Can be helpfull to add that all the fans are using the micro PH2.0 2P connectors.https://www.sparkfun.com/datasheets/Prototyping/ePH.pdf
For the V2 with Mega-S, quoted:
"For easier installation (no wire cutting), I bought this adapter:
3to2pin Adapter [Amazon EU/DE]
3to2pin Adapter [Amazon US]"
In my case this adapter cannot be connected to the PSU mainboard as it is 2.54 not 2.0.
I did my wiring directly from the fan using a 2.0 connector.
I think this may work:https://www.amazon.de/L%C3%BCfter-Adapterkabel-2-Pin-3-Pin-Molex/dp/B01JP6QHB0
