Buying Guide

Match socket and form factor

Confirm compatibility with your CPU socket or server chassis (e.g., AMD SP3, G34, 2U/low-profile) to ensure fit and mounting alignment

Choose active vs passive appropriately

Passive extruded aluminum sinks suit noise-sensitive or well-ventilated systems, while blower-style or heatpipe solutions add airflow and active cooling for higher TDPs

Evaluate thermal design features

Look for features like heatpipes, fin density (27-fin examples), and large surface area that improve heat transfer for sustained loads

Check fan/blower specs and control

For active coolers, prefer PWM-capable blowers or fans (e.g., 80x80x15 mm PWM) to balance noise and cooling across workloads

Prioritize build material and size

Aluminum extrusion sinks provide lightweight, corrosion-resistant performance; verify overall dimensions (length, width, height) to avoid clearance issues
