Thermal Paste

A conductive material applied between the CPU/GPU and the heat sink to improve heat transfer.

Radiator (in liquid cooling)

A component that dissipates heat from the liquid coolant via fins and fans.

Pump (in liquid cooling)

Circulates coolant through the system.

Coolant (in liquid cooling)

Liquid that absorbs heat from components and carries it to the radiator.

Case Ventilation

Intake and exhaust vents/fans in the computer case to maintain airflow.

TYPES

1. Air Cooling

   • Uses heat sinks and fans to cool components.

   • Most common and cost-effective.

   • Examples: Stock CPU coolers, aftermarket air coolers like Noctua NH-D15.

2. Liquid Cooling (Water Cooling)

   • Uses liquid coolant circulated through tubes and radiators.

   • More efficient heat dissipation, quieter operation.

   • Two types:

     • Closed-loop (AIO - All In One): Pre-filled, maintenance-free units.

     • Custom loop: Fully customizable but requires maintenance and expertise.

3. Passive Cooling

   • No fans, relies on large heat sinks and natural convection.

   • Usually found in low-power or silent systems.

4. Hybrid Cooling

   • Combines air and liquid cooling for optimized performance.

WHAT COOLING SYSTEM SHOULD I USE?

• For Typical Users/Gamers:
  A good-quality air cooler or AIO liquid cooler is usually sufficient. Air coolers like the Cooler Master Hyper 212 or Noctua NH-U12S are reliable and affordable.
