800d build help

[fantasticCG]

My new build is the 800d case and I have the asus maximus iv extreme z mb
. My question is the fans the 800d come with are 3 pin. My mb has 8 optional fan connectors
There all 4 pin. Can I still put the 800d fans in them? Help please guys thanks.

You can, there is a plastic tab on the four pin headers that will guide the three pin fan connection onto the correct 3 of 4 pins.
