    Hello, I have ordered a new laptop (HP 2230s) and I would like to keep an eye on the temperature of the proc for the first couple weeks. Does anyone know of a windows based program that will pull that info off the system board? I've used motherboard monitor on PCs before but I don't know if that would work on a brad new laptop.


    Thanks.

    I second HWMonitor.

    Also, see RivaTuner is you would like to see an OSD (onscreendisplay) of your GPU temp while gaming.

    I tried CPUID Hardware Monitor (ver 1.11.0 / driver ver 129), looks nice, but it shows my P8400 CPU core temperatures 5C lower than they should be i.e. it's probably using the wrong maximum thermal junction temperature.

    If your only interested in cpu temperatures there's also CoreTemp which can log as well.

    I don't really trust any of what is given free, I used core temp and it read 5c higher in temp than rightmark CPU clock utility?

    A lot of the later processors incorporate a Digital Thermal Sensor for temperature measurement. The reading from the DTS is a countdown to maximum specified junction temperature ie when it is 0 the core temperature is at Tjmax.

    For example if we have a DTS that reads 70 and has a resolution of 1C then,

    If Tjmax = 105C the core temperature would be 105 - 70 = 35C

    Now the thing is Tjmax is not the same for all processors, for example the P8400 Tjmax = 105C but for a T7400 Tjmax = 100C. Therefore if the wrong Tjmax is used the core temperature will be reported incorrectly. If HWMonitor uses a Tjmax of 100C for all CPUs with integrated DTS then some core temperatures will be right and some will be wrong depending on CPU.

    Hope this helps.

    P.S. CoreTemp (ver 0.99.3) shows Tjmax correctly for the P8400, whether it's correct for all CPUs or not, I do not know.

    Just a quick update.

    There is a file hwmonitorw.ini that is generated in the same folder as HWMonitor.exe when HWMonitor.exe is run for the first time. If Tjmax is found to be incorrect, as it was with my P8400, then it can be changed in this file.

    i put a shortcut to hardware monitor on in my startup menu. so every time i turn my computer on, the temps pop up and i keep the window around (in the background) when im gaming.

    I have used speedfan for quite a while now (on different laptops) and it has been pretty decent.
