Asus probe not reporting PSU fan RPM.

[Andy Lawson]

Hi all,

I recently replaced my PSU, and the new unit has a PSU fan RPM
connector, so I connected it to my A7V600. The BIOS reports the fan
speed fine, but Probe 2.22.04 running under Win2k SP4 reports it as zero.

Any ideas?

Cheers!

On Monitor summary page check/tick the power fan box

Oops - forgot to mention - I already did that. It's at that point that
it starts alarming.

Up(or down) the Threshold and see what happens.
Some fans run at to low a speed.
My PSU fan can drop to low rpms and trigger the alarm.

It reads as zero - I'd have to drop the threshold to nothing.
It's not the alarm threshold that's the problem - it's the fact it does
not read the fan RPM. For some reason, Probe can't read the info even
tho the BIOS does.

Cheers!

Got the same problem. Bios read PSU Fan speed correctly (~1900rpm) but Pc
Probe shows 0 :/

Tried a lot of pc probe versions but no solve at all :/

Sorry for the email, I meant to reply to group

You have to change the fan divisor. The default fan devisor may be set too
low to read a low rpm fan. The default fan divisor is 2. Try setting it to
4
or 8. I'm not sure if Asus Probe allows you to change the divisor.

I use speedfan so I was able to change it in the advanced settings. Asus
Probe and Speedfan don't seem to work well together so I only run Speedfan
now.

When I upgraded to an Antec power supply I was getting 0 rpm in Speedfan
until I changed
the fan divisor.

Maybe somebody here knows how to adjust this setting in Asus Probe. I
assume it's a registry entry -?-
