Check socket support
Confirm that the specific cooler package supports the processor socket and includes the mounting hardware required. Consult the manufacturer’s current compatibility list before completing a build.

Fan size and heatpipe count help distinguish models, but neither spec alone guarantees a better match for every PC. Compare the full cooler design, CPU needs and chassis airflow before selecting.
Match the cooler to your build priorities
Choose Noctua NH-D15 G2 CPU Cooler for a premium roomy build, or Thermalright Peerless Assassin 120 SE Black CPU Cooler for a shorter dual tower. Consider single-tower and other seven-heatpipe alternatives when layout takes priority.
