[//] Precisely Matched for ≈ 800W

Native support for system TDP ≈ 800W. Features a 480×120×60mm slim radiator + 4× 120mm fans – more surface area and airflow than any high‑end air cooler, perfectly sized for single/dual‑GPU mid‑load scenarios without overkill.

[//] Stable & Quiet

The D5 pump & reservoir combo delivers ample flow with integrated air bleeding and easy filling – far more reliable than cheap AIOs or low‑flow pumps. EPDM tubing with barb fittings + hose clamps ensures leak‑free operation.

[//] Full AI Throughput

Oxygen‑free copper micro‑fin water blocks (CPU/GPU) + efficient single‑radiator loop. During long training or rendering sessions, GPU/CPU temps stay under control – no downclocking, no power limits, faster iteration for personal developers.

Target Users & Typical Workloads

// TARGET SEGMENT_01

Multimodal creative studios

Creative teams that need to handle both AI video generation (e.g., Sora‑like models) and 3D rendering. The water cooling system effectively suppresses heat buildup during prolonged full‑load operation, protecting expensive core hardware.

// TARGET SEGMENT_02

Small AI startup teams and labs

In the early stages, expensive data center hosting fees represent a significant burden. This solution allows teams to develop and fine-tune models 24/7 in a normal office environment, without being constrained by server room air conditioning. The silent operation of the D5 pump ensures no disruption to daily work.

// TARGET SEGMENT_03

Independent AI developers and researchers

For those pursuing "local compute freedom," 32GB of VRAM (e.g., RTX 5090) combined with the extremely low temperatures of a custom liquid cooling loop ensures that when experimenting with different hyperparameter combinations, the system consistently runs at peak frequencies—avoiding training delays caused by thermal throttling.

// TARGET SEGMENT_04

Custom hardware solution providers

For business owners selling high-end PCs or AI servers, this solution serves as an outstanding "technical business card." Its sleek EPDM industrial aesthetic, paired with meticulous cable management and 8K‑grade commercial photography, quickly builds a "professional, reliable, and high‑end" brand image, attracting government and enterprise clients who value quality.
