    Just wondering how I can tell which temperature is the most accurate. How do these programs measure temperature?

    HWMonitor is saying my CPU is at 53C
    CoreTemp says 43C
    RealTemp says 43C
    SpeedFan says 44C
    CPUThermometer says 44C

    I've always been told HWMonitor is the most accurate program for temperatures; why this discrepancy?

    HWMonitor isn't necessarily always the most accurate, most of us use it because it's extremely convenient, as it measures temps of just about every crucial part in the system.

    That said, I'd be more inclined to trust the temperature that the majority of programs read. In your case, I'd guess the real temperature is around 44C.

    Also, if possible, check to see what your TJ Max is on both your CPU and the config file in HWMonitor's install folder. I'm pretty sure it helps if they match up properly.

    To add to what others below have been saying, I have sometimes seen HWMonitor report my CPU as -23487596C, so it does have errors sometimes.

    They measure temps from the sensors on the mobo, GPU, and HDD's. The problem is on older hardware they can be unpredictable. I have a Vostro 1500 and HWMon in Windows 7 says my 8400m GS runs at 47-57c. In Linux using the Nvidia Powermizer utility my card runs at 37-42c.

    I have a Desktop where HWMon says my 120mm box fans intermittently run between 1500rpm to 17,000rpms :eek: or that my +12V rail is only putting out +1.73v :rolleyes:

    Whenever you use HWMon take it with a grain of salt. If it says your temps are 90c then you might want to verify that.

    HWMonitor (as well as CPU-Z) both tell me that my desktop's i3 is running a VCore of 3.8 volts. The BIOS lists it as a much more reasonable 1.16v, as the CPU has not burned up yet.
