Dear customer,
Thank you very much for choosing our NA-FC1. The NA-FC1 is a compact, highly flexible
controller for 4-pin PWM fans that can both work on its own for manual speed reduction and
also work in tandem with the automatic motherboard fan control. Each Noctua product is
double-checked for flawless operation by our quality control team before it leaves the factory
and I’m confident that you will be able to sense some of the research, attention and care we’ve
put into making this device.
Enjoy your NA-FC1!
Yours
sincerely,
Roland Mossig, Noctua CEO
