AI servers are now cooled by liquid that runs right up to the chip. The part that touches the chip is a cold plate: a metal block with fine channels inside, mounted on the processor, that carries coolant past the heat source. It looks like a small mechanical part. For a risk team, it is a supply chain with a short approved-supplier list, one dominant metal, a new tariff, open chemical rules and a warranty trap.
DC Market Insights values the data center cold plate market at USD 1.78 billion in 2026, up 53.12% from USD 1.16 billion in 2025. A market growing that fast, around a part that sits inside every direct-to-chip liquid-cooled AI rack, deserves a place on the risk register. Here is what to watch.
1. A short approved-supplier list
At GTC 2026 in March, NVIDIA named four approved cold plate suppliers for its Vera Rubin platform. They were reported as AVC, Cooler Master, Delta and Jentech (TVBS News, March 2026). All four are Taiwanese.
For a buyer, this is concentration risk in a plain form. If a server is built around a chip vendor's approved list, the buyer cannot simply switch to another plate maker when one supplier is late, short of capacity or hit by a local disruption. The choice was made upstream.
Some capacity is moving. AVC broke ground on a USD 600 million plant in Vietnam for liquid cooling equipment and water cooling plates in May 2026 (TechNode Global). That spreads the footprint, but it is still one supplier's footprint.
What risk teams can ask: Which plate makers are qualified for the servers we buy? Is there more than one? Where are the plates made, and is there a second site?
2. Copper: one metal, record prices
Copper plates hold 86.0% of 2025 cold plate spend, on DC Market Insights figures. In other words, most of the money in this market goes to plates made of copper, because copper moves heat well.
That ties the part to the copper market. Chile's state copper commission, Cochilco, recorded London Metal Exchange (LME) cash copper at a record USD 14,850 per tonne on 17 August 2026. No public list prices exist for data center cold plates; prices are set in supply contracts with server makers. So the metal price reaches the buyer through contract terms, not a price tag.
What risk teams can ask: Does the contract pass copper price changes through? Is there a cap, a floor or an index? Who carries the risk between order and delivery?
3. A 50% US copper tariff
Since 1 August 2025, the United States has applied a 50% tariff on semi-finished copper products and intensive copper derivatives, under a Section 232 proclamation. Plates for the American market are mostly made in Taiwan, China, Vietnam and Mexico, so US buyers pay the duty on copper-heavy parts.
This is a trade-policy risk that sits on top of the metal-price risk. It can change with a new proclamation, and it can hit landed cost even when the copper price is flat. The report notes that aluminium plates gain share, from 9.0% to 11.0% of spend between 2025 and 2035, partly for this reason.
What risk teams can ask: Is the tariff priced into the quote, or added at import? How is a future tariff change shared? Would an aluminium design meet our needs?
4. Chemical rules for two-phase fluids
Most cold plate spend today is single-phase: the coolant warms up but stays liquid. Two-phase plates, where a fluid boils inside the plate, are the fastest-growing type at 30.34% a year in the DC Market Insights base case. They depend on special fluids, and those fluids face open rules.
- PFAS: 3M said in December 2022 that it would exit all per- and polyfluoroalkyl substances (PFAS) manufacturing, including fluorinated fluids, by the end of 2025. The European Chemicals Agency (ECHA) published an updated universal PFAS restriction proposal on 20 August 2025, and its outcome is still open.
- F-gas: The EU F-gas Regulation (EU) 2024/573, in force since 11 March 2024, phases out hydrofluorocarbons (HFCs) by 2050. Two-phase plates depend on such refrigerants.
For a risk team, this is a regulatory and continuity risk. A fluid that is legal and available today may be restricted, phased down or harder to buy during the life of the equipment.
What risk teams can ask: Which fluid does the system use? What is its status under the PFAS proposal and the F-gas Regulation? What is the vendor's plan if it must be replaced?
5. Coolant care and the warranty
In May 2026, ASHRAE technical committee TC 9.9 issued a bulletin on technology cooling system (TCS) coolant integrity and readiness. It warns that "it is too easy to violate" direct-to-chip warranty requirements.
This is an operational risk with a financial tail. If coolant chemistry, filtration or fill procedures drift outside what the server maker requires, a failure may not be covered. The gap often sits between teams: facilities runs the loop, IT owns the servers, and the contract sits with procurement.
What risk teams can ask: What coolant conditions does the warranty require, in writing? Who tests them, how often, and where are the records kept? Who pays if a reading is out of range?
6. Suppliers are being bought
Large buyers are reshaping the supplier base. Eaton closed its purchase of Boyd Thermal on 12 March 2026 for USD 9.55 billion net of cash. Ecolab closed its USD 4.75 billion purchase of CoolIT Systems on 2 July 2026. Together that is USD 14.3 billion for two cold plate makers. (These were whole-company deals, so the prices are not a value for cold plates alone; we looked at that in more detail in this note on the two deals.)
Consolidation brings capital for new production lines. It also brings change-of-control risk: new owners can change product roadmaps, pricing, support terms or which customers get priority.
What risk teams can ask: Has our supplier changed owner? Do our contracts survive a change of control? Are support and spare parts commitments still in force?
Risk register: cold plates in AI data centers
| Risk | Impact | What to do |
|---|---|---|
| Short approved-supplier list (four named for NVIDIA Vera Rubin, all Taiwanese) | Delays or shortages with no quick switch | Map qualified plate makers per server model; ask for second sources and second sites |
| Copper price (copper plates 86.0% of 2025 spend; LME record USD 14,850/t, 17 Aug 2026) | Cost overrun on contracts | Review price pass-through clauses; agree an index, cap or fixed-price window |
| 50% US copper tariff since 1 Aug 2025 | Higher landed cost for imported plates | Confirm who pays the duty; plan for tariff changes; consider aluminium where it fits |
| EU PFAS proposal and F-gas Regulation (two-phase fluids) | Fluid restricted or hard to buy during equipment life | Record the fluid and its status; ask vendors for a replacement plan |
| ASHRAE TC 9.9 bulletin, May 2026 (coolant integrity) | Warranty claims denied after coolant drift | Write coolant limits into procedures; assign an owner; keep test records |
| Consolidation (Eaton and Ecolab, USD 14.3 billion) | Changes to pricing, support or priority after a sale | Check change-of-control clauses; confirm support and spares commitments |
