Hi, I just purchased the ASUS Crosshair IV Formula AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard from newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16813131644 and this is replacing a board I had bought earlier last month that I am replacing..

I have the Corsair H-50 cpu cooler how ever I just noticed the board only has 4 pin cpu fan plugs and on the H-50 there are 2 fan plugs 1 being a 4 pin and 1 being a 3 pin. Will I have to find some sort of adapter for the 3 pin since there are no 3 pin on the board or will a 4 pin allow you to use a 3 pin?
