My wife received a Corsair H80i for her computer, replacing the faulty one we returned to the retailer.  She's just been installing it this afternoon only to find that the supplied fans are no longer 3 pin, but 4 pin.  The reason this is a problem is because she's using the supplied fans as front intake fans in the Fractal Design Define R4, which has a built in fan controller.  She was plugging in the original Corsair fans into this controller (which has 3-pin sockets for the two fans), but the new fans are now 4 pin, and don't fit anymore.

So - that's the background.  She'd rather avoid plugging these fans direct to the motherboard, and doesn't really want to cut the socket of the fan controller to fit the new 4-pin fans.  Is there such a thing as a converter (4-pin to 3pin)?  I've had a quick look at Jaycar, but couldn't see anything...

The 'Electro Droid' app for android has a note below the information about 3 and 4-pin fan connectors.
"3 and 4-pin versions are compatible: 4-pin can be plugged into 3-pin headers (and vice versa , but lose fan speed control.
