EK Radeon HD 4850 and 4870 waterblocks update

EK Blocks has added full cover 4850 and 4870 waterblocks in a variety of finishes to its website. It appears EK are sticking to the two-piece design with the main copper part cooling the RAM and core while a separate screw-on section cools the VRMs. Unlike the HD3850 and HD3870, the 4850 and 4870 are quite different beasts requiring slightly different VRM sections. The 48xx series cards are crying out for watercooling with the reference coolers getting red hot even at idle. Thankfully Eddy has come to the rescue! Images courtesy of www.ekwaterblocks.com
