I do run Windows also on this machine, but I don't know anywhere in Windows that the temperatures, etc, are shown. (This is almost certainly a reflection of my ignorance of Windows software.) However, according to Bios Setup=>Power=>Hardware Monitor: ------------------------------------- CPU Temperature: 66(C) MB Temperature: 25 CPU Fan Speed: 1513RPM VCORE Voltage: 1.536V 3.3V Voltage: 3.328V 5V Voltage: 5.053V 12V Voltage: 11.520V ------------------------------------- which fits in pretty well with some of the lm-sensors readings. The CPU temperature varies astonishingly on this Athlon 64 machine. If I leave the Hardware Monitor running, the temperature steadily rises from 35C to nearly 70C. The fan speed seems rather low, by comparison with other machines I run. I thought of changing the fan, until I read of attempts by others with this machine (Targa), where I saw pictures of an expert apparently boiling CPU + heatsink in a frying pan, as the thermal grease apparently goes solid - this man reported that his CPU temperature reached 101C, which I find puzzline, as my machine halts, I presume when it reaches some critical temperature. > If the "Motherboard Monitor" program has information > on your motherboard in its list, that might also tell you how > to calibrate things (but I think the author gave up trying to > keep up with the impossible task of figuring it all out). > > Motherboard Monitor is at: http://mbm.livewiredev.com/ Thanks very much, I'll try that. I did try the program mbm5370.exe. which someone recommended, under Windows, but I didn't find the output any more comprehensible than lm-sensors. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
