Thank you for this great idea.
I have a bltouch on pin1 and 2, so which pins should I use for the two 5 V fans? Can I hook them all three on one?

HI DjDemonD, I made a nother sketch just for clearance. Will that work without crashing the mosfets on the always on fans? The 12 V fans don't need much ampere! The ground from the waterpump is connected to ground Fan3 to crontrol it? Is it a idea to put step up converter direct on fan outputs?

Thank's for your quick response, maybe I have to switch the 5 V fans. @ T3P3Tony the arrows are only indicating that the pump and the 12 V Fan belong to the hotend and not that I connect them to E1.
So the the easiest way is to swap the 5 V fans and connect like shown in the new pic. I am just wondering if there is an other option to keep the 5 V fans.

I have a Duet Wifi.
I read that's it's not smart to directly wire a volt converter to the fan outputs. I also read that's possible to get 12 V on the fans by wiring a 12 V step down modul between PSU and the fan jumper. But than I don't know how to control the 5 V fans.

The water cooling is ment to work with a 500 °C dyze hot end. So water cooling pump and the Fan for the radiator should only run when the hotend is in use.
The water pump I am going to install is: https://www.amazon.de/gp/product/B073JRKZBX/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1

Hi Guys,
I'm stucked with my wiring. I red some posts but I am not sure how to do it right. Maybe you can help out. I draw a wiring sketc of my set up.
1 Extruder: 5V Hotend Cooling Fan from Noctua and a 5V Part cooling Fan from Noctua two
2. Extruder: 12 V Waterpump and 12V Radiator Fan cooler

I am using a 24 V PSU and my jumper is set to 5V.
I have 2 step up converter and 1 step down converter.!
