Hi i have a big problem with the motherboard. I recently built in a new case with my old components of my HP Omen 880-138NO (https://support.hp.com/id-en/document/c06057343). The problem is that everytime i boot up i get the error message "System Fan and Cpu Fan 90B are not working correctly, shutting down in 15 seconds". Ive tried to update the BIOS, cleaned around the cpu fan, done a hard reset. But none have worked. When i connect the cpu fan to the motherboard it goes crazy and spins around 4500rpm. Ive tried to change the cpu fan, still the problem persists. All my other fans are connected through my powersupply since i have a Cooler Master Storm Trooper case.
