Question CPU running above threshold!!!


Hi Folks,

I've been using Fedora merrily on my rather old machine..... Last month i brought a machine with the following config

Intel Dual Core 2.66 Ghz
Intel Original Board D101
1 GB DDR-RAM
80GB SATA HDD

I installed FC5 on this machine which was a breeze..... But when i get to the desktop or even for that matter at the konsole i get message saying that "CPU is running above the threshold frequency/temperature" n keeps poping up often. I opened up the case to see any symptoms of heat but all seems to be fine!!!!!!!!!!

I tried installing RHEL4 and it installed two KERNEL IMAGES, one with SMP Support n the other regular KERNEL.... If i happen to boot into the SMP KERNEL then i get these pop up's, but on the other KERNEL no such pop up's are displayed nor any such entry in "/var/log/message" . The machine runs perfectly fine......

I also tried installing a few other distro's like SUSE, KUBUNTU. Messages were logged in "/var/log/message" though no pop up's appeared in SUSE(It uses a SMP KERNEL). KUBUNTU does not complain as it does not install a SMP KERNEL.


Could any one help me out on this? Thanks in advance

Most likely a BIOS or ACPI bug if the CPU is really running at the proper temperature.

It's possible that the CPU heatsink isn't properly installed. If you're comfortable with messing with hardware, try reinstalling the CPU heatsink (properly cleaning off any old thermal interface material and applying new thermal interface material).

Thanks for the quick response, any tips on how to figure the BIOS or ACPI bug??????

Isaac, i myself had setup the machine...... so will cross verify heat sink stuff you suggested n will revert back.Thanks

I got these messages on my old P4 3.0GHz as well, I grabbed digital probe thermometer and stuck it in the fins of the CPU heatsink and it was running at a perfectly acceptable temperature so I ignored them. Maybe go to some extra lengths to make sure the CPU is in fact at the correct temperature and if it is I'd just pretend the messages don't exist.

Make sure to keep an eye on it though as a burnt out CPU is an expensive lesson in memory.

Hey could it be you are trying to install the FC5 smp kernel instead of the standard??

I doubt it. Anyhow, he will need the SMP kernel to take advantage of both processor cores.

To the OP, are there any useful tidbits in the /proc/acpi/thermal_zone or /proc/acpi/fan directories. Maybe the thermal threshold is set too low -- old Pentiums (at least the Xeons, and I imagine the P4s too) do tend to run fairly hot, but this is normal.
