Hi Paul, I have actually settled for the 9500ALED, which is great (and I knew
for certain that it is comptaible with my hardware - wasnt aware of any three-
pins being compatible) and I think comes with its own fan mate. I also would
like to attain fixed full speeds with my fan, and noise is not an issue for
me.
How would I be able to deactivate the PWM signal if I had a fan mate, yet
still wanted to use the pin?
Thanks in advance.

You should be able to deactivate the PWM feature, in the BIOS. It depends
on what it is called. On an Asus board, fan control is called Q-Fan.
I suppose the hardware would also be accessible by Speedfan, so even if a
BIOS setting disabled something like that, it is possible an application
at the OS level, could still control it.
There is another way to power a CPU fan. This item illustrates the concept.
There are three connectors.
The 1x4 Molex, is a source of +12V and ground. It connects to the 1x3 male on
the right.
The yellow wire is the tachometer signal. The yellow wire goes to the female
in the middle. By connecting the female to the motherboard CPU header, the
motherboard gets a tachometer (RPM) signal, and that will prevent the BIOS
from becoming upset because there is no RPM signal.
The three pin male on the right, would connect to the Fanmate, and from the
Fanmate, you connect to the fan. Depending on what is on the end of the
Fanmate for a connector, there might still be an issue. That Startech cable
is expecting the fan to have a three pin connector, and the plastic shell
is meant to prevent an accident if the right most connector were to fall
onto the motherboard. The plastic shell prevents the 12V pin from touching
something. So that adapter cable won't solve all problems, but it does
illustrate the concept of delivering the RPM signal (yellow) to the
motherboard's CPU fan header, to prevent problems.
I have a local electronics store, that happens to have some kits so I can
put fan connectors on the ends of wires. In some cases, I'd had to make my
own cabling. All part of the fun...

Thanks again Paul - I think I'll deactivate the signal and let the fan mate
regulate the fan speed or I may keep it fixed at 2600 rpms. I'll also have a
look at the three-pin concept in the link you sent me..but hopefully
installation of the fan wont be too difficult when i finally get it.
Microdirect decided to delay their dispatch of the fan so i have to wait
longer. Thanks again for your help.
