    Question Best way to monitor CPU temp?

    I'm running 10.10 on a Dell Inspiron 1520 and am getting some discrepancies when i try to check the CPU temps.

    Conky lists 82 C and i8kmon lists 67 C.

    What is the best way to check the temp?
    Thank you,

    I am doing a little checking, and it really looks like i8kmon is specific for dell, and may be much better than the acerhdf that I have acess too. I found the info here if you haven't looked at it . . .

    http://linux.die.net/man/1/i8kmon

    It looks like there are lots of options for setting up the fan, which should help you if it really is running that hot. I'm really interested in what the panel apt or sensors command may say. I do know that my conky (I'm really not fluent with conky, but I have it and like it and have modified it a little) uses the sensors command to reprort the temperatures.

    i8kmon sounds like a pretty good thing with more options than acerhdf.

    Looks like you've got some good answers here. I just want to add that you can also check the temp by going to System > Admin > Disk Utility and check the smart data/run self test on your hard disk.

    Edit: Sorry, that's for the hdd.

    Does the disk utility give the processor temp, or the hard drive temp? On my machine, there is a considerable difference between disk utility temp and what is reported by sensors.

    Well, that is a good question. I installed the sensors and the applet for them. I thought the sensors were already installed since I went through the same list of probing questions when I set up sensors for Conky to use.

    In any case, now when I look at the panel I have 5 sensors with different temps.




    I don't understand what the differences are between Temp 1 Core 0 and Core 1. I thought that the cores were the CPUs. There are two on this machine so OK I get that. What does Temp 1 refer to?

    Then again under i8k temp 1 is called CPU.

    I don't know what acpi with the sub-heading THM means either.

    Under i8k I see two boxes for fans. Checking either or both adds an rpm number to the panel. I thought based on the i8k monitor I installed earlier that there was only one fan on this system.

    I'm pretty confused now.
    Thank you,

    Re: Best way to monitor CPU temp?

    I'd sure welcome it if someone who really knows what they are talking about could jump in here. I really don't want to mislead anybody.

    We have different systems, and we get different readouts and different output for the same apt.

    Just to give you an idea, my Computer Temp Monitor in the panel reads 50 c now. If I hover the mouse over it, it displays THRM: 50 C.

    sensors in terminal gives

    Adapter: Virtual device
    temp1: +51.0°C (crit = +100.0°C)

    k8temp-pci-00c3
    Adapter: PCI adapter
    Core0 Temp: +45.0°C
    Core1 Temp: -49.0°C

    and conky reads
    thermal 0 ok: 50 C

    My conky uses the terminal command acpi -t to get its display.

    I suspect your cpu is at 70 . I'm trusting (assuming) that temp1 and acpi both give the cpu temp. I have looked at core0 and core 1, and though on my system they can be slightly different from temp1, they are usually within a few degrees apart.

    Anybody else have any input? Think I may go to a reference book.
