I have been happily using spinpid.zsh to control the fans of my supermicro X10 board.
Now that I moved my nas to an Asrock Rack c3758d4i-4l, the script does not work anymore and I am not fluent enough in zsh to fix it.
Is there a similar script for Asrock Racck? Or something I can adapt? What do Asrock Rack gang use?
I could try to implement one but I have a feeling something is floating around (searching did not reveal anything)
I just set curves in the ipmi per fan plug.
I do not have fan settings in my IPMI for whatever reason 
Nothing like this in your IPMI for asrock? 
Which motherboard if you dun mind me asking?
Edit; I mean the options in there are a pain in the ass to setup, but does the needful:
Edit 2: obviously I re-read & see you running Asrock Rack c3758d4i-4l
It’s this board and I have no fan settings at all which is really strange. I will try a factory reset and see.
But if you set the fan speeds via IPMI, that means they are not tied to the actual drive temps. Or am I mistaken?
It does have some options, but nothing for the drive temps themselves. I have the fans for my drives set to a reasonable steady state, but your board does have a thermal sensor plug that you could slap onto your drives & have an actual curve set depending on the temps on the exterior of a drive
Plug #24:
Edit: seems I also have one on my board… will be ordering a probe & setting up fan curves for my HDDs too it seems…
That is quite interesting. Thank you.
I wish I could use that but I still have no fan control in ipmi after reflashing BMC.
Haven’t gone into the bios to set it manually, but it seems possible to manually set the fan speed curve per temp point - some bios even allow to set if it is the cpu temp, thermal sensor, chipset, etc. etc. that control the curve for said fan.
Just thought of something else; wht if you manually try going to the settings page for the fan?

Have you tried the Asrock Rack Server Management Utility (SMU)? The manual for this utility says it supports modifying the fan table.
Hi @MSameer would you be able to share the spinpid.zsh script?
If I can havea look and see if there is anything helpful I can point you toward. And it could help me in my endeavour to make my fans quieter…
I also don’t have a server grade mainboard, but i’m using coolercontrol deployed as a custom app to manage my fan speeds. All my fans are connected to the various fan headers and as long as they’re pwm fans i can adjust their speeds manually with a percent value or set fan curves.
The only issue i have is that i have to manually create an extra entry in modules-load.d to load an additional kernel module.
yes I can do that but I can also manipulate fan duty via ipmitool
It does not work. I reflashed BIOS, enabled inventory support because I read it might be a reason for IPMI not showing fan settings but it still does not show up.
It’s not working too. Not sure what’s with this board.
Sure, it’s the .zip.txt attached here:
Just rename it to .zip

I doubt it can be easily modified. supermicro allows setting a single fan duty cycle via ipmitool. Asrock rack needs all fans at once which means we need to read the values then set them all again. Agh 
But mine is a server grade motherboard with a BMC. it’s just that the supermicro script I’ve been using to set fan speed based on drives temperature is not working
fan.py.txt (2.4 KB)
I cooked a very basic script that will get the temperatures for HDDs and SSDs then set the fan duty cycle accordingly.
It’s very basic, no CPU temperature or fan control yet, not the best parsing and possibly buggy but it will work until I find out why fan settings are not shown.
Feel free to use/adapt/criticize/… etc.
fan.py.txt (3.2 KB)
This updated script will also take control of CPU fan. I set the fan duty cycle per a cpu temperature map since my atom CPU cooler does not contribute to cooling the drives.
I will use this script for now until I contact Asrock Rack and find a solution for the lack of fan settings.
