I have a Asrock pro3 gen3 motherboard and an i3 2120. My CPU and two chasis fans are running all the time. I have the CPU and one chasis set to auto and the second chasis set to full. My CPU is idle and temp is 32°c and the target temp is set to 50°c and CPU fan is still running. Shouldn't it be off at these temps? I have a similar set up for the chasis fan and it always runs as well. Really annoying to have all fans running all the time. Thanks guys.
