The Heatkiller GPU-X³ 79X0 Radeon HD 7970 Full Coverage Water Block has a unique design helping to keep your card cool. The flat design and top quality materials are the main features of the GPU-X³ series blocks. The water-carrying part is made completely of high grade copper. In addition to the graphics processor, the voltage regulators are cooled as well. In the area of GPU a particularly fine micro structure was built. Together with a small residual soil strength optimum cooling performance is achieved. In all relevant areas of insulating spacers were inserted. These make for easy installation of the cooler.
To keep the flow resistance, and the overall weight down, all channels are running large volume. Due to the existing thread on both sides of the terminal block the block can be installed in series and other configurations.
For ease of installation, all supplied thermal pads are pre-cut.
Block does NOT fit the 7950 reference design.

so i bought one of these to see if it would fit my 7950 cuz some websites said it would i got it and it didnt. however it was so close that i went out to my machine shop and made the 2 small modifications to make it fit, this all went on 2-3 weeks ago now frozen comes up with the 15022 that is made to fit my card now i have no warrenty on the one i bought but comparing the 2 where the differences were it looks like i made the same mods, kinda frustrating but it works great i have 1 card with this cooler and 1 aircooled after playing crysis 3 for an houri cant touch the air cooled one which reads 70c+ but the one with this on it i could hold my hand on all day at 37c so pretty big difference. even with my cpu on that loop the hottest i have seen it is 38c
Baddest block out there!

I wish I saw this before I got the Swiftech Komodo waterblock. The Komodo really sucked, didnt cool well at all, I replaced it with this and now my temps are under control. This thing is absolutely perfect, amazing build quality and looks sexy.
Excellent block

Great build quality and craftsmanship and is packaged very well. Attention to all the little details shows with all of the heatkiller products I''ve used. I won''t use another brand. Period.
The chrome backplates look very nice and are a nice addition.
