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.

Motherboard: Tampa2 from HP

First question, why did you rebuild the prebuilt into an aftermarket chassis?
Second question, are the fan headers on your motherboard bare?
Third question, what fans were on the prebuilt prior?

Answer to first question: Good question. I did it because the temperatures were very high on the last one and for future upgrades (example fitting a radeon 6700x with a good amount of airflow) The buttons on the front panel also got stuck sometimes. Also the new PSU i got didnt fit the case. Update: My motherboard is now dead for some reason...
