    What is your idle CPU temperature?

    My idle cpu temp is 45 C.

    Specs: Xubuntu 12.10 64-bit, Sony Vaio laptop, quadcore i7, amd catalyst graphics card driver

    I started this thread because I want to know what is the "normal" cpu temp on Ubuntu. I know on Windows 7, the idle cpu temp is much lower than 45 C. Through power saving tweaks and the kernel power regression fix and the Jupiter applet, I have lowered the idle cpu temp from 55 C to 45 C, but I want to get it as low as possible.

    Depend on ambient temp and their own spec.

    Zalman cooler on an AMD 965BE, CPU Fan tuned to silent, 6 web tabs open and no case exhaust fan I've got 33 degrees C. CPU 'danger level' as stated by AMD is 60 + so I guess 33, 34 is normal and I'd not expect to see 40 even transcoding video or converting files. (I ran a youtube video and it dropped to 32).

    40-50 on a sony vaio VPCZ2; also a quadcore i7

    no special tweaks, just using lightweight XFCE as I found out I don't need anything of Unity/Gnome

    I'm in Ubuntu 12.10 and have an intel Core2Quad Q8400 my temps at idle are 53 C. My max temp for this cpu is 70 C, sorry for the edit, and my GPU is a NVidia GTX 650 running at 33C at idle

    How are you all estimating the temp?
    You think that's air you're breathing now?

    I've got a crappy core 2 duo on a laptop -- and looking at the system monitor applet -- its part of cairo dock -- it says
    Core 1 64 degrees, max 105
    Core 2 63 degrees, max 105

    I have no idea if these monitoring apps are even calibrated -- just saying

    Just install lm-sensors and run sensors in the terminal. More info here: https://help.ubuntu.com/community/SensorInstallHowto
