Common Applications

The B-FRD-TESLA-L4 is a sealed AIO designed to give the passively-cooled NVIDIA L4 inference accelerator active liquid cooling in a workstation or tower chassis that does not provide server-grade directional airflow. As a B-FRD-series product it is a closed loop pre-filled at the factory, including a pump, radiator, tubing and a full-cover GPU block built around the L4's PCB layout.

Frequently Asked Questions

Q: Why does the NVIDIA L4 need an aftermarket cooler?

A: The L4 is a passively-cooled card that relies on directional high-static-pressure airflow from a 1U/2U server chassis. In a standard desktop or tower the card has no fan and will throttle without help.

Q: Which L4 cards are compatible?

A:  NVIDIA L4 processors. The block is not for the Tesla T4, Tesla P4 or NVIDIA L40, which are different PCBs.

Q: Is the loop sealed or a custom loop?

A: It is a sealed AIO, factory pre-filled. No coolant or fittings are required before installation.

Q: What thread does the block use?

A: Standard G1/4 inch ports on the block side.
