Common Applications
The FBLTFHAT-04N V2A is built for AMD Ryzen Threadripper processors on the TR4 and sTRX4 sockets (X399 and TRX40 motherboards), with a full-coverage footprint sized to the rectangular Threadripper IHS. The copper cold plate carries a 0.4mm microchannel array with mirror-polished nickel plating and dense fins to cope with up to 64 Threadripper cores. An on-block TFT screen reports coolant temperature in real time, and the lighting consolidates onto one 5V 3-pin LRC 2.0 connector for daisy-chaining with other Barrow components. Two G1/4 threaded ports accept any standard custom-loop fitting.
Frequently Asked Questions
Q: Which AMD sockets are supported?
A: AMD TR4 and sTRX4. Compatible Threadripper families include 1000, 2000, 3000 (X399) and 3000WX/Pro on TRX40.
Q: Will this fit AM4 or AM5 Ryzen?
A: No. This block is sized to the rectangular Threadripper IHS and the TR4/sTRX4 retention holes. AM4/AM5 users need a different Barrow/Barrowch block.
Q: What thread size are the ports?
A: Two G1/4 threaded ports. Compatible with any standard G1/4 compression, barb or quick-disconnect fitting.
Q: Is the ARGB lighting 5V or 12V?
A: 5V LRC 2.0 only. Connecting to a 12V RGB header will burn out the integrated controller. Use the included 5V 3-pin adapter for motherboard sync.
Q: What materials is the block made of?
A: Nickel-plated copper cold plate with 0.4mm microchannels, acrylic (PMMA) middle layer and anodised aluminum top panel.
