Common Applications
The HG-DCUK100-SR is a full-cover water block built for the HYGON DCU K100 AI accelerator card, contacting the compute die, HBM/VRAM stacks, and VRM power stages from a single nickel-plated copper cold plate. The top is POM, which holds up under continuous high-temperature operation typical of AI training and inference servers, and the inlet/outlet ports use the standard G1/4 thread so the block plugs into a conventional PC or workstation water loop. It is aimed at deep-learning workstations and lab rigs where the DCU K100 runs near full utilization for long stretches and stock air cooling becomes acoustically or thermally unworkable. The block is also available as part of Bykski's matched B-FRD-HG-DCUK100 all-in-one bundle with a 240/360 radiator and pump.
Frequently Asked Questions
Q: Which accelerator does this block fit?
A: The HYGON DCU K100 AI accelerator. The PCB pattern and cold plate are tailored to that card; it is not a universal block.
Q: What materials are used?
A: Nickel-plated copper cold plate with a POM top. POM holds up under sustained high-temperature operation in AI server racks.
Q: What thread are the ports?
A: G1/4, the standard PC water-cooling thread, so the block integrates with any Bykski or Barrow fittings, pump, and radiator.
Q: Is an AIO version available?
A: Yes. Bykski sells a matched B-FRD-HG-DCUK100 all-in-one kit that pairs this block with a 240 or 360 radiator and pump.
Q: What workloads is it built for?
A: Sustained AI training and inference runs on the DCU K100 where the card operates near full utilization for hours at a time and air cooling becomes the limiter.
