Hello all. I just installed an Antec case fan and when I brought up speedfan, it doesn't detect the speed of the case fan, although BIOS doesn't either. If BIOS doesn't detect speed of case fan, will speedfan still be able to detect it? Thanks.

Case fans will not be monitored by any software if it isnt plugged into the motherboard!

Speedfan looks at bios for the sensor addresses. So if the bios doesn't show the rpm, so wont speedfan.

Do you read your mbo manual you will find right cooling fan connector. If you don't put in right connector bios or speedfan can't read it.

Is your fan connected with 3 cables ? The third (i think yellow) cable is the RPM monitoring, however many fans come only with 2 cables (red and black) and those cant be monitored.
