    Why does HWMonitor and HWiNFO32 report very different temperatures on my Dell XPS m1530

    You're kidding, right?? The Value number reported is the current reported temperature - a 1 degree fluctuation is hardly "very different". The Min/Max values are just that - upper and lower limits, and temperatures fluctuate fast enough that a monitor program can record the a value that changes a second later.

    The primary report number you should be concerned with is the current temperature value for the component being monitored, and as you can see, they're extremely close.

    You have to remember that system processes and CPU tasking are all changing at a very rapid pace, and that affects temperature at given points that are being monitored. It would be of concern if one was say, 10 degrees different than the other, but it's not.

    Min and max temps are generated from the time the program was initially opened.

    They look the same. Really!

    Ok, look at the Value column in HWInfo32. CPU Core 0 and 1 has temps of 49°C, hard disk (the one under SMART) has a temp of 31.0°C and the GPU has a temp of 64.0°C. The embedded controller, I think, is the temperature of the motherboard. Average of around 50°C.

    Now look at the Value column in HWMonitor. CPU Core 0 and 1 has temps of 50°C and 49°C respectively, hard disk has a temp of 31.0°C and the GPU has a temp of 63.0°C. The THM_ is the motherboard and has a temp of 47°C

    The small differences between the temps of the components can be due to sensitivity of the sensors and of the programs.

    As for the big difference between the maximum and minimum temperatures between the two programs, I believe it is due to you opening HWMonitor first, before you opened HWInfo after or while running an intensive program. The programs will only start recording temperatures when they are opened. They don't record temperatures in the background.

    They look the same to me. Small differences can be from the scaling in the program.

    Lol, those are just about spot on. Try comparing HWMonitor, CoreTemp (.995), and TAT all seem to report differing numbers (by up to 10c on CPU temps).

    Heh, I love how the article says 'it will display correct CPU temperatures as you may verify with CoreTemp'...yet it is HWMonitor that is actually showing 10C higher than CoreTemp when used on my Penryn core T6400. The article says it will read 5C low.

    Still wondering which is correct.

    On my 1640, HWMonitor is reading exactly 5C lower than temps reported by Core Temp. I believe CoreTemp's readings are more accurate though.

    im using t9500 and the temps reading between hwmonitor and core temp is different too.. the core temp is usuallly +5 degrees more compared to the hw monitor.. so which is really more accurate? hwmonitor or coretemp? :)

    CoreTemp definitely reading 5C lower. I'll stick to HWMonitor since it'll be the first to reach higher temps. Better safe than sorry~

    Okay, that was weird. Now CoreTemp is 5C higher than HWMonitor. I'll just stick with HWMonitor as always...
