New PWM Fan installed, turns out PWM not available.

Hi there,

I'm running ubuntu server on my Wortmann Terra G2 with (now upgraded) 16G DDR3 Ram, Xeon E3 1220v3 4 Core, with now 6 Drives (2x8 TB HDD Raid1, 2x 1 TB HDD Raid 1, 2x 250 GB SSD - soon raid 1)

While I generaly know my way around ubuntu, the sensors lm is giving me a hard time. The G2 runs on an Asus P9D-i itx Motherboard with kvm module which I have not touched yet.

I bought a fancy noctua 120mm casefan since my harddrives run too hot in the case (which is tiny, google wortmann G2). The new fan runs well but I cant detect the fans for either the cpu or the case.

I tried sensors detect and installed fancontrol, just to find out the fans are somehow not discoverable.

Any ideas how to proceed? I'd really like to give the casefan a specific speed to run at. Pretty sure I could gain knowledge in the bios but i really dont want to bring a monitor to the server just for that.

TL;DR: my ASUS P9D-i board wont show me fanspeeds with sensors-detect. What to do next?

In any case, thanks for reading. Have a good one.

Edit: I put a picture of the tower in the post if you're curious. :)

Edit 2: I forgot I have the manual for the server mainboard on my pc. the mainboard can see the fanspeeds and you can change the behavior there. How would I change that?
