I just bought this laptop powered by CPU Intel ultra 9 275HX.

I noticed that during gaming the CPU temperature is always stabilizing around 99-100 degrees but with a usage aroung 25%. During idle temperature is always in the 50 range.

It is normal? It seems quite high values during gaming.

    Hi, points to aggressive boost behavior: The Ultra 9 275HX may be spiking to high frequencies briefly, causing thermal surges even if average usage is low. Another possibility is Fan curve or BIOS bug: update BIOS with version 1.08 dated 2025/05/29.

    To turn off Aggressive Turbo Boost change the setting to Efficient Enabled or just enabled in Advanced Power Plan settings:

    Also in Predator sense use Balanced Power Plan, turn on Cool Boost and in Windows Power & battery settings set that to Best Power efficiency mode.

    now seems more normal behavior.(under stress 90 deg max) . maybe needed some time to apply all settings.

    Opinions?
