Relax, it is error in firmware. The motherboard thinks now that only three fans on the chassis for it are good. Two do not enought.
Connect to shassis connector(what need number - see log of error) another fun, and get green led.
Still an error. Motherbord operates speed of the fan NOT only on temperature, and by quantity of fans.
Connect small 80mm fan, and get slow twice big fan. It is stupid, but it is fact.
