4-Pin sytem fan connector on my motherboard?

I bought this motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130275

And this power supply http://www.newegg.com/Product/Product.aspx?Item=N82E16817182133

The power supply is modular and came with two Molex cables that have four molex connectors and at either end is the PSU plug-in and at the other end is what I assume to be where you should be able to plug it into the motherboard but I cannot for the life of me find a 4 pin sys fan connector on the motherboard! there is a 3 pin one in plain sight but no 4-pin as far as I can see :(

My fans running at full speed makes the case very noisy and without finding a place where I can plug in the 4-pin connector there's no way I can fix it D: please help!
