    I think for most Intel CPU's, they say 100C is the max cpu core temp.
    About 70C is "average to heavy usage".

    Assuming the PSV means passive cooling marker, the CRT means critical
    temp mark, and AC is active cooling marker, I don't have any idea what
    HOT is - so:
    Passive cooling up till 3632, or 90C
    Active cooling until 3582, or 85C
    Critical state at 3732, or 100C

    The active/passive numbers look switched to me - unless I've
    misinterpreted the abbreviations (most likely).
