From what I could I would say you would indeed have problems with the first two ram slots. Also depending on your case you may have problems with the height of that cooler as it is 158.5 mm. The cooler is 120 x 79.7 x 158.5 mm (L x W x H) so you should check all dimensions before you order the rest of your parts.
