Heatsinks

Match the heatsink to your component's socket or mounting pattern, check TDP rating to ensure it can dissipate your component's heat, and confirm physical clearance for RAM, case height, and nearby connectors

Common types are passive (no fan) for low-power or silent builds, active air coolers with fans for general-purpose and high-TDP CPUs, and heatsinks with heat pipes or larger fin stacks for higher cooling capacity; choose based on thermal needs, noise tolerance, and space constraints

Very important: check cooler height versus case clearance, backplate or bracket compatibility with your motherboard socket, and whether the cooler obstructs RAM slots or PCIe slots before purchasing

Budget heatsinks under about (price varies) typically handle moderate TDPs and may be louder; higher-end models offer better heat dissipation, quieter operation, and more durable materials, with prices increasing as design complexity and performance rise

Regularly clean dust from fins and fans, check that mounting hardware remains secure, and replace thermal interface material when removing or re-seating the heatsink to maintain thermal transfer

Yes—fan noise varies by fan size and RPM; larger fans can move more air at lower RPMs for quieter operation, and using PWM-controlled fans or a fan curve in BIOS/software can reduce noise under light loads

Compare TDP rating or thermal resistance, dimensions (height, width, depth), weight, fan size and RPM range, mounting compatibility, and whether heat pipes or vapor chambers are used for heat transfer
