Where is the cooling vent on the macbook pro

There are three codes, all starting with "PPF," related to the cooling fan. If you get one of the results that indicates there may be an issue with your fan, it's time to contact Apple Support or visit your nearest Genius Bar for a repair. If your Mac is clean and grime-free and you are keeping your apps and tabs in check and the fan is still spinning frequently and loudly, then try resetting the System Management Controller SMC.

The SMC is responsible for controlling low-level functions on your Mac including "thermal management," aka the cooling fan. Follow Apple's instructions for resetting the SMC.

While processors CPUs and GPUs are the primary heat generating components within a laptop, essentially all electrical components generate some heat. The computer memory RAM and storage hard drive modules also generate heat. Apple laptops, as with most laptops, use a built-in cooling system to remove internal heat.

These cooling systems consists of the following components that will be reviewed in greater detail in the subsequent sections: 1 an external aluminum enclosure heat sink, and 2 an air cooling system that includes one or more processor heat sink, heat pipe, heat radiator fan, cool air intake vent and hot air exhaust vent.

Aluminum Enclosure The first production Mac laptop with a metal enclosure was released in , and by all Mac laptops began to use an anodized aluminum metal enclosure. This helps create a structure that is light, strong and rigid, as well as creating a durable and beautifully finished surface. The aluminum enclosure also acts as a heat sink, absorbing heat from internal heat generating components through direct physical contact conduction , heat waves radiation and hot air convection. For the aluminum enclosure to function as an effective heat sink that absorbs heat from internal heat generating components and then expels it into the surround environment, the enclosure needs to be uncovered and as open as possible to the surrounding environment.

For the most effective cooling, then the enclosure should be exposed to cooling airflow or another external heat sink to pull heat away from the laptop. This means that running the laptop with the screen open will increase heat transfer and allow for greater cooling, so if you prefer running with the screen closed in clamshell mode, then supplemental cooling becomes essential. This also means that while laptop covers and cases may serve their purpose in decorating and protecting surfaces, those are typically made of insulating materials such as plastic and wood that will negatively impact cooling by insulating the aluminum enclosure and preventing heat from escaping.

Each particular setup has its advantages and disadvantages, so a user decides what best serves their needs. Air Cooling All recent Mac laptop models with a built-in air cooling system include one or more processor heat sinks, heat pipes, heat radiators, fans, cool air intake vents and hot air exhaust vents. The processors, heat sink, pipe and radiator are typically the areas on a laptop with the highest temperatures.

Use your device on a hard, flat surface like a table or desk for optimal temperature control. If you use your device on a soft surface like a couch, pillow, bed, or your lap, its fans might run more. If the fans in your device run fast even when it isn't experiencing heavy usage and is properly ventilated, follow the steps for your device:.

About fans and fan noise in your Apple product Learn how your Apple product monitors internal temperatures and uses fans to cool critical components. About fan noise If your device's processor is working on intensive tasks—such as compressing HD video, playing a graphics-heavy game, or indexing the hard drive with Spotlight after you migrate data—the fans run faster to provide additional airflow. Make sure the vents on your Apple product aren't blocked Some Apple products have vents that let fans bring in cool air and expel hot air.

Check for unexpected heavy fan use If the fans in your device run fast even when it isn't experiencing heavy usage and is properly ventilated, follow the steps for your device: On an Intel-based Mac : Reset the System Management Controller SMC On a Mac computer with Apple silicon : Close and open the lid on your notebook, or restart your computer.
