Predator sense isn't a good solution. only auto, max and manual states can be chosen.
Manual just setting current max speed which is not corresponds to the temperature of the CPU. Also there is no solution in BIOS to decrease CPU performance as on
PHN16-71. Lenovo Legion Pro5 with same i7-14650hx provides all user needed bios configs for thin configuring.

    Hi Dimmetrius

    To reduce CPU temps and fan spikes on the PHN16-72, try these steps:

    🔧 Disable Processor Performance Boost: Use Regedit to unhide the "Processor Performance Boost Mode" setting:

    • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7
    • Change Attributes from 1 to 2 This reveals the boost option in advanced power settings, allowing you to set it to Disabled.

    ⚙️ Choose the right power plans:

    • Set Balanced Mode in PredatorSense
    • In Windows' Power & Battery settings, select Best Power Efficiency

    🧬 Update BIOS: Ensure your system runs BIOS version 1.17, which improves thermal behavior and unlocks more performance flags internally.

    Start by elevating the rear edge of the laptop with a cooling stand or soft supports. This improves airflow and helps internal temperatures stay lower, reducing how aggressively the fans ramp up. Next, close background applications and unnecessary processes using Task Manager to limit CPU load, keeping temps down and fan speeds more stable. Finally, set Balanced Mode in Predator Sense and switch to Best Power Efficiency under Windows’ Power & Battery settings
