The Bykski N-H200-SR-QH is an all metal Vacuum Brazed GPU water block for the NVIDIA Tesla H200 141GB, cooling the bare die, memory and VRM from one copper plate. Built for cards that run without idle periods.

The cold plate is a single 9.5 mm oxygen-free copper billet joined by vacuum brazing rather than sealed with a gasket, so no O-ring joint sits between the coolant and the card. It carries 48 jet-fed micro-channels at 0.3 mm for 8251.2766 mm² of wetted area, with electroless nickel plating for corrosion resistance.

Warnings

This is a repair or replacement only item. Returns are not accepted on compatibility issues, or once fluid has been run through the block. Confirm fitment before ordering.

The manufacturer may alter the design, so the delivered item may not match the pictured item exactly.

Installation removes the card's stock heatsink, after which the card cannot be air cooled at all. Never power it without the loop installed and the pump running.
