I've got that original Sonata. Recently the case fan has started making noise, so I checked it and yes, it's 'gritty'.
That fan was plugged directly on the PSU, thus the mobo only had the CPU fan plugged onto it.

I decided to change the case fan AND add a system fan (behind the disks). So I picked the Artic PWM12 (http://www.overclockers.co.uk/showproduct.php?prodid=FG-013-AR) for case fan at the back, and the Alaska 18dbA 1400 RPM for system fan.

I plugged the Artic to the 4 pin "System Fan 2" header on the mobo, and the Alaska on "System Fan 1" 3 pin header.

The problem is that the PWM fan doesn't spin. The other one spins continuously and doesn't seem to change speed (as expected) but the Artic doesn't move.. I'd like it to move at least a little to extract from the case !

The documentation mentions that I could use the CPU header to get the PWM, but well I'd like to use the dedicated header of it...

Is there a trick ?
 
Well, I ended up coupling the CPU fan and the Artic extractor one, as they explain is an "alternative" in their document. Now the fan runs at the same speed as the CPU, it's nice and quiet.
I plugged the Alaska (3 pins) on the 4 pins SYS_FAN_2 connector and that one also varies in speed with the temperature !

So I'm all happy now. very quiet machine, and quite a bit cooler than before (especialy the disks !)
