Question about ASUS Z170 Pro Gaming

Hello Raphi
I have also been looking for a supplier of such a fan extension card for some time. It is not currently on sale at Digitec and cannot be found anywhere else in Switzerland. It seems that Asus is not pushing the distribution of these cards (the product is not even listed as a product on the Asus homepage). Of course, I hope you have more success than me in finding such a card. I would be very interested in a source of supply if you can find one.
Alternatively, I would use Y-cables for the fans, for example this one for 4-pin PWM fans: Phanteks Y-cable for 4-pin PWM fans

so the card is really great, that gives +3 PWM connections + 3 thermistor cables.
