This is a new replacement cooling fan compatible with the SUNON model KD2404PQB1. It's a small 4cm by 4cm (40mm) DC brushless fan that operates on 24 volts and uses 2.00 watts of power. If the fan in your electronics, computer component, or other device has stopped working and matches this model number, this is the part you need. **Very Important:** Cooling fans can have different wiring sequences even if they look similar. Before ordering, please check the wiring of your old fan and compare it, or contact the seller with photos of your original fan's connector to ensure this replacement will work correctly in your specific application.
