Cooling system for a single Nvidia Blackwell Ultra NVL72 rack costs a staggering $50,000 — set to increase to $56,000 with next-generation NVL144 racks

Morgan Stanley estimates that the cooling cost per rack will rise from $49,860 for Nvidia’s GN300 NVL72 to $55,710 for the Vera Rubin NVL144 due to hotter Vera CPUs and Rubin GPUs that require pricier $400 cold plates and more advanced liquid cooling systems.

Cooler Master debuts new 3D Heatpipe tech in new coolers — Hyper 212 3DHP promises reduced thermals and improved efficiency

Cooler Master is updating its iconic lineup of Hyper 212 coolers with its proprietary 3D Heatpipe tech. Hyper 212 3DHP, therefore, has two trident-like heatpipes running through its finstack that dissipate heat more evenly while costing the same. They will come in two flavors: Black and ARGB, and will be backed with 5-year warranties.
