Does Cool'n'quiet control K8n Neo2 chipset fan?

My nvidea chipset fan appears to be running at full speed although
Cool'n'quiet is working for the CPU speed and CPU fan control. Should the
chipset fan be controlled on my MSI K8N Neo2 Platinum?

Cool N' Quiet adjusts FID and VID (multiplier and voltage value)
as a function of measured system load. If the system is "idle",
then CNQ uses the minimum multiplier and Vcore voltage. If the
load on the system is 100%, then the FID is adjusted to the maximum.
Adjustments are made on frequent intervals (like perhaps every time
the task scheduler runs).

Fan control is completely separate from CNQ. A fan may have its own
built-in control method (like the thermistor in an Intel fan that
makes the Intel CPU fan sensitive to computer air temperature). A
fan can run at a constant speed (because no control method is
enabled, or because there is no power transistor next to the fan
header, to adjust the voltage).

The Super I/O chip has temperature measurement channels. It also
has automatic or manual fan speed control options. BIOS code or
an application, can access the registers on the Super I/O, and do
some form of temperature based control. But if the fan headers
don't have a power transistor, to turn the Super I/O fan control
signal into something the fan can use, then the fan will be stuck
running at 100% speed. Many motherboard makers won't spend the extra
money to put a power transistor on each and every fan header. Some
premium boards only have two controlled channels.

An example of a program for controlling the fans, is SpeedFan from
almico.com . But SpeedFan can only work, if the power transistor is
present on the fan header. SpeedFan can pretend to adjust all the
fan control channels it sees in a Super I/O chip, but without the
necessary power transistor, the adjustment would be for nothing.

The chipset should have a more constant thermal load, than other
parts of the system. So there might be less reason for a control
system, to be adjusting the speed. The heat dissipated on the Northbridge,
would be proportional to the number of interfaces that are enabled on
the chip. For example, chipsets that have dual channel memory, run
cooler if only one channel is operating. It is possible to disable
the other channel, if it is known, by probing the SMBUS, that no DIMMs
are present, and the clocks and interface busses can be disabled
as a result. Similarly, a Northbridge may have 21 PCI Express lanes
terminating on it, and the more lanes that can be disabled, the
cooler the Northbridge would run. Some chipsets are now at the
20W level, meaning a fan is an excellent idea, if the heatsink
used is a cheap one. Without a fan, in a case like that, the chip
is going to boil. Even motherboards with exotic passive cooling
methods, still rely on "spill air" from the CPU cooler, to help
with the cooling. That is why some motherboards include auxiliary
clip-on fans, for users who make extensive use of water blocks and
water cooling.

Northbridges are also affected by overclocking. Some Northbridges
seem to track the multiplier being used on the processor, and the
internal Northbridge clock is influenced by the overclocking choices
being made. Some motherboards also allow changing the voltages used
on the Northbridge and Southbridge, which again could make a difference
to how much cooling was required.

Chances are, if you remove the fan from your Northbridge, the chip
may end up running too hot. If you want to replace it, try something
like one of these. These still benefit from spill air from the
CPU or other fan. Convection may not be enough.

Paul,

Thanks for the compehensive reply. I was not aware that the fan control was
separate from cnq. I have the Nvidia Nforce2 chip which I believe is a
combined Northbridge and Southbridge. I may put a simpler heatsink on it
with a larger and slower fan. I have the same high speed noise problem on
my graphics board. Its makes me smile when I see products advertised as
"low noise" yet they have high speed fan with ball bearings instead of slow
speed with sleeve bearings.

thanks,

Beemer

I have removed the small cr*ppy noisy fan on my k8N SLI with a Zalman
passive heatsink. The noise was too much to bear - on a $250 Mobo. Works Ok
for 2 years now. I suggest you do the same. Watch out for the heatsink
touching ANYTHING else...
