobo manufacture does).  and yes...the fans are set to max in the bios, but this Autofan program overrides that (which is fine to cut down the intense noise pollution...when it works).  

 

Yes...i hate my dell server.  I hate that i got it for a deal and cant afford a non-proprietary, wanna be apple trash, mobo!  I have a Supermicro at work that i have FULL control over and i love it!  But these Dell try to melt all the time, or i have to run the fans at full speed...all the time.  ***I would say a bunch of bad words here, but i don't wanna get banned***.  You know what you can do Dell...

 

I remember having a Dell Laptop that always wanted to melt and i couldn't get any fan program to work with it neither (windows); I did finally find some obscure university forum with some computer science major who made a script to control the laptop fans...it was clunky but worked enough to keep things from melting all the time.  Anyone know of a class action against Dell for this kinda nonsense?  🤢🤮🥵🤯🤬
