Hello NG guru's,

The fans in my system start full speed and keep doing so all the time
(cpu-case and powersupply) resulting in a little to much noise.
Anyone know a solution for this???

How much do you want to spend?
Try an aftermarket fan, but with more powerful CPUs, fan noise this is
pretty much par for the course these days.
If you have your PC case on the top of the desk try putting it under the
desk.

For an idea of what is available, try www.quietpc.com. The Zalman
coolers are very good. There are alternatives - I bought a nexus quiet
power supply from www.novatech.com which has helped a lot

I leave the side panel off on my K8V, otherwise the fan makes too much
noise. It's just poor ventilation in the case - cheap case. Of course better
ventilation means more fans so leaving the side off is a good compromise.

On systems that feature "Q-fan", the CPU fan speed is controlled
by the measured CPU temperature. The fan ramps up at around 50C
or so.

On systems with "Q-fan2", more than one fan in the system is
controlled as well.

Some systems have no fan speed control at all. Your motherboard
could be one of those.

For the PSU fan header on the motherboard, generally that header
is provided just for monitoring the RPMs of the PSU. If a PSU
has one fan connector, it is for monitoring and not control.
Only one wire of the fan is being brought out of the power supply,
and the power supply still controls the voltage delivered to
the fan itself.

Many third party fan control solutions, provide simple voltage
adjustment. (The technical terms are "fan bus" or "rheobus".)
The simple voltage adjustment means you can increase or reduce
the fan speed, but the fan speed doesn't change with temperature.
For example, I have a couple of Zalman FanMate controllers,
and these have three pin interfaces on the ends of the module,
to plug into the motherboard and to the fan. That gives the
ability to adjust the fan manually.

There are a few devices which have temperature sensors and
can control the speed of connected fans. This article had
a roundup of a whole bunch of different devices.

This device is fully automated, or so it is claimed.
One would hope that means it uses a different temperature
profile for each fan, as a CPU fan should turn on at a
higher temperature than a case fan. The case fans should
ramp up before the CPU fan does.

This device is programmable via a serial port:

One comment at the end of the article is still true today -

"It is shocking what kind of junk there is out there to buy.
Only 30% of the devices tested are worth paying for."

Bear that in mind when shopping for one of these devices.
You can check the user review section of Newegg, for some
of the products, and when I did that in the past, some
users reported early failures for their fan controllers.

HTH,
