4U Active Heat Sink for LGA4189
The Supermicro SNK-P0081AP4 is a 4U active heat sink built for socket LGA4189 platforms. It supports uni-processor and dual-processor configurations using 3rd Gen Intel Xeon Scalable processors with a thermal design power up to 270 Watts. The unit is validated by Supermicro for X12 generation workstations and gaming systems.
Sustained Load Behaviour
A 92 mm PWM fan spins at 5000 RPM to move air continuously across the fin stack, keeping acoustic output at 43 dB(A) at rated speed. The 12.0 VDC motor is rated for 3000000 hours MTBF, indicating the cooler is engineered for constant operation in server environments rather than short bursts. Speed control adjusts airflow to match thermal demand without manual intervention.
LGA4189 Platform Constraints
The cooler mounts exclusively to the FCLGA4189 socket used by 3rd Gen Intel Xeon Scalable CPUs, so it cannot be used on earlier or later socket generations. Its 4U form factor fits standard 4U rack chassis but will not clear lower-profile enclosures. The 270 W TDP ceiling defines the maximum processor heat load the assembly is validated to dissipate.

Questions about this item
How loud is the 5000 RPM fan when the heat sink runs continuously at full speed?
The 92 mm PWM fan produces 43 dB(A) at its rated 5000 RPM, so sustained full-load operation stays at that acoustic level.
Which motherboard mounting hardware must already be present for this LGA4189 heat sink to install?
The cooler uses the standard LGA4189 square ILM retention frame; the motherboard must provide that socket mounting pattern.
Will this 4U active cooler fit alongside existing DIMMs and PCIe cards in a dual-processor X12 server?
Designed for 4U chassis with uni- or dual-processor X12 boards, it clears standard DIMM slots and low-profile PCIe risers in that form factor.
