Why Is My Nintendo Switch Fan So Loud? (14 Reasons & Fixes)

If your Nintendo Switch fan suddenly sounds like a jet engine, you might be worried.

Why is my Nintendo Switch fan so loud?

A Nintendo Switch fan is so loud because of factors like dust accumulation, overheating, software glitches, aging hardware, and physical obstructions. The issue might also be poor ventilation, damaged fan blades, product defects, third-party docks, incorrect settings, malware, or background apps.

In this guide, you’ll learn 14 reasons why your Nintendo Switch fan might be so loud and what to do about it.

The Reason

Dust accumulation is a common issue affecting electronics.

Dust particles can create an insulating layer over the hardware components, including the cooling fan.

This makes it difficult for the fan to circulate air, causing it to work harder and subsequently produce a louder noise.

The Fix

  1. Turn off your Nintendo Switch and unplug it from any power sources.
  2. Use a compressed air duster and blow air into the fan grills to remove dust.
  3. Perform this cleaning at least every 2-3 months to maintain optimal fan performance.

2. Overheating

The Reason

Your Nintendo Switch can overheat due to long gaming sessions or resource-intensive games.

Overheating makes the fan speed up in an attempt to cool down the internal components, leading to a loud fan noise.

The Fix

  1. Place your Nintendo Switch on a flat, hard surface to facilitate better heat dissipation.
  2. Ensure the room temperature is cool.
  3. Take breaks every hour to allow the device to cool down.

3. Software Glitches

The Reason

Sometimes, software glitches stemming from a system update or an in-game issue can cause the fan to behave abnormally.

These glitches might make your fan noisier than usual.

The Fix

  1. Update your Nintendo Switch to the latest firmware.
  2. Reboot your device to clear any temporary software glitches.
  3. If the problem persists, try uninstalling and reinstalling the game causing the issue.

4. Aging Hardware

The Reason

Like all electronic devices, the Nintendo Switch undergoes wear and tear over time

An older fan motor might not be as efficient as it used to be, resulting in louder operation.

The Fix

  1. Check the warranty status of your Nintendo Switch.
  2. If out of warranty, consult a professional to assess if a fan replacement is necessary.

5. Physical Obstructions

The Reason

Foreign objects like small pieces of paper, hair, or even crumbs can sometimes get into the fan area.

Obstructions can cause it to make strange, loud noises when spinning.

The Fix

  1. Turn off and unplug your device.
  2. Inspect the fan area for obstructions and remove any carefully with tweezers.

6. Poor Ventilation

The Reason

Poor ventilation can suffocate your Switch, causing it to heat up quickly.

This forces the fan to go into overdrive to compensate for the lack of air circulation.

The Fix

  1. Ensure the Nintendo Switch is placed in a well-ventilated area.
  2. Keep it away from other heat-generating devices to avoid additional heat build-up.

7. Damaged Fan Blades

The Reason

Cracked or damaged fan blades can disrupt the balance of the fan’s spin, causing it to wobble and generate more noise.

The Fix

  1. Check for visible signs of damage to the fan blades.
  2. If found, consult professionals for a fan replacement.

8. Manufacturing Defects

The Reason

Sometimes the fan may have manufacturing defects that can cause loud noises.

The Fix

  1. If under warranty, take your Nintendo Switch to an official service center for a check-up and potential replacement.
  2. Avoid trying to repair it yourself, as this could void the warranty.

9. Third-Party Docking Stations

The Reason

Not all third-party docking stations meet Nintendo’s quality standards.

Unfortunately, some may cause your Switch to overheat, leading to a loud fan.

The Fix

  1. Stick to using official Nintendo docking stations.
  2. If you must use a third-party dock, ensure it has good reviews and meets quality standards.

10. Incorrect Settings

The Reason

Certain system settings like screen brightness or running multiple apps can contribute to quick heating.

In a digital chain of events, this can make your Switch fan work harder.

The Fix

  1. Navigate to system settings and adjust screen brightness and other performance-related settings.
  2. Close unnecessary apps running in the background.

11. Malware

The Reason

Although it’s uncommon, malware infections can cause your Nintendo Switch system to use more resources than necessary.

Malware infections can cause the game system to heat up and the fan to become loud.

The Fix

  1. Perform a system reset to clear any malware. Make sure to back up your data first.
  2. If the issue persists, consult professionals for a deeper analysis.

12. Poor Thermal Paste Application

The Reason

Thermal paste is used to facilitate better heat transfer between the CPU and the heat sink.

If the thermal paste is not applied correctly during manufacturing or has dried out over time, it may result in inefficient cooling and louder fan noise.

The Fix

  1. Check your warranty status, as opening your Nintendo Switch yourself can void it.
  2. If your device is out of warranty, you may choose to apply new thermal paste yourself or have a professional do it.

13. Multiple Background Applications

The Reason

Sometimes running multiple applications in the background while gaming can consume more system resources.

This can cause the fan to work harder and make more noise.

The Fix

  1. Navigate to your Switch’s home screen and close any unnecessary applications that are running in the background.
  2. Try to maintain a practice of running only the applications you need during gaming sessions.

14. Fan Bearing Issues

The Reason

The bearings in the fan may deteriorate or get misaligned over time, causing additional friction and noise when the fan spins.

The Fix

  1. Listen closely to the fan; if it’s making grinding noises, the bearings might be the issue.
  2. If your device is still under warranty, seek professional repair. If not, you might consider replacing the fan yourself, although this requires some technical skill.

Can I Fix a Loud Nintendo Switch Fan By Myself?


Many of the reasons leading to a loud Nintendo Switch fan can be addressed with some basic troubleshooting.

This is what you need to do:

  1. Regular Cleaning — Ensure that your system is free of dust and debris. Regular cleaning can prevent overheating caused by dust accumulation.
  2. System Updates — Always keep your Switch updated to the latest software version. This can solve fan issues related to software glitches.
  3. Optimal Settings — Navigate through your system settings to ensure they’re optimized for performance and cooling.
  4. Use Official Accessories — Stick to official Nintendo docks and avoid third-party alternatives that may not meet the necessary standards.

However, it’s essential to be cautious. If you’re not confident in your abilities or the fixes seem too technical, it’s better to consult a professional.

When to Call a Professional

There are certain instances where you’d be better off seeking professional help.

Some of these times include:

  1. Damaged Fan Blades — If the fan blades appear damaged or broken, it’s a complex issue that requires expert intervention.
  2. Thermal Paste Issues — If you suspect that the thermal paste between the CPU and heatsink is worn out or wasn’t applied properly, a professional should address it.
  3. Fan Bearing Problems — If the fan makes grinding noises indicative of bearing issues, a professional check is in order.
  4. Potential Malware — In rare cases, if you think your system might be compromised by malware and a simple system reset doesn’t solve it, seek expert advice.

Remember, if your Nintendo Switch is still under warranty, always opt for official Nintendo service centers.

When to Replace My Game System?

Replacing your Nintendo Switch should be the last resort.

Here’s when you might consider it:

  1. Recurring Issues — If the fan noise problem persists even after multiple professional repairs, it might be more cost-effective to get a new system.
  2. Outdated Hardware — The lifecycle of gaming consoles can be several years, but if your system is significantly outdated, newer game titles might overstrain it, causing louder fan noises and other issues.
  3. Cost of Repairs — If the cost of repeated repairs approaches or exceeds the price of a new unit, it’s economically wiser to invest in a new system.
  4. Performance Lags — If you notice significant performance issues, slower load times, or frequent crashes in conjunction with fan noise, it could be a sign that your system is reaching the end of its lifecycle.

If you’re going to replace your Nintendo Switch, personally, I’d go for the Nintendo Switch™ Mario Kart™ 8 Deluxe Bundle.
