Quickly obtain goods as usual with Amazon Prime, unfortunately the fan seems to be a Monday model. After mounting a third fan on my Alpenföhn K2 teamed up ... absolutely nothing. Multiple reconnected and rebooted to produce no reaction. Neither the connection of (functioning) CPU Fan, still 3Pin Casefan connection (what should also work, then only without PWM modulation), nor directly with the included adapter directly to the power supply.
