eTronix RC Motor Cooling Fans & Heatsinks

Keep motor temps in check with our Fans and Heatsinks for RC Motors. Whether you run 1/10 touring, buggies or bashers, we stock 25mm, 30mm, 35mm and 40mm fans plus precision aluminium heatsinks from Hobbywing, Hudy, RC Overhaul, Fastrax and Centro. Choose receiver-powered 5–6V units or HV 7.4V fans for direct 2S use—just ensure your BEC has spare current. Heatsinks cover popular 540/550 and 36–42mm can sizes, with clamp-on, strap and combo fan/heatsink assemblies for maximum airflow. Fitment tips: check clearance to chassis and top decks, orient the fan to blow onto the can, route wires clear of gears, and match the connector (JST or receiver). Consider shrouds or ducts to focus cooling, and use supplied thermal pads or paste for best heat transfer. Keep debris out—a simple mesh guard prolongs fan life. We carry large stocks for fast dispatch, backed by our friendly, knowledgeable team ready to help you choose the right size, voltage and mounting. UK delivery options include next day on eligible items, so you can get back on track with cooler, more consistent performance. Don’t forget spares like replacement fan blades, screws and mounting bands.
