A Desk-Side 4-GPU Water-Cooled Box? TFNEW ZT-4201-LC
TL;DR: TFNEW launched the ZT-4201-LC, a 4-GPU tower liquid-cooled workstation, on September 21, 2026. With 2x Intel Xeon 6530, 1 TB of RECC DDR5, 4x RTX 5090 32GB and a custom liquid-cooling kit (4x 480 mm radiators, CDU control center), it puts 128 GB of VRAM and full-sustained GPU clocks in a 636 mm-deep tower for local training, simulation and rendering teams.

Core Specifications (with Plain-Language Terms)
The ZT-4201-LC is the 4-GPU member of TF NEW's liquid-cooled tower workstation family: the GPU-count that fits on a bench (L636 × W300 × H570 mm, desk-side) while still needing liquid cooling to sustain flagships quietly. Compute is 2x Intel Xeon 6530 (32 cores, 64 threads each, 2.1 GHz) with 16x RECC DDR5 64GB 5600 MT/s modules (1 TB total). The custom liquid-cooling kit covers the same architecture as its big sibling — radiator, water distributor, quick-release fittings, pump, tubing, CPU water blocks and GPU cold plates, plus a CDU control center — sized at 4x 480 mm radiators with 4 silent fans. GPU: 4x RTX 5090 32GB — 128 GB of VRAM. Power is 1x 3000 W plus 1x 2000 W ATX. Networking is a 25 Gb dual-port NIC with 2x 25 Gb multimode optical modules; onboard is 2x gigabit RJ45. A 7-inch LCD shows loop and system status.

Why Four Cards in a Bench-Sized Tower Is the Sweet Spot
Eight-GPU towers win the headline; four-GPU towers win the office. The ZT-4201-LC is sized for the desk-adjacent team that needs 128 GB of VRAM and Xeon-class CPU power without the footprint or the power budget of an 8-card rig. The water loop — four 480 mm radiators and four silent fans — keeps the 5090s at sustained boost clocks, and the CDU control center with a 7-inch LCD makes the loop a managed subsystem rather than a hobbyist project. It is the liquid-cooled workstation for teams that have real training and rendering loads, but a finite desk.
Where It Fits
- Local training and fine-tuning: 4x RTX 5090 with 1 TB RECC DDR5
- Rendering and VFX benches: 128 GB VRAM on a desk footprint
- Simulation and analysis: dual Xeon 6530 for CPU-bound solvers
- Labs with space constraints: bench-sized liquid cooling with server-grade reliability
Why the Numbers Matter
- 4x RTX 5090 32GB: 128 GB VRAM for local models at full precision
- 1 TB RECC DDR5: registered ECC memory for long-running jobs
- 4x 480 mm radiators + CDU: sustained clocks on a bench-sized loop
- 3000 W + 2000 W ATX: headroom for dual Xeon and four flagships
- 25 Gb dual-port NIC: cluster-class networking from a tower
What TF NEW Says
"Not every team needs eight GPUs — but every train-and-render team needs sustained performance," said a TF NEW product manager. "The ZT-4201-LC gives four RTX 5090, 1 TB of RECC DDR5 and dual Xeon 6530 in a 636 mm tower under a four-radiator liquid loop with a CDU. It's the workstation where 'fits the desk' and 'runs flat out' stop being opposites."
Quality and Availability
Every ZT-4201-LC is pressure-tested and burn-in validated — CPU, GPU and coolant loop run 48 hours under full load before shipping, with leak-tested fittings and documented loop maintenance. It ships deployment-ready with a 7-inch LCD management guide.
