Hope someone can help.

I initially had some trouble getting the fans to work. Finally they can operate however this is with the jumper set to "Low Power". This is a little strange but atleast they have power.

The fans are Papst 4412 F (120mm - 12RPM at 100%) of which I have 3 (one on each channel). I have the divider set to 1 (Have tried all of the others which report back different RPM's). If I am to trust the rpm that is displayed then they are operating at about 1/3 (484) of the speed even though I have them configured to operate at 100%

Hi zr_ox,

Thanks for posting at the forums.

To get your fan to work at full potential, you will need to set the jumper to high power. You will also need to apply external power, using an unmodified floppy cable, into the power connector that is located right under the fan high/low power jumper select. You will be able to use the unmodified floppy power connector located on your PC's power supply. For more detailed information on powering the fan headers, you can refer to section 2.2.2 of the manual located at http://www.matrixorbital.com/files/LK202-24-USB_02.pdf .

If you have anymore questions or concerns, please feel free to contact me.

Best Regards,
