Hi - thanks in davance for all help - I searched the other posts but
cant find reference to my MoBo :

On boot I get 'CPU FAN FAILED' from POST - this stops the boot awaiting
[F1] to continue.

I have a mCubed T-Balancer managing all my temps and fans - I dont feed
back the fan connectors to the MoBo headers purely because of the
amount of wires involved. (another TBAL post alongside this one - it
puts everything to [maximum] periodically /shrug)

** It seems that the POST messages can be disabled in BIOS - but I just
can't find it for my PC-DL Deluxe. **

While I'm in there I'd like to disable the 'NO KEYBAORD DETECTED' as
well - my Logitech LX700 cordless desktop is all-USB via the receiver -
so that is also not detected properly - but this doesn't stop the
boot-up.

Thanks again, regards

You have an option on the main BIOS page called "Halt On",
near the bottom of the screen. By default, it is [All Errors]
and setting it to [No Errors] is the most extreme fix.

Section 4.5.1 in the manual, for the Hardware Monitor, doesn't
suggest the standard user interface. Usually you can cursor
over the fan field, and toggle the monitoring for a fan to
[Disabled] or the like, to stop fan monitoring complaints.
But, perhaps in this case, the "Halt On" setting is the
only way to fix it ? Maybe the actual BIOS has the fields in
the Hardware Monitor as user definable ?

There certainly isn't the standard BIOS/Hardware menus that seem common
on most recent ASUS MoBo from the other posts I read.

I'm scared of the [dont halt regardless of an error] approach - and I
thank you for pointing me to it.

Anyone else have a cunning plan .?

I should add that - although I pointed out in OT that I dont feed back
the fan speeds to the MoBo - I have tried this but the speeds are also
too slow for it to detect and I'd rather not take this approach

Regards and thanks Paul.

What if you find the fastest fan in the box, and run a cable from
that channel of the T-Balancer to the CPU fan header ? Would that
fix it ?

Then you could "Halt On" [all, but keyboard] to ignore the
keyboard errors.

Other options include, sticking a separate three wire fan in
the box, for the sole purpose of generaing a tacho signal
to feed to the CPU fan header(s). If you are good with a
soldering iron, it is possible to feed just the tacho signal
from one fan, to multiple fan headers. AFAIK, it is an open
collector interface, suitable for wired-OR.

Hi - I did have the fans back to the MoBo from the TBal - some obvious
problems are that this is a dual Xeon CPU MoBo - so u need 2 - even
then they weren't fast enough - I'm hoping there is a firmware/hidden
setting/non-standard application that will disable the BIOS.

I *think* the TBal starts up on max to negate this problem - then backs
all the fans to the pre-set levels - the whole setup takes some booting
(RAID SATA disks etc) - I originally thought it was taking too long and
the TBal had not kept the fast setting long enough - this was when I
had it wired back to the MoBo.

Thinking about it - the CPU FAN FAIL is very early on in the boot
sequence.

I'll hope there is a setting someone knows - thanks again for the
follow-up

Regards
