K8V SE Deluxe + Antec Case = no power fan speed and no front 1394?

Hi All,

I have a 1 month old K8V SE Deluxe and Antec SX1040-II case. This
combination works really well and the extra cooling fans are a nice bonus.

However I have 2 problems which I'd like a little feedback on before I raise
it with the vendor:

1. The PSU has a sense wire for the motherboard so I can detect/monitor the
PSU fan speed. This doesn't work. In fact, no fan I plug into the
motherboard's "Power Fan" connector detects the speed. Yes, I'm using fans
with the sense wire that I know work - I can get a fan speed using the
"Case Fan" connector on the same motherboard. Have I missed some funky
BIOS feature or do other people have problems with this too?

2. The front FireWire connector doesn't work at all. Nothing I plug it into
the front FireWire port is detected. The USB2 connectors work, and yes,
I've tested the FireWire devices on the hard-wired connector on the back -
success :) Seems the wiring for the front FireWire port on my Antec case
might be wrong. The K8V came with an extra bracket+lead for a 2nd rear
FireWire port - this one works fine. Just the case FireWire is screwy.

Any ideas folks? Looks like the mobo power fan sense is fubar, but I might
be able to re-wire the case's FireWire connector. I'd really prefer to
keep the case, it took me ages to wire everything up nice and neat. The
mobo OTOH I can swap in-and-out relatively easily.

Cheers,

James

The nice picture in your Asus manual, shows the board uses the
Winbond-usa.com W83697HF. The datasheet is here:

http://winbond-usa.com/products/winbond_products/view.phtml?name=PCIC
http://winbond-usa.com/products/winbond_products/pdfs/PCIC/w83697hf.pdf

On page 100 of the document, you can see there are only two
fan speed sensor connections. That would explain why the third
connector has nothing connected to the speed pin.

As for the Firewire, I have several Antec cases, and on one of them,
the Firewire data pins are reversed. Something like TPA+ and TPA-
are swapped with each other. TPB+ and TPB- are swapped with each
other. This is not fatal, and shouldn't burn anything, but I doubt
Firewire was designed with inversion detection for problems like
this. (Watch out if VP/VG are miswired! Expensive Firewire
toys could die.) Antec has had the odd web page, explaining
their mistakes, but they redesign their web site enough, that
links to these pages are dead.

Since case manufacturers in general have a bad record with respect
to miswiring the case front panel, I recommend using an ohmmeter
and readily available pinout info on the Internet, to buzz out
and verify exactly what wiring is in the case. I'm so sick of
miswired cases, that when I got my Antec Sonata, I simply ripped
out the module that came with the case, meaning three less cables
dangling around loose inside :-) Since my computers live on top of
my computer desk, the connectors on the back are readily accessible
when I need them. My desk is huge - I built it myself :-)

Many case manufacturers continue to ship cases with USB 1.1 only
wiring on the front panel. Even though we are firmly in a USB 2.0
age, they insist on shipping crappy wiring. Caveat emptor.

HTH,
Paul

I plugged a fan into the power fan connector on my K8V-SE DLX
MB and it didn't show the speed either. I looked thru the BIOS and it
doesn't have any settings for the power fan. The other two you can
set to ignore. Also the manual doesn't show any settings for it either.

Both fire wire ports work on my MB.

I love my antec case (tho it's not the same as the one you have)..
mine had some serious problems (that antec didnt want to talk about)..
The notch for relasing my front panel wasnt added on the units side door..
so when the door was on the front panel couldnt be removed (in fact, it put
the front panel in such a bind that I am lucky it didnt break).. so I had to
cut my case..
My (I think) usb cables were incorrectly labled too.. They simply sent me an
email saying "here is the lables you have on your wires" and I said no and
told them what I had and they told me I was wrong lol..

I KNOW that many of their old front pcb's for the usb stuff had to be
replaced because it didnt work with usb2.0 but I havent ever heard of any
firewire problems (is the stuff working from the asus firewire connector?)..
You might have to check their connections against the antec one to figgure
out the correct sequence..
 
Not sure about the fan Connector...I have the same board and all three work
fine (One CPU fan, One Pwr Fan and one Chassis Fan). If you have Cool 'n
Quiet enabled, not all fans will run at all times. When the Mobo/case heat
reaches the predetermined limit for each fan, then the fans will turn.

On the P160, the front Firewire pins are labeled wrong...here is the answer
as posted on the ANTEC website:

*What is the correct color code for the firewire connection from the front
panel?*
The color code for the firewire connection is as follows:
VP = white
VG = black/white and black
TPA- = blue
TPA+ = yellow
TPB- = green
TPB+ = yellow/black

Use this as your guide and your front Firewire should work.

Thanks for that. I did the re-wire (all the TP?+/- were opposite to the
mobo header) but still no joy. I think I'll just rewire a whole new lead
straight from the front so it matches the Asus lead. No biggie, I'm
comfortable with soldering irons and wire cutters :)

Let me know how it goes...would like to know what the correct pin out is
myself.

If you are handy with a soldering iron, you are also handy with
an ohmmeter. Just grab a wire, and then use the ohmmeter to sense
which Firewire connector pin it is joined to. I figured out the
miswiring this way on my own, without ever connecting a Firewire
device to it. It was only later that I found out that Antec had
a web page admitting the mistake.

Page 37 of this document, has the nicest picture of the Firewire
pinout. The rest of the pinouts on the web, don't indicate which
view of the connector you are looking at. This one is much
clearer. (Page 34 has the USB pinout.)

Thanks for the catch on this one....I have printed the two pages and it
now has a permanent place in my reference folder...

Thanks for the link - makes life easier :) As for the multi-meter
suggestion, that is the first thing I plan on doing (except using
continuity instead of impedance). However, the Asus port has 10 wires into
9 pins (2 earth's are connected to same pin), but the Antec lead only has 6
wires. I need to map out what "wires" are missing from the Antec lead and
whether or not they are significant - my gut is telling me the extra wires
on the Asus header are simply earth wires, but I haven't checked closely
either.

The extra grounds on the Asus pinout are for crosstalk reduction.
The grounds separate the "A" diff pair from the "B" diff pair.
If twisted pair wires are used and there is some physical separation
between the wires, then using isolation grounds isn't as important.
So, whether the grounds count, depends on what kind of cabling
is used to carry the signals. (Isolation grounds are why the 80 wire
IDE cable exists - 40 of the wires are ground and those ground
signals isolate the data signals from one another.)

Can you test your Firewire peripheral some how, to see whether
the interface is still alive on it ? I sure hope the power
didn't get reversed or something. Since most Firewire devices
are expensive, the thought of "case wiring roulette" would make
me want to avoid the issue entirely. That is why I removed my
front panel assembly from my Antec Sonata - now there is no
temptation to use it :-)

Good luck,
Paul

Yep - understand that :) Did a Ba. Eng. (Comp. Eng.) before switching to
Computer Science. ;)

The data wires were reversed but not the power. My digital video camera is
still alive and I can read/control it from the hard-wired 1394 port on the
motherboard just fine.

Heheh - yeh, I'm becoming a little cautious about all this after reading the
spec on 1394. It would be easy to nuke the device by routing the power to
TP?+. That would hurt, not just my expensive digital camera, but also my
wallet!

Thanks for all your help Paul. I'll try to remember to port back the
results once I get around to the rewiring :)
