Heatsinks & Cooling Fans
12 products
Effective heat management is essential for the reliable and long-lasting operation of electronic circuits. Heatsinks and cooling fans keep temperature-sensitive components like processors, power transistors, voltage regulators, and LED drivers within safe limits. This category includes passive aluminum heatsinks, active heatsink-fan combos, DC cooling fans, and the necessary thermal paste and thermal pads for proper mounting.
Heatsink Types
Passive heatsinks, typically made from aluminum or copper alloys, use fin designs to increase surface area and dissipate heat through natural convection. Common styles include pin types for TO-220/TO-247 packages, star-shaped for LED stars, and large block heatsinks. Active heatsinks combine a passive block with an integrated fan, delivering more effective cooling for high-power applications.
Fan Selection Criteria
When choosing a cooling fan, consider rated voltage (12V, 24V, 5V), size (40mm, 60mm, 80mm, 120mm, etc.), airflow (CFM), static pressure (mmH₂O), noise level (dBA), and bearing type (sleeve, ball, hydraulic). In confined spaces, high-static-pressure fans are better; open systems benefit from high-airflow models. PWM-controlled fans allow dynamic speed adjustment, optimizing both noise and power consumption.
Compare thermal resistance (Θ), available mounting area, and power consumption to select the most efficient solution for your project.
