Aluminium 380 and 390 Motor Heat Sink with 5V Cooling Fan for 1/16 and 1/18 Scale RC Car - Red Anodised Active Forced-Air Motor Cooling with JST Connector, 7000 RPM Fan
The Aluminum 380 and 390 Motor Heat Sink with 5V Cooling Fan is a purpose-sized active motor cooling assembly designed specifically for 380 and 390 class brushed motors used in 1/16 and 1/18 scale RC cars, providing combined conductive aluminium alloy heat sink and forced-air fan cooling to prevent motor overheating during sustained high-load and full-throttle driving in the compact chassis and motor bay dimensions of small-scale RC vehicles. The 26mm inside diameter is precision-matched to the 380 and 390 motor can dimensions, ensuring a secure, flush contact fit between the heat sink body and the motor can surface for effective metal-to-metal conductive heat transfer without the air gaps that reduce thermal efficiency in loosely fitted heat sink assemblies. The DC 5V 0.12A fan operates at 7000 RPM at rated voltage, providing active forced-air flow across the heat sink fin structure at a fan current draw low enough for direct powering from the RC receiver spare port or ESC BEC output without exceeding the current budget of standard small-scale RC receiver power rails.
The JST connector on the fan power lead provides a standardised, tool-free power connection to compatible JST-equipped RC receivers, ESC BEC outputs, and auxiliary power taps common across 1/16 and 1/18 scale RC car electronics, making the installation process straightforward without requiring soldering or connector replacement in most standard small-scale RC vehicle builds. The red anodised aluminium finish provides a visual upgrade alongside the thermal management function, and the 30 x 30 x 45mm overall assembly dimensions keep the heat sink and fan footprint compact for the restricted motor bay space available in 1/16 and 1/18 scale chassis. At approximately 20 grams, the assembly adds minimal weight to the small-scale RC vehicle while delivering a meaningful reduction in sustained motor operating temperature that directly extends motor service life and maintains consistent performance across extended run sessions where motor heat accumulation would otherwise degrade power output and risk permanent winding or magnet damage.
