Report Interpretation
Overview
JPMorgan’s sector report contends that rising AI-chip thermal requirements are driving broader liquid-cooling upgrades across Nvidia GPU and cloud ASIC systems. It sees cold plates, quick disconnects and heat spreaders as key beneficiaries, with AVC and Fositek its preferred Taiwan cooling names.
Core views
JPMorgan argues that cooling, rather than being de-specified, is becoming the bottleneck that enables continued growth in AI-chip thermal design power and AI-server migration. It expects Nvidia’s Vera Rubin Ultra (VRU) to adopt upgrades across cold plates, quick disconnects (QDs), and lids/heat spreaders. The firm expects these changes to deliver larger component-content gains than investors anticipate over the next one to two years, while later liquid cooling in CPO/NPO switches and higher-spec optical modules could add another growth driver from the 1.6T/3.2T generation. At the VRU compute-tray level, JPMorgan estimates cooling content—including cold plates, QDs and inner manifolds—at US$3,000-3,500, 30-50% above the current Vera Rubin design. The proposed double-sided cold-plate architecture is linked to vertical power delivery, which shifts power components, SOCAMM and capacitors to the rear of the chip board and requires backside cooling. VRU could use six cold plates for two Bianca modules, versus two in the prior upper-half tray arrangement, while diamond-copper material around HBM cooling areas adds value. The report also expects eight additional Mini QDs and upgrades of Bianca-module QDs from MQD to ZQD, which carries roughly twice the ASP. JPMorgan models VRU compute-tray QD content at about US$750, versus US$400-500 for Vera Rubin. The tray would retain 22 principal QD positions but upgrade two out-of-tray plugs to ZQD14 and eight Bianca-module QDs to ZQD06, while adding eight Mini QDs. At the 1.5U VRU switch-tray level, two stacked switch boards should require two cold-plate modules and lift total cooling content to at least US$3,000. QD content per switch tray is modeled at about US$260 versus about US$150, reflecting eight internal MQDs rather than four and an upgrade of the two external plug QDs to ZQD14. Across an NVL72 rack, the firm estimates QD content at about US$20,500, compared with about US$11,000 for Vera Rubin and US$9,400 for GB300. The report also expects Rubin Ultra’s removable-lid-plus-stiffener-and-screws design to proceed without delay. It estimates heat-spreader/lid content at four to five times that of the current one-piece Rubin lid, with limited Rubin trial production potentially beginning in 4Q26 and mass production in Rubin Ultra potentially in 1Q27. JPMorgan sees the schedule as somewhat ahead of market expectations and potentially supportive of near-term revenue and earnings for the three-piece-lid supplier. It also identifies AMD MI450’s two-piece lid, with roughly a tenfold ASP increase versus MI350, plus future CPO/NPO adoption and ASIC upgrades as structural support for heat-spreader demand. Cloud ASIC platforms reinforce the argument that cooling content can rise despite lower chip TDP. AWS Trainium 3’s Teton 3 Max system is estimated to generate US$3,000-3,500 of cooling content per compute tray, roughly 30% above Nvidia Vera Rubin, because of eight double-sided cold plates for four ASICs plus a tray-sized baseboard cold plate. With 18 compute trays, 10 switch trays and a rack manifold, total content is modeled at about US$86,000 per rack excluding the CDU, versus about US$66,250 for Vera Rubin NVL72. Google TPU v8 is estimated at US$2,000-2,500 per compute tray and about US$38,000 per rack: its lower TDP is offset by four large gold-plated cold plates for TPUs and eight smaller plates for surrounding ICs. TPU v9, potentially reaching 2,000W, could adopt a removable lid and stiffener; JPMorgan says this remains unconfirmed but views the broader upgrade trend as certain. For stock implications, JPMorgan prefers AVC because its cold-plate and manifold position spans GPU and ASIC projects, which it believes supports better-than-peer margins and earnings growth. It favors Fositek for expected near-term gross-margin upside, increasing ZQD content, share gains and expansion into higher-spec rack-manifold QDs. The firm says both trade at valuations it considers undemanding relative to history and could deliver 3Q26 margin upside and longer-term earnings upside from more substantial specification upgrades.
Analysis framework
JPMorgan compares cooling architectures across Nvidia GPU and cloud-ASIC systems, breaking content into cold plates, QDs, inner manifolds and rack manifolds. It estimates component counts and ASP changes by tray and rack, then links the resulting content changes to supplier positioning, margins and earnings potential. It also compares forward P/E ranges and its EPS estimates with Bloomberg consensus for the discussed Taiwan suppliers.

Impact & implications
The report says rising cooling content per AI-server platform should favor leading Taiwan suppliers of cold plates, QDs and heat spreaders. AVC is positioned for GPU and ASIC cold-plate upgrades, while Fositek could benefit from ZQD adoption, higher content per rack, gross-margin improvement and share gains.
Risks
- For the heat-spreader supplier, Rubin GPU may see only partial removable-lid adoption during trial volumes, and mass-production content growth may be limited to 4-5x versus the one-piece design.
