Regarding logging, I haven't fully built that out in Dell Fan Management but if you run it from the command line, you will get some text log entries dumped out there. Starting in 2021 (Tiger Lake systems) they removed the old interface that HWiNFO and other tools that can deal with Dell fans were using, so WMI is the only way to go now that I am aware of. I think any Dell system from 2018+ (maybe older), desktops included, supports the same WMI interface for reading the fan speeds. I did a lot of slinking around Dell's libsmbios C code (for Linux SMBIOS support), a lot of BIOS token/variable dumps, and some reverse-engineered Dell Power Manager code to figure this out. I am author of Dell Fan Management and I would be happy to pass along any information to help with this implementation. Instead of using a command-line to set the fan speed, an app would overwrite the text file, and FanControl would periodically read the file.Hi I just noticed this thread. One of the commenters suggested an alternative that would be easier to implement than command-line parameters: treat a text file like a temperature sensor.

(This is a hint to you to request it too.) I imagine it wouldn't take much time for the dev to implement it. Perhaps if enough people request it, the developer will implement it. However, you hinted that being able to reset the fan back to automatic (by command-line) is another one of your requirements, but you didn't literally say it is.Īt least two commenters have requested adding a command-line feature to FanControl. Assuming it understands your motherboard hardware, I think you could use it to set a constant fan speed of your choosing by constructing a constant control curve. FanControl doesn't accept command-line parameters, so it's not a perfect match for your request, but perhaps you can use it to solve your problem.
