K8N-E Question about Powerfan Threshold

Using PC Probe tells me that the Powerfan is below threshold. Obviously
because there is nothing connected to it.

All fans seem to be spinning. Just confirming that I should just uncheck
this setting for monitoring?

Also, what is the connector for? Just an extra fan?

I actually thought it was getting that reading because I might have
negelected to to put the cable coming from the power supply to the PWR_FAN
connector. (currently on the chassis connector and works fine. I get a CPU
error when it's connected to the power fan connector)

Many thanks in advance.

If there is no fan connected to the fan header then there is nothing to
monitor so uncheck monitoring in pc probe.

yep, most asus boards have at least 3 fan headers with monitoring,
usually named CPU, Chassis and Power.

That's weird. My PSU has a wire for the fan also, but it's only for
monitoring the PSU fan speed, not powering it.
Many thanks in advance.

Thanks for the reply.

Got another question.

Receiving an error sometimes when booting "CPU Fan Error, Press F1 to
Continue". All fans are confirmed working.

CPU temperature when booting to BIOS upon boot is about 42C/107F and
climbing rapidly.

When booting into Windows, temperature reduces to about a steady 38C/100F.

Cool n' quiet is disabled.

Thanks in advance for any help.

Make sure the CPU fan is plugged into the CPU fan header.

Try another known working fan on the CPU fan header and see if you get
the same error,(in the meantime plug the CPU fan into another header
(like Power) or IDE off the PSU with a 4 to 3 pin convertor.

Temps vary, your room temp, case cooling, HS/fan type all make a
difference so it's hard to say, all I can say is if you installed the HS
fan correctly it should be fine.

Sounds about right, depending on room temp (and not overclocking) my
2.2ghz newcastle idles in the low to mid 30s with stock fan w/CnQ
disabled.
Cool n' quiet is disabled.

Do you have Q-Fan enabled? This will throttle fan speeds according to
CPU temperature in order to quiet down the system. (It operates
independently from Cool'n'Quiet.) In my experience, it doesn't work
well, so I just turned it off.

This particular problem seems to be caused by the fact that when the
system is powered up cold, the CPU hasn't warmed up enough to require
the fan to come on when the POST checks CPU fan speed. So it complains
about a fan failure.
 
I'm not positive which one I have enabled right now (Q-Fan or Cool n'
Quiet), but playing with enabling/disabling each, tells me that either both
have to be turned off or only one can be on (I think it's Cool n' Quiet. I
think the Q-Fan stopped the CPU fan).

Turns my 2nd problem with the CPU fan not spinning upon bootup was a BIOS
problem. I had updated to the lastest bios 1006 and for whatever reason the
CPU fan would not spin. I installed the first BIOS version, then upgraded to
1005 and it seems to work well. Temperature seems quite cool now.

Thanks for everyone's help.
