What the shared parts are
- Fans — The axial and centrifugal fans mounted in server chassis and rack trays that move air across heatsinks and boards, still needed even in racks that use liquid cooling for the highest-power chips.
- Air-cooled heatsinks & vapor chambers — The finned aluminum or copper heatsinks and vapor chambers that spread and dissipate heat from chips that rely on airflow (4.13) rather than a liquid cold plate.
- Direct-to-chip cold plates — A metal plate with internal microchannels, bonded or clamped directly onto a GPU, CPU, or switch package, that carries coolant across the die to remove heat by conduction rather than airflow.
