Start by checking for the fuse, then use a test light to ensure power is reaching the wiring for the fan. There is no reason why the fan stops suddenly after a bootup. Motherboards /logic boards are specifically designed to vent the hot air and keep the dice or chip cool. Why is my car not heating up? The fan is hooked up to the radiator through a network of various wires that can become prone to corrosion over time, and the radiator can overheat if the fan isn't providing adequate air circulation when at a stop or standstill if it gets hot enough. Usually, if the CPU fan is broken, it will stop running. With a closed thermostat, your engine will immediately start to overheat. My Computer Fan is not working.

If the sensor isn't working, your fan won't come on because it won't know that the temperature is hot enough to require activation, which can frequently lead to overheating. Thermostatically controlled motors do not work the fan until the engine coolant rises above normal operating temperature, and then switch off when it has cooled down again. Are the fan blades turning? When it does happen, you're left with a miserably underpowered heat or AC system.
