    Handheld Overheating

    Quick Answer

    Overheating in handheld gaming devices like the Steam Deck, ROG Ally, and Nintendo Switch can cause performance drops, crashes, and potential hardware damage.

    Please note: This guide is provided for informational purposes only. Any steps you choose to follow are at your own discretion and risk. If you're unsure, we recommend booking a professional diagnosis.

    Quick Checks

    Try these fast checks first — they solve most cases.

    1. 1

      Check for blocked vents

      Ensure nothing is covering the intake or exhaust vents.

    2. 2

      Reduce workload

      Lower game settings, resolution, and framerate.

    3. 3

      Move to a cooler environment

      High ambient temperatures contribute to overheating.

    4. 4

      Remove protective case

      Cases can trap heat around the device.

    5. 5

      Reboot the device

      A software glitch may be causing excessive CPU/GPU usage.

    Guided Troubleshooting

    Answer these questions to narrow down the issue.

    Does the device get hot during light tasks like browsing?

    Has the device been dropped recently?

    Are performance drops or shutdowns occurring?

    Possible Causes

    Dust buildup in vents

    Very Common

    Dust insulates components and blocks airflow.

    Demanding games/settings

    Common

    High settings push CPU/GPU to maximum, generating more heat.

    Poor ventilation

    Common

    Playing on soft surfaces or with blocked vents traps heat.

    Dried thermal paste

    Moderate

    Over time thermal paste degrades, reducing heat transfer.

    Failing fan

    Less Common

    A non-functional fan cannot dissipate heat.

    Software bug

    Moderate

    A stuck process can max out CPU usage.

    Self-Fix Instructions

    Safe steps you can try at home.

    Clean vents thoroughly

    1. Power off the device. 2. Use compressed air on all vents. 3. Pay attention to intake vents which collect more dust. 4. Clean regularly every few months.

    Optimise performance settings

    1. Lower resolution and framerate caps. 2. Reduce graphical quality settings. 3. Enable any built-in performance limiter or eco mode. 4. Close unnecessary background apps.

    Improve external cooling

    1. Use the device on a hard flat surface. 2. Consider a cooling stand or external fan accessory. 3. Avoid direct sunlight or hot environments.

    Safety Warnings

    • If the device becomes too hot to hold comfortably, stop using it immediately.
    • Do not attempt to replace thermal paste unless experienced. This voids warranty.
    • Continued use while overheating can cause permanent damage to internal components.

    When troubleshooting isn't enough

    If these steps didn't resolve the issue, a professional diagnosis can identify the root cause.
