Common Applications
The N-GY4070TIXY-X is a full-cover GPU water block matched to the PCB layout of the Galax (KFA2 in EU regions) RTX 4070 Ti, 4070 Ti Super and 4070 Super Boomstar OC. The cold plate is nickel-electroplated high-purity copper that contacts the GPU die through thermal compound while pre-cut thermal pads transfer heat from GDDR6X memory and VRM stages to dedicated raised pads on the block. The matching black backplate dissipates rear-side heat from the memory and PCB. Top and bottom G1/4 ports support both serial and parallel multi-GPU plumbing, and the included A-RGB strip runs on a standard 5V 3-pin header.
Frequently Asked Questions
Q: Which cards does this block fit?
A: Galax (KFA2 in EU) GeForce RTX 4070 Ti Boomstar OC, RTX 4070 Ti Super Boomstar OC and RTX 4070 Super Boomstar OC. The reference PCB layout is shared across these three Boomstar SKUs.
Q: What is the cold plate material?
A: High-purity copper with a nickel electroplated finish to prevent oxidation in long-term contact with PC coolant.
Q: What lighting standard does the block use?
A: 5V 3-pin addressable RGB (A-RGB / RBW). Do not connect to a 12V 4-pin RGB header or the LEDs will be damaged.
Q: How many G1/4 ports are on the block?
A: Four. Top and bottom inlet/outlet pairs allow serial chaining or parallel splitting in multi-GPU loops.
Q: What ships in the box?
A: Block, matching backplate, mounting screws and spring screws, insulation spacers, thermal pads pre-cut for memory and VRM, thermal paste and port plugs. Fittings are not included.
