How can i connect another case fan?

[Fer DLC]

My mother board only has 3 chassis fan connectors and i wanna connect a fourth case fan, how can i do this if my motherboard doesn't have an extra connector?

you can use a fan splitter for that header, meaning those 2 fans will be controlled by one header ;
