Hi
I want, need use an 5V Noctua Fan on my Laptop while I am travelling for that I search on Ebay and Aliexpress for an USB Controller but I could not found anything satisfied.  :-//
Does anyone know a Product who allow me to use an 5V USB Output or maybe an USB-C Powersupply to power and control an Fan?
Thanks

So, you have a 5V fan that you want it powered from your laptop. Simply try soldering the fan to a classic USB cable. should work just fine.

An isolation circuit is not required for this kind of a simple task. You just need to apply +5VDC to the fan.
Usually in modern computers, the usb port is protected from short circuits and overloads.
I believe that noctuca fans are quite good quality and you shouldn't have any issues connecting them to the USB. all you're asking is a way to complicate what is simple.  :-+

A 2s google finds these:

But they are designed to run 12V fans. So either get a 12V fan, or run the fan directly from USB as Shay said.

If you are paranoid about damaging your tablet, then use a powerbank.
