Psu Fan Speed Sensor


Recommended Posts

Since installing my new Enermax PSU yesterday i relalised that the PSU comes equipped with a 3-pin adapter that plugs onto my motherboard to detect PSU fan speed.

My motherboard (MSI KT3 Ultra) does support this feature as i have consulted the manual.

However my motherboad software (MSI PC alert 4) reports a PSU fan speed of 0.

I know the fans on the PSU are spinning, so i'm not sure what the problem is.

If i plug a standard case fan in, again it does spin, but it dectects 0 rpm.

Any ideas?!

How fast is the fan spinning? is it on full speed? I find with my Enermax twin fan PSU that if the adjuster is wound up to full speed it wont register an RPM, howeaver if I turn it down I can get an RPM reading, give that a go and let us know how you get on ;)

Tried that, its a no go.

Also in the BIOS it does not show up at all under the PC Health Status along with the other Sensor readings.

Maybe i have a duff board :(

.

Is it supposed to show, does it say so in the M\B manual.

Is there any unusual or mysterious jumper settings? :unsure:

There's this from msi, that states support for low rpm fan, but does not state which fan.
