speedfan won't detect speed of case fan

Uptime73 · Aug 7, 2008

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!

it might then no guarantees tho. Open it up and look at some of the AUX fans, it may be there!

well if the bio's can't see it speedfan can't see it.

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

I think BIOS show speed of cpu fan only

That means your board only has one fan sensor.

mh my board has a lot of fan speed sensors, and the fans are plugged into the mobo, but i cant monitor nor see fan speeds... why?
p.s. sorry i am stealing your thread, i have the same problem as you

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.

i did: no way

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.

yeah sure i know that, everything is 3 wired. but it seems i'm stealing this thread. Sorry!
