Context Before
Our VR NVL72 Component BoM and Power Budget Model ↗ has provides the $ content breakdown of high end CCL and PCB content for VR NVL72 vs GB200/GB300.
Compute Tray: Thermal
Evidence
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 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. Each of the modules within the compute tray will have a cold plate module attached. Each cold plate module connects to the internal manifolds via MQD (a smaller form factor quick disconnect specification standard by Nvidia for compact area application within the compute tray).

}⑥ Human Review
請在 Properties 逐項確認：
- 原文 → Atomic Claim 是否忠實
- Atomic Claim → Semantic Frame 是否忠實
- Canonical Entity mapping 是否正確
- Epistemic mode 是否保留原文語氣
