Nintendo Switch Overheating

Low-quality or third-party accessories may not deliver the proper power or cooling required for optimal performance. For example, some third-party external cooling fans can sometimes cause the Switch to overheat because they divert the airflow to the wrong location.

• Remove any connected accessories, including external fans, hard drives, and charging accessories. Then, check your Switch and see if the issue persists.
• Test your accessories to see if the issue has been resolved. If your console is no longer overheating, try plugging in your accessories one at a time to see if the issue happens with one particular accessory.

One of the few other steps before opening your Switch is resolving potential software issues. Thankfully, there are several different ways to do this.

In most instances, a software update can resolve issues affecting how your Switch's hardware functions.

1. Power off your Switch.
2. Press and Hold the Volume Up, Volume Down, and the Powerbuttons simultaneously. This will boot your system into Maintenance Mode.
3. Select the Update System option.
4. Once your Switch has finished updating, Restart your Switch

If a software update cannot resolve your issue, you can initialize your Switch through Maintenance Mode.

1. Power off your Switch.
2. Press and Hold the Volume Up, Volume Down, and the Powerbuttons simultaneously. This will boot your system into maintenance mode.
3. Once your system has booted into Maintenance Mode, choose Initialize Console Without Deleting Save Data.
4. Select Next, and Initialize Console Without Deleting Save Data.

While your vents may be clean and free of dust, you could have an issue with dust and debris having built up in your Switch's internal components.

1. Please turn off the console and unplug it from the power source.
2. To access the internal cooling fan, use iFixit's Nintendo Switch Fan Replacement guide.
3. Use compressed air, or other product, and a soft brush to gently clean the vents, fan, and heat sink.
4. Be sure that the fan is clean and is spinning freely.

If you frequently run intense graphics games, the issue may be caused by an overused system. Cooling periods should be taken to allow the console to cool down before further use.

• If you've been gaming for an extended period, around 5 to 6 hours without breaks, consider taking breaks to allow the console to cool down.
• Please turn off the console during breaks to let it cool more efficiently. Ideally, you should wait an hour for it to cool down.

If you are still experiencing issues with your console, consider opening your Switch to see if there is any potential damage internally.

• Check the console's fan for damage or warping. Ensure your Nintendo Switch's cooling fan is spinning correctly in its housing and is connected to and receiving power from the Switch's Motherboard. Replace the malfunctioning fan with a new one if needed.
• Look at your Switch's heatsink for dust build-up. Locate your Switch's Heat Sink, and ensure the heatsink is clean and debris-free. If you notice any damage, try replacing it with a new one.
• Replace the thermal compound underneath the heatsink. Most thermal compounds become less effective over time, especially when used in a system with heavy use. Consider changing out your thermal compound if you have had your system for an extended period.
• Perform a thorough visual inspection of the console's motherboard for any signs of burns or damaged components. If you observe any visible damage, such as burns or components that appear to be physically damaged, the board must be replaced with a new one.
