About this part
Full-coverage GPU water block with backplate for the cards listed under Compatibility. One block covers the GPU chip, the memory and the power stages in one pass. Fitting it removes the stock heatsink, so the loop becomes the card's only cooling path.
The T2 copper cold plate is electroless nickel plated and has a 0.35 mm base, with 0.3 mm jet channels that carry heat into the coolant. A nickel-plated copper top and an aluminum backplate hold the board for continuous use.

Thermal pads: 1.5 mm, 5 pieces
Washers: 0.5 mm, 4 pieces
Spring screws: M2 x 5 mm, 4 pieces
