GA-K8NS Ultra-939 & AMD fan

[Guest]

Archived from groups: alt.comp.periphs.mainboard.gigabyte (More info?)

I just bought the GA-K8NS Ultra-939 along with an Athalon 64 3000+ in
a retail box w/fan. When I hooked everything up, the CPU fan died
after about 10 sec. at the second POST screen. I took it back to the
vendor and after a lot of experimentation, and our 3rd GA-K8NS mobo,
we figured out that the fan pins closest to the CPU wouldn't support
the fan. When plugged into the fan connector on the MB closest to the
IDE controller, it works.

I'm not near the board now, but here is my question. The fan is an AMD
fan that came with the processor. Shouldn't the fan pins near the CPU
slot support this fan? I believe the other fan pins on the board are
marked "Power fan," and "System fan." What are the differences? Is it
a good idea for me to have the CPU fan plugged into the "Power Fan"
connector?

Common problem with this board not the fan. The header near the IDE
sockets doesn't have a sensor (manual pg.24).

Fixes:
1.Disable CPU Smart Fan control in BIOS/PC Health Status
2. Others have recommended using a converter from the header
connector-4 prong connector-power supply.

I am using fix #1

I'm at work, but I'll have a look at the manual later. Seems kind of
strange though that the Smart Fan controller would turn the fan off
while the chip was heating up during a boot. Any clue as to why?
Anyways, thanks for your reply to this message.

The "Smart" Fan Control is supposed to decrease fan speed when the
temp is below 40 C, not stop it which it seems to be doing on many
boards. When you attach the fan to the header without the sensor the
fan control does not come into play.
