Is there a way to get Asus Probe to show the PWR_FAN header reading so that
I can see the RPM's for my PSU?
I have an A8N_SLI Deluxe and Enermax 535w PSU.
Thanks

The picture in section 4.5.4 of the manual shows CPU, CHA1, and
CHIP (chipset fan) are monitored. That means PWR_FAN is just a
source of +12V for a fan.

To prove the interface on the PSU works, try connecting the
PSU to the CHA1 header. That will at least tell you there is
a working RPM signal on the cable.

As for your monitor chip, it has up to five fan speed channels.
But the tachometer input signals for channels 4 and 5, use the
same pins as the GAME connector (joystick interface). Since
your motherboard does have a GAME header, that means only three
fan monitor channels are available for fans. And since the BIOS
lists three channels (CPU, CHA1, CHIP), it means there are
no "hidden" fan speed channels in reserve, waiting to be
unleashed.

Wow, thanks alot.
Hm, oh, I thought pwr_fan connector is where the psu fan monitor is supposed
to be plugged, hence the label.
The problem with CHA1 is that it's located WAY down at the bottom of the
board.
The fan monitor cable of the PSU won't reach that far.
Great info though, and it makes sense.

Maybe they shouldn't have bothered putting the PWR_FAN
header on the board. It seems kinda strange, but this is
not the first board where that stuff doesn't line up
properly. There was one board, where you had to plug the
CPU fan, into a header other than CPU_FAN, so these
things happen.

There is no way to get Probe, nVidia Monitor, or MBM 5 to read that
header. As Paul pointed out, Asus probably had to cannibalize a
connection to it for the game port or some other mobo device (Paul
will correct me if I'm misquoting him).
I suppose it'll supply power to a case fan, but I've never tested that
guess. No one can understand why Asus doesn't change its misleading
label.

So sorry to have posted this redundant stuff. I apologize for jumping
in before realizing that the question had already been answered. :-(
