Historically, cooling fans run at 100%, even when less airflow is needed, constantly turning on and off as the engine temperature changes. This reaction-based temperature control system causes constant amperage spikes, excessive noise, and premature wear. The Derale PWM fan controller continuously monitors your engine's temperature, therefore controlling the temperature and increasing the vehicle's cooling efficiency, while reducing the amps used to do so. Here's how it works. The controller monitors your engine temperature via the side of the radiator, therefore providing a more accurate reading for your cooling system. Using Soft Start Technology, fans ramp up slowly which eliminates harmful AMP spikes. Our new control will keep your fans running for an additional 20 seconds after you turn your vehicle off. The unit will continuously monitor your engine's temperature and operate the fans at the optimum fan rate as needed between 1 to 100%. The net result is that the electric fans often only run between 40-60% to keep your engine cool. Additional benefits include reduced fan speeds, which means reduced fan noise, which tends to compete with that sweet sound of your engine! This multi-fan controller has a built-in A\/C Over-ride circuit and is designed to control as many 12-volt brushed electric fans as desired, up to 70 Amps combined. Even better, installation and calibration are a snap. It simply wires in-between your vehicle's battery and electric fans.\n\u003cbr\u003e\n\u003cbr\u003e\u003ch5\u003e\u003cspan style=\"color: #e42626\"\u003eFeatures\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eReduced Fan Noise\u003c\/li\u003e\n\u003cli\u003eSoft Start Technology\u003c\/li\u003e\n\u003cli\u003eBlack Finned, 6061 Aluminum Housing\u003c\/li\u003e\n\u003cli\u003eAir Conditioning Override Circuit Built-In\u003c\/li\u003e\n\u003cli\u003eIncludes Automatic Resetting Circuit Breaker\u003c\/li\u003e\n\u003cli\u003eControls Multiple Electric Fans Up To 70amp Capacity\u003c\/li\u003e\n\u003cli\u003e20-Second Cooldown Timer When The Vehicle Is Turned Off\u003c\/li\u003e\n\u003cli\u003ePulse Width Modulation Controls Fan(S) Speed From 0-100%\u003c\/li\u003e\n\u003cli\u003eConstantly Adjusts Fans Speed To Maintain The Desired Temperature\u003c\/li\u003e\n\u003cli\u003eBuilt-In Protections: Short Circuit, Over Amperage, Low Voltage, High Voltage, Reverse Polarity, Over Temperature \u0026amp; Anti Flyback\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003eSpecifications\u003cbr\u003eAmp Rating: 70 Amp\n\u003cbr\u003eWidth: 3\"\n\u003cbr\u003eLength: 5-13\/16\"\n\u003cbr\u003eDepth: 1-5\/8\"\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Derale Performance","offers":[{"title":"Default Title","offer_id":45505079541783,"sku":"DER16797","price":343.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9387\/6759\/files\/16797_Derale-Performance_022426_1.jpg?v=1793219416","url":"https:\/\/ce1fdc-a9.myshopify.com\/products\/xdp-derale-16797-pwm-fan-controller-70-amp-surface-mount-sender","provider":"Honey Badger Motor Sports","version":"1.0","type":"link"}
