    Hello, sirs.

    When playing heavy games like Crysis 2/3, temps raising up to 85c/75c for CPU and GPU respectively, then seems ACPI trying to do thermal throttling CPU, but instead it locks and I see raised Interrupts in Process Explorer that hogs 25-30% of CPU constantly. I can't determine exact temp of this event, since it may occur 5-10 secs after I exited or paused game when temps lowered to ~55.
    But same time Intel XTU shows Thermal Throttling constantly 0% even if temp raised above 95c.
    I thought 85c/75c for CPU/GPU is not an overheating.

    xperf.exe shows huge amount of ACPI.sys calls. Tried to disable almost all devices in Device Manager with no luck. The only workaround is to go Sleep mode, then wake - DPCs disappearing, but this is not an option.

    Then I drilled bottom and installed two little 4x4 fans under CPU and GPU - temps goes down to 75/65 and no more DPC hog issues even after couple hours of 'Crysising' or 'Furmarking'+Prime95.

    BUT! This is a non-persistent solution for me, so I need help how to resolve this problem without fans.

    BIOS version 221, All drivers latest, but I've tried to install previous versions too.

    Other people encounters exactly same problems with different laptops, and seems no one resolved yet.

    Any ideas? Maybe buggy AML?
