Gigabyte 6850 HD fan replacement.

Hello
I have a gigabyte 6850 HD graphics card, its not under warranty anymore. its cooling fans are almost dead and I'm looking for replacement, they are 2 pin fans.
i looked for replacement but I only found 3 pin fans (they are the same type of fans, the connecting pins are not the same.)
Are there any adapters of any kind that i can use to connect the 3 pin fans to my graphics card?
This is my current fans

As you can see they are the same type, but with different connectors.
