Fan Speed Question

Hello,

I have a Biostar M7NCD motherboard. I am using Winbond Hardware Doctor
to work with the Winbond hardware monitor chip on my motherboard.
Everything seems to be okay except for a warning that my Sysfan speed
is under the limit. It says the CPU fan is spinning at 4693 RPM. My
CPU temperature is at 46 degrees celsius, low limit is 75 degrees and
the high is 80 degrees. Is this something to worry about? Can the fan
speed be adjusted in the bios or is a new fan the option? Or is this
nothing to worry about? My CPU is a AMD Palomino (XP) 2100+. Any
advice would be gratefully appreciated.

Thank you

Do you have a system fan? Typicallly that would be the fan on the
northbridge though it's not always a standard designation, could be
assigned to any fan header on the board OR even be a physical
capability of the hardware monitor chip that has no possible input...
these situations arise a lot when using non-specific monitoring
programs, not something designed by motherboard manufacturer to be
specific to the motherboard.

If you don't have that fan, it'd be a pretty good reason why it has 0
RPM detected, in which case you should just disable that reading.

If you do have a system fan, it needs have the RPM lead, 3rd wire,
going to the plug... today motherboards still can't sense RPM from
only two wires, at least none that I'm aware of.

If you have the fan, with RPM signal, and plugged into appropriate
header, everything seems correct but it still does't work right then
it's RPM may be too low to register correctly, in which case a BIOS
update "might" help (or might not, consult the manufacturer's BIOS
update notes).

Nah, wait till it reaches 100c then stick a pan of water on it...
great for making hot coffee when you don't have a kettle handy ;]]
