Where is the air shroud located on the PCIe tray?

The air shroud on the PCIe tray in Supermicro systems like the SYS-421GE-TNHR2-LCC is positioned to optimize airflow or assist liquid cooling efficiency in hybrid setups. Per Supermicro’s design (e.g., SYS-420GP-TNAR), the shroud is located on the top/center of the PCIe tray, covering the cards to direct cooling effectively across components. This central placement ensures even distribution, critical in DLC systems where air may still cool non-liquid-cooled parts. Options B and D (right/left) are less practical for uniform coverage, and A (bottom) contradicts standard shroud placement above components. Supermicro’s DLC expertise integrates air shrouds strategically, making C the verified location.References:Supermicro PCIe tray diagrams, DLC solution design principles.
