OCP CE - ACF Cold Plate Sub-Project Call (Jan 14, 2026)

Why It Matters

Accelerating the finalization of cold‑plate specifications and interoperability testing ensures rapid deployment of efficient cooling solutions across OCP‑compliant data centers, directly impacting performance and cost competitiveness.

Key Takeaways

• Regional summit presentations due by February 9, submit content promptly.
• PG25 base spec submitted; guidelines near final approval this month.
• Compatibility data for polyamide 11/12 expected within six weeks.
• Cold‑plate interoperability testing scheduled; vendors invited to join.
• PBMC coupling design targets 1RU form factor with 5 mm misalignment tolerance.

Summary

The OCP CE ACF Cold Plate sub‑project call opened with logistical housekeeping and a reminder that the regional summit’s call for presentations closes on February 9. Participants were urged to submit abstracts and slide decks early to ensure representation of their workstreams at the upcoming event.

Key updates included the submission of the PG25 base specification and the near‑finalization of its accompanying guidelines, which are slated for approval later this month. The group is awaiting material‑compatibility results for polyamide 11 and 12, expected within the next four to six weeks, to potentially expand the list of approved wetted materials. Cold‑plate workstreams reported progress on validation, under‑flow testing, and interoperability testing, inviting vendors to join scheduled sessions on Jan 21 and Feb 4.

Notable remarks highlighted the urgency of finalizing documentation: “We are moving along with the submission process” and “the guidelines are at the final stage of approval.” The PBMC (pivoting blade coupling) design was showcased, emphasizing a 1RU footprint, 5 mm radial misalignment tolerance, and hose‑routing independence—features aimed at broad rack compatibility.

The implications are clear: timely submission of specifications and active participation in testing are critical to maintaining momentum in OCP’s cold‑plate ecosystem. Delays could stall standard adoption, while coordinated vendor involvement will accelerate interoperability and market readiness for next‑generation data‑center cooling solutions.
