A MetaX CPU liquid cooling plate is a direct-to-chip thermal management solution specifically designed for MetaX (沫铨科技) domestic GPU and AI accelerator processors — including the MetaX C500, C280, and N100 series — used in China’s self-developed AI computing infrastructure. The liquid cooling plate mounts directly on the MetaX processor die surface, circulating coolant through internal micro-channels to remove 200–400W of heat per chip while maintaining junction temperatures below 85°C. ToneCooling manufactures custom MetaX CPU liquid cooling plates with vacuum-brazed copper or CNC-machined aluminum construction, achieving thermal resistance below 0.06°C/W at 1.5 LPM coolant flow rate. Prototype delivery in 7–15 business days (MOQ 5 pcs), with production capacity for hyperscale AI server deployments.

What Is MetaX and Why Does It Need Liquid Cooling?
MetaX (沫铨科技, Shenzhen, China) is a domestic GPU and AI accelerator manufacturer producing processors designed to replace NVIDIA in China’s AI computing ecosystem following US export restrictions. MetaX chips — particularly the C500 (comparable to NVIDIA A100) and C280 series — generate 200–400W TDP, requiring direct-to-chip liquid cooling for reliable operation in dense server deployments.
The shift to domestic GPU suppliers creates unique thermal engineering challenges:
- Non-standard die sizes: MetaX processor packages differ from NVIDIA/AMD footprints, requiring custom cold plate mounting designs
- High power density: 200–400W in compact BGA packages produces heat flux exceeding 30 W/cm²
- Rack density requirements: Chinese AI data centers target 60–100kW per rack, impossible with air cooling alone
- Supply chain independence: Domestic AI infrastructure requires China-based thermal solution suppliers like ToneCooling

How Does a MetaX Liquid Cooling Plate Work?
A MetaX CPU liquid cooling plate operates through three thermal transfer stages:
- Conduction: Heat transfers from the MetaX processor die through a thermal interface material (TIM) — typically indium solder or high-performance thermal paste (8–12 W/m·K) — into the copper or aluminum cold plate base. Contact thermal resistance: <0.01°C/W.
- Convection: Coolant (water-glycol mixture per ASHRAE W55 water quality guidelines) flows through internal micro-channels at 0.5–2.0 LPM, absorbing heat through forced convection. Channel hydraulic diameter: 0.5–2.0mm.
- Heat rejection: Warm coolant exits the cold plate and flows to a CDU (Coolant Distribution Unit) or rear-door heat exchanger where heat is rejected to facility water or ambient air.

Domestic Chinese GPU Liquid Cooling: Market Context
Following US semiconductor export restrictions (October 2022, updated October 2023), China’s AI computing industry is rapidly adopting domestic GPU alternatives. Key domestic GPU manufacturers requiring liquid cooling solutions include:
- MetaX (沫铨): C500 and C280 AI training/inference accelerators — ToneCooling’s primary domestic GPU cooling partner
- Biren Technology (壁仍): BR100 and BR104 general-purpose GPUs for AI and HPC
- Moore Threads (摩尔线程): MTT S80 and S4000 series for AI inference and gaming
- Huawei Ascend: Ascend 910B and 910C AI training processors
- Hygon (海光): Deep Computing DCU series for scientific computing
This domestic GPU expansion is projected to drive $2+ billion in liquid cooling demand by 2027 (per IDC China AI Infrastructure Forecast), as data center operators transition from air cooling to direct-to-chip liquid cooling to support 60–100kW rack densities.

Frequently Asked Questions: MetaX CPU Liquid Cooling
What is a MetaX CPU liquid cooling plate?
A MetaX CPU liquid cooling plate is a direct-to-chip heat exchanger designed for MetaX (沫铨) domestic GPU/AI accelerators (C500, C280, N100 series). It circulates coolant through internal micro-channels to remove 200–400W of heat, maintaining junction temperature below 85°C for reliable AI server operation.
Why do MetaX GPUs need liquid cooling instead of air cooling?
MetaX GPUs generate 200–400W TDP in compact packages, producing heat flux exceeding 30 W/cm². Chinese AI data centers target 60–100kW per rack density, which is physically impossible with air cooling (limited to 15–25kW per rack). Liquid cooling achieves 10–20x higher heat removal capacity.
Does ToneCooling support other domestic Chinese GPU brands?
Yes. ToneCooling manufactures custom liquid cooling plates for MetaX, Biren Technology, Moore Threads, Huawei Ascend, and Hygon DCU processors, as well as international platforms including NVIDIA GB200/H200 and AMD EPYC SP5.
What is the thermal resistance of ToneCooling’s MetaX cold plate?
Standard aluminum CNC: 0.08°C/W at 1.5 LPM. High-performance copper vacuum brazed: 0.05°C/W at 1.5 LPM. Both configurations support 50/50 ethylene glycol-water coolant per ASHRAE W55 guidelines.
