So I recently got a new mobo (Gigabyte Auros B450I wifi pro), heatsink (Noctua NH-L12S), fans and case but I ran into a problem of my Noctua A12x15 PWM fan that came with the heatsink will not spin past POST. I did some tweaking to fix:
Reseat the connector
Reset BIOS
swapped fans
used UEFI fan controller and windows fan controllers to see to no avail.
I have 2 more A12x15 PWM fans so I swaped place with one of the case fans and the sys fans work but the CPU fan still would't spool past POST. THEN I connected a 3pin case fan just to see and that one worked perfectly. seems like theres a problem withe the CPU fan where the 4 pin fans aren't working. All the fan seem to work when connected to Sys fan but the CPU fan only works with a 3pin.
Any suggestions as to what, and how to fix the issue? I've already sent an email to the Gigabyte support to see if they can help as well.
