    Hi MumboFuze,

    If your brand-new Swift SF16-51’s fan isn’t spinning—even under load—here’s a step-by-step guide to help isolate the issue. This model was released in late 2024 and features Intel Core Ultra processors with Intel Arc graphics, so some quirks are firmware-related.

    🧊 1. BIOS & Firmware Checks

    • BIOS version: Confirm you're running the latest BIOS from Acer’s support site:🔗 Acer Drivers and Manuals
    • Thermal profile: Check if Acer Care Center or Windows power settings are set to “Silent” or “Battery Saver.” These may delay fan activation until temps exceed 70°C.

    🔍 2. Monitor Temps & Fan RPM

    Use tools like:

    • HWMonitor
    • Open Hardware Monitor

    If RPM stays at 0 even when CPU temps rise, it could indicate:

    • EC (Embedded Controller) glitch
    • Fan header issue
    • Firmware misbehavior

    🔄 3. EC & Battery Reset

    These resets often restore fan control:

    EC Reset

    1. Shut down the laptop.
    2. Disconnect the charger.
    3. Hold the power button for 30 seconds.
    4. Reconnect and boot.

    Battery Pinhole Reset

    1. Power off the laptop.
    2. Locate the battery reset pinhole (usually on the bottom panel).
    3. Insert a paperclip and hold for 5–10 seconds.
    4. Wait 1 minute, then reconnect power and boot.

    🧪 4. Stress Test

    Run a CPU stress test using Cinebench or Prime95. If the fan still doesn’t engage past 80°C, it’s likely a hardware or EC firmware fault.
