[Core V71 issue]

Hello,

Today I decided to install the fourth optional 200mm fan on top of the tower. I used a 4 pin V-spliter and everything works pretty well except one thing-I can't turn on or off the fan leds, it seems that that specific button doesn't work!

What should i do?

BTW

I tried reversing the tower back to 3 200mm fans and the button still wont work.

 

Thanks and sorry for my english im not an american.
