When we first reviewed the original 3d Galaxy water cooling kit, we were pleasantly surprised at the ease of installation and how well it performed. Gigabyte has made a number of great changes to the second version of this kit, perhaps the most important is the increase in tubing size from 3/8" to 1/2". The means by which the water block is attached to the socket LGA 775 is a vast improvement over the first model. So come on along and check out this very slick water cooling kit
