Fan Wire extensions?

Just a couple of questions.

I recently ordered our PC in component form scan.co.uk and set it up this weekend. Included in the order were 2 12cm led fan. Now i have an Asus mobo which supports the adjustable fan speed based on temperature. Currently being controlled is the CPU fan and the front 12cm fan. With the rear 12cm fan on the manual speed control that came with the CPU fan.

What id like to do is this:

Have the front fan on manual control and the rear one on the auto MOBO control, however this isnt possible because the wires dont stretch that far.

Are there any wire extenders for fans in the small 3 pronged male/female connecters?

And also, are there any which branch off into 2, so i can plug 2 fans into one MOBO slot.

thanks.
