However, that still doesnt solve the issue (i guess software issue/limitation) of the case and cpu fans not be picked up or recognized by HexOS/TrueNAS despite BIOS configuration and MB connections If its a limitation, so be it. But I just want to make sure im not just missing something stupid

Nevermind, I finally just gave in to go have a look. There are BIOS/hardware settings for both the CPU Fan and the case fan, though those are a pain to get to. For full circleness, I consulted this reddit post for actually tuning the fans/understanding whatever the hell UGreen decided to do for their fan modulation Specifically this section: (From user u/mwlx86)

Hello, As the title suggests, running HexOS on a UGreen DXP4800 Plus. For the most part, temperature in case is fine, hard drives never get above 40 C. However, under load (especially significant load), the CPU spikes to ~80-90 C and acts like the 2 fan coolers in the case arent doing anything (i.e. the pitiful one on the heat sink and the 140mm case-mounted fan pulling air across the case) I've tried several things to try and even see if I could get control of the case fan through IPMI, but had no luck. Tried a docker app (not exclusively in TrueNAS, ran it locally by command line) called CoolerControl. Supposedly, its supposed to pick up all sensors and hardware (like fans) related to cooling. It picks up my CPU sensors and my hard drives sensors, but cant seem to see either motherboard 4-pin fan Is there something I can adjust in initial boot, either on MB BIOS or HexOS first start? I haven't tried those "physical" methods just due to the pain of physical monitor/keyboard connections from where its currently situated, so i just want to exhaust all non-physical methods before trying to do it by BIOS/Boot menu Any other ideas, im open to Thanks to advance
