    Default CPU Temp's and BIOS update

    Bit of a strange one really..

    My CPU was running around 35c idle with the CPU fan running at around 1100rpm (SMART Fan)
    Since upgrading to the newest BIOS revision my CPU temps have risen to around 48c idle
    Slightly concerned I decided to go back to the older BIOS revision, straight away my CPU temps dropped! or did they?

    I downloaded Everest as I know I could check specific core temps here's what I found;

    Old BIOS - Idle
    Motherboard : 25c (I've never seen this change)
    CPU : 36c
    CPU 1 (core #1) : 35c
    CPU 2 (core #2) : 34c
    CPU 3 (core #3) : 36c
    CPU 4 (core #4) : 37c

    New BIOS - Idle
    Motherboard : 25c
    CPU : 47c
    CPU 1 (core #1) : 36c
    CPU 2 (core #2) : 34c
    CPU 3 (core #3) : 36c
    CPU 4 (core #4) : 33c

    Also I have noticed with the newest BIOS revision I still can't get below 40c even running my CPU fan at MAX (4550rpm)

    So my question would be do you think my CPU is actually running at the higher 45/50c or do you think this is misleading information from the temp sensors?

    I have asked Shuttle direct but they said update the BIOS with the following command strings, which I did and surprise surprise no difference..

    The newest BIOS revision allows compatibility for 45nm CPU's and added PCI-Express compatibility so could roll back anyways I guess..

    Ohh my spec's are;

    Shuttle SG33G6
    Intel quad core Q6600 (G0)
    2gig OCZ Plat Ram
    Samsung Spinpoint 500gb HDD
    DVDRW
    blah blah
    Vista x64

    I suspect it's more likely that the new BIOS has corrected a temperature reading problem rather than the CPU running hotter than before.

    Temp readings from 3rd party software can vary wildly depending on how accurately the sensors communicate with said software, what temp is reported in the BIOS?

    Horsepower is how fast your car hits the wall
    Torque is how far your car sends the wall across the field once you've hit it

    Thanks for your response Pegasus.

    The BIOS seem's to agree with Everest, to be honest I'm unsure if this is even hot for my CPU? (at this Fan speed)
    Still can't seem to get below 40c though which is odd!
    The separate core temps seem to reflect a cooler CPU but obviously in the BIOS there not specified.

    It's more that this just annoys me than causes a problem

    47° is nowhere near hot for that CPU

    Glad to hear it, I really hadn't the foggiest!

    Thanks again Pegasus
