The Bykski Durable 360mm Server AIO Liquid GPU Cooler is a single-card kit: one full-coverage water block on a sealed loop with a 360 mm radiator. It arrives pre-assembled, pre-filled, and pre-bled. It requires no opening, filling, bleeding, or topping up, offering out-of-the-box liquid cooling performance.

For passively cooled server cards like the NVIDIA TESLA L40, stock cooling relies entirely on chassis airflow. This AIO kit removes the card's dependence on front-to-back air, effectively moving die, memory, and VRM heat directly to the chassis wall, ensuring stable operation under high load without requiring additional chassis fans for the GPU itself.

The pump sits off the block on its own mount rather than on top of the die, so nothing vibrates against the card and the pump can be reached without disturbing the block. The loop ships pre-filled and pre-bled - no filling, no bleeding, nothing to top up.

Warnings

This is a repair or replacement-only item. Returns are not accepted on compatibility issues - confirm the card before ordering. An unused kit comes back within 30 days, no questions asked; a kit that has been installed can still come back, but a higher restocking fee applies.

The loop is sealed, pre-filled and pre-bled. Do not open it, do not modify the tubing and do not attempt to top it up. Doing so voids the warranty and can cause a leak or a pump failure.

Removing the stock cooler from a passively cooled card means it can no longer run on chassis air. Do not power the card without the kit installed and the pump running.

Fitting the kit means stripping the card to the bare die. Thermal pads go on memory and VRM; thermal paste goes on the die.

The manufacturer reserves the right to alter the design to expand compatibility, so the delivered item may not match the pictured item exactly.
