Context Before

VR NVL72 takes liquid cooling to the next level. The VR NVL72 compute tray is 100% liquid cooled, whereas GB200 and GB300 compute trays adopt a hybrid of 85% liquid cooling and 15% air cooling. As a result of this, fans are removed from the compute tray and

Evidence

the cold plate coverage increases to remove heat from the front half of the chassis.

Context After

An internal manifold will be placed in the middle of the chassis to distribute inlet coolant to the various modules and to collect the outlet coolant.

② Atomic Claim

cold plate coverage 增加，以移除 chassis 前半部的熱。
