Context Before

VR NVL72 takes liquid cooling to the next level. The VR NVL72 compute tray is 100% liquid cooled, whereas

Evidence

GB200 and GB300 compute trays adopt a hybrid of 85% liquid cooling and 15% air cooling.

Context After

As a result of this, fans are removed from the compute tray and the cold plate coverage increases to remove heat from the front half of the chassis. 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

GB200 與 GB300 compute trays 採用 85% liquid cooling、15% air cooling 的 hybrid cooling。
