Liquid‑Cooled NVIDIA Servers Showcased at ASRock Rack OCP 2026 Booth
At the OCP Global Summit 2026 in San Jose, ASRock Rack displayed a range of liquid‑cooled NVIDIA systems, from the full NVL72 rack to HGX Rubin NVL8 servers and the Spectrum‑X SN6600‑LD switch. The solutions use direct‑to‑chip cooling to cut power draw while delivering multi‑petaflop performance.
Key points
- 48RU XGMRACK‑VR/NVL72 rack packs 36 Vera CPUs and 72 Rubin GPUs with 20.7 TB HBM4.
- 2U‑16X‑GNR2/DLC Rubin HGX server hosts 8 GPUs, fully liquid‑cooled, delivering 400 PFLOPS sparse compute.
- Liquid‑cooled NVIDIA Spectrum‑X SN6600‑LD switch and RTX PRO 4500 Blackwell servers were also on display.
What it means for Iran
These new liquid‑cooled servers could offer high performance with lower power use for Iranian datacenters.
- Availability: Because the hardware reaches Iran via unofficial channels (Dubai, Turkey, China), lead times are likely several months longer than the vendor’s stated delivery.
- Support & licensing: No official NVIDIA or Intel warranty/support exists in Iran; software licences (e.g., NVIDIA AI Enterprise) may not be activatable legally.
- Cost & power: Direct‑to‑chip liquid cooling reduces electricity consumption, which can lower generator and UPS expenses amid Iran’s scheduled power cuts.
Recommendation: Verify estimated lead times, additional licensing costs, and the feasibility of liquid‑to‑chip cooling with the reseller before committing to purchase.
