FAQ:

Q: Is there a 4 pin Molex fan converter?

A: This is the most number of fan connectors to one Molex I found, and it works well for the 2 extra case fans I have that are 120mm and ~1000 RPM. Its decent quality and it was great that the connectors support 3 or 4 pin. Just know that the converter only provides 2 pins per fan.

Q: How many pins do you need for a PSU fan?

A: Only 4 pins are available on the motherboard but my case PSU only has 3 pins for fans. and everything was fine for me. So it is a bit pricey for what it is but it is not the end of the world for 7 bucks. Cheap way to juice multiple fans.

Q: Which is the third pin on a HD power adapter?

A: The only issue some user might find challenging is that it’s using the first 12v pin not the second, and most HD power adapters uses the 3rd pin (second 12v pin). It is very simple to move the pin from second to third, just need the correct tool.
