SpeedFan vs. SIW temperature readings

    SpeedFan gives the temp readings for my Dell XPS M1530 as follows:

    HDD: 32C
    Core1: 40C
    Core2: 40C

    SIW gives the same temps as follows:

    HDD: 32C
    Core1: 55C
    Core2: 55C

    Which program is more accurate, and what could possibly be the reason for different CPU temp readings?

    The best way to find out which is more accurate would be to reboot the PC and go into the BIOS and check the hardware monitor/PC health and see what it reports. To be honest, I have never been a fan of SpeedFan for this very reason. On one PC it would jump around dramatically from 35c to 87c to -21c to 438c.... I'm not exagerrating! It was ridiculous. I tried PCWizard and HWMonitor on the same PC, and both had stable readings that were pretty colse to each other; within about 2-3 degrees. It could have been that SpeedFan simply didn't have that particular motherboard/sensor it its database or whatever. Anyway- try HWMonitor and PCWizard, and check your BIOS. It could be that SIW is reading the CPU temp and SpeedFan is reading the system temp, or vice-versa.

    I hope this helps!

    I tested with HWMonitor and Core Temp to verify SIW's accuracy, then found a calibration/offset entry within SpeedFan. All good now!
