Hi. Do you own a infrared thermometer? This is a great tool to have when diagnosing heating issues and testing ECT sensor accuracy. Just because a part is new doesn't mean it can not be defective. So you don't chase your tail I recommend testing. The fan clutch will free spin if the clutch is defective or the thermo coil does not sense enough heat from the radiator. I think your truck has a circulation problem. There are multiple reasons for this issue. For example: defective ECT sensor, low coolant, leak, defective radiator cap, compression in coolant system, clog or restriction inside engine or radiator from human error (shop rag left inside from recent repair), a collapsed hose or failed rusty coolant, defective water pump or thermostat, improperly installed thermostat, or defective fan clutch. Please write back if there is anything else. Good Luck.
