    I have a dv4t with a T5800 and I have a few questions about the T5800.. hope someone can answer them.

    1. How new is this processor?

    (Because all temperature monitoring software I test (Real Temp, Core Temp, HwMonitor) give incorrect readings or the temps (whether too low e.g 20C or too high 70C) and the programs also don't show the change in temperature (e.g even when I am using 100% CPU, I still see 28C).

    Does this have to do with the ACPI drivers that HP make?

    2. Why do most of the programs show the T5800 as a T7250
    Is this another ACPI driver issue?

    Which program can I use to get the correct temps?

    Yes I did sorry I forgot that same thing This is what it shows:

    EVEREST:
    Sensor Properties:
    Sensor Type CPU, HDD, ACPI

    Temperatures:
    CPU 65 °C (149 °F)
    CPU #1 / Core #1 24 °C (75 °F)
    CPU #1 / Core #2 28 °C (82 °F)
    Hitachi HTS543225L9A300 [ TRIAL VERSION ]

    Voltage Values:
    CPU Core 1.35 V

    HwMonitor:

    EDIT As you can see HwMon see the 60C - 70C reading as the 'THRM' which I suspect is the northbridge (chipset) temperature but in everest it says 'CPU' is 60C 65C.
    Which one is it?

    Yes the fan is on always on.... Sometimes its not loud when mystery temp (THMR) is 58C-65C , but when it goes to 66 - 78C! the fan gets loud.

    There is an option in the BIOS to turn 'FAN ALWAYS ON' I would set it to off because sometimes the fan is louder than my liking. But not with how the temps look now.
    Can I turn that option off?

    Let the fan setting be on Auto or off.

    Software haven't been updated to support the DTS of some new gen CPUs, even though the T5800 is based on the previous Merom core.

    Till then, go by the ACPI temps. THRM is the Thermal Zone #0. It seems that the fan-temp table is based upon the THRM temps, so you can define the CPU core temps using the THRM +/-5*C.

    Thanks a lot man Andy :)

    One more question, Do you know any notebook coolers that are known to work well with the (cooling system of) dv4t?

    TBH, I am not sure. Better check out this guide and the Cooling Central.
