NOVA-DC S2
A dual-socket server mainboard, taken apart one layer at a time. Scroll to open it up.
440 × 300 mm board, 16 layers, 34 modeled parts.
Thirty-four parts, one stack
Backplates sit under the board. Sockets, memory slots and connectors rise first, then CPUs, load plates, thermal paste, heatsinks and screws.
Two processors
Each LGA4677 socket takes a 56-core CPU under a nickel heat spreader. A load plate and two levers clamp it onto 4,677 contacts.
Heat leaves through the fins
A copper plate meets the CPU through a thin layer of paste. Four heat pipes carry the heat into 33 aluminium fins, and chassis fans push air straight through.
Twelve DIMMs, parallel to airflow
Six registered DDR5 modules flank each CPU. Running along the airflow lets cool air pass over every module.
Power stays close to the CPU
Seven power stages and fourteen chokes per socket, backed by polymer capacitors and two 8-pin 12 V inputs at the rear.
Connectivity and management
An OCP NIC 3.0 card adds dual 25 GbE. Riser slots, MCIO ports and a BMC with its own flash round out the I/O.
Put back together
Same board, same parts, assembled. Open the viewer to take it apart yourself.
