    I emailed MSI with the following problem on my new (less than a week
    old) K8N Neo4-F.

    The fan for the North Bridge Chip runs, but doesn't show as running in
    the Bios. I've flashed to the latest BIOS
    version (1.B) and still nothing. Is my board defective?

    MSI response:
    This indicates either the Fan sensor has problem or the fan header on
    the mb has problem so please kindly confirm by connecting a known
    working fan on the NB Fan header to test first.

    My response:
    Thank you for responding. I've tested another working fan and still
    get no reading. I can see that the fan is physically running.

    MSI response:
    Then this indicates the fan sensor on the fan header has problem.

    My response:
    What should be done to correct this issue? Will this effect the board

    MSI response:
    It will not effect any system performance, just the sensor is

    My response:
    If the fan stops spinning, and the sensor doesn't notify me, won't
    the Northbridge chip overheat and fry the motherboard?

    MSI response:
    Yes, it will which you can have it serviced:

    What the ____, I don't understand why they wouldn't want to be
    proactive with this problem instead of reactive. There is a problem so
    why not fix it or replace the board?

    Help, I need to know what you would do? Would you risk it and leave it
    alone for now and wait until it had a problem, and hope it's still
    covered under warranty. Or would you expect and demand a replacement
    board now.

    It's far more cost effective to fix a problem if and when it happens.
    Obviously this is no good for you cause there
    is the possibility that you would get stuck without a PC unplanned for a
    while. It's just the way the businesses run their operations.

    did you consider emailing or phoning the place were you purchased the
    motherboard and explain it to them?..Now I know Asus has an Advanced RMA
    service (they just don't tell ya)but am not sure if MSI has the same in
    place. By advance RMA'n you would only be down the time it took you to
    change the have the charge of a 2ND motherboard on a
    credit card till it is returned.Just as a point of interest...where did you
    buy the motherboard from?

    also..just for general info...I have 2 NB fans being shipped to me from
    MSI -Canada for defective ones...I did not have to send the bad ones in
    first.they are for Neo4's..those fans have a tendancy to dry out quickly and
    they can also emit a high pitch whine which is hard to track..except for the
    headache it can cause.

    I leave my computer on 24/7. When I came home tonight I couldn't
    believe the high pitch sound coming from it. Not impressive if you ask
    me. MSI knows there's a problem, so why don't they do somthing about

    so is it the fan squealing?...I would contact Newegg and see if you could
    get an "Advaced RMA"..I did that with TigerDirect for my MSI K8N
    Neo2-F..that way you will only suffer the swapout as downtime.

    Different strokes for different folks.

    Fan sensors are su·per·flu·ous !

    I wouldn't experience one second of down time because a sensor wasn't
    working. Never in a million years would I even consider the thought
    of taking the trouble to send in a board because of a defective fan

    funny thing about those northbridge fans

    Well, firstly I had no idea my northbridge had a fan on it but here is the funny thing....The fan wasn't working and hadn't been working in some time! I suspect the fan must have got a dust clog and jamed and burned out.

    Ok I have a ms-7125 and an AMD 64|3000 and one intake and two outtake fans pluse the usual CPU heatsinK fan and a fan that is above the northbridge in my graphics card. The temps I have currently are CPU 91F and SYS as 95F.

    Note my computer isn't crashing or even malfunctioning or showing any sign of a problem. I have no idea when the fan burnt out and until I started running core center I had no idea it wasn't working as I had no reason to open the silly thing.

    It is possible that with enough ventilation the chip will not overheat, fan or no fan.

    That being said I would like to replace said fan and would love to know WHAT kind of fan it actually is besides being as thin as a cookie and hiding under my AGP card.

    Thats a bad design MSI. Yoohoo!!!!!

    So what kind of fan is it and what do I need to replace it with? I note it is partially a heatsync too and not just a fan which is probably why my mobo is still around and not deadsky
