Hello,

I am hoping to connect a couple pc fans to a fan speed controller, and have it powered with a 12v adapter. I am hoping to do this cheaply, like possibly buying off ebay.

Below is a picture of the fans I already bought, but finding the right connections to speed controller has been a real challenge.

Thank you in advance :)

Hi :) 

Umm those fans have only 2 leads...no speed control lead...it wont work...the best you will be able to control is ON or OFF...

All the best Brett :)

Thank you for both responses.

@Brett92S@ - Since I need to buy new fans (if I want speed control) what should I look for in purchasing new fans?

Hoping to find some cheap ones on ebay.....:)

You don't need to buy new fans to have speed control.
Speed control is obtained by raising and lowering the voltage , that's what the fan controller does.
You won't know how fast or slow the fans are going because there's no rpm cable.
