Context Before
The midplane and the internal manifolds are shipped together as a module. The mechanical design of this module is shown in the picture above. These highlighted mechanical parts acts as a loading mechanism for the modules. These loading mechanisms ensure the modules are well connected to the Paladin connectors and the MQD by applying some force to the modules locking them in place.

Evidence
the statement that Vera Rubin can operate with 45C inlet temperatures, potentially avoiding mechanical compressor-based chillers, was viewed as a major surprise for much of the cooling supplier ecosystem
Context After
Vera Rubin will be able to operate at a 45C inlet temperature, but Blackwell is already capable of operating with inlet water temperatures above 40C (see for example Supermicro’s DLC-2 system). Major system vendors such as Lenovo and HPE have also been discussing 100% liquid-cooled architectures operating at 45C since early 2025. In 2024, HPE announced an industrial cooling system based on full liquid cooling, and similar approaches have long been used before in HPC. Lenovo discussed the next generation of its Neptune liquid solution at the 2025 OCP Summit, which is fully liquid-cooled and also uses 45C water.
② Atomic Claim
Vera Rubin 可在 45°C inlet temperature 運作、可能不需要 mechanical compressor-based chillers 的說法，對許多 cooling supplier ecosystem 參與者而言是一大意外。
