as hwinfo object (program) does not detect the fan speed of the CPU; I already tried other fans but with the same result; from bios speed it is still readable. detaching the fan, by attacking an 'other always the same attack on the motherboard, and hung up the first fan, reading seems visible again; but being a ploy unacceptable and unlikely to do this, ask for clarification about.

My mobo is an 990fx extreme 9 and cpu is a fx 8320e

There is no standard when it comes to motherboard sensors, the configuration can vary from manufacturer to manufacturer and often from one model to the next. HWinfo and other 3rd party apps do their best to guess and usually get it right but not always. This is not a fault with your board, it is the monitoring app likely not assigning the correct sensor data for your CPU fan. Now if it is not reading correctly in BIOS that is another matter. You check for updates to the monitoring app you are using or try a different one.

i've yet try other program with same results. then i guess my fan peed control not work properly becouse the fans speed start spinning at max from another temperature and not from target temperature set in bios.

and the cpu fan speed is read in bios as NA and after 4 sec is read to effective rpm. while the other fan (chassis one) is read correctly from 0 sec in bios

in bios hardware monitor, che cpu1 fan speed is reading to n/a. after a while, the reading is correct, why?

hwinfo not reading cpu fan speed, but if I install axtu (asrock extreme utility tuner), cpu fan speed pop up in hwinfo to 0 rpm. In bios the rpm is reading. Only with cpu fan1 the issue occours. Cpu fan 2 and the other chassis fan are reading in hwinfo. Please help me. Thancks
