Re: CPU overheat crash during kernel update.

Under KDE, there's an icon that gives you an overview of the computer.
This includes using ACPI to read the temperature of the processor. For
some reason, no matter what the load, or what sensors says the processor
temperature is, it always seems to read 40C.

With KDE 3.5, I use the Ksensors front end to sensors. The initial settings
give obviously incorrect readings - the CPU is below room temp! I use an
IR thermometer to get the highest temp in the case and around the CPU then
apply a multiplier to get the displayed numbers to a more realistic value.
On my machine, the temps obviously track CPU and disk load so it's sort of
like my truck - when the needle rises above it's normal resting place, I
take note. If it shoots toward the high side in a hurry, I got problems!

lmsensors and gkrellm
No you do not need the full gnome desktop for gkrellm


I have to clean the carpet dust, dead bugs and other muck out of the
power supply, cpu heat sink and fans every 3 month or so to prevent
overheating. Keep the fan's leading edges clean or loose significant
airflow.

Pet hairs, especially those from long-haired cats, are another killer of
PSUs and fans.

Suggestion: clean/vacuum as much as you can get then reverse the machine and
blow back into the power supply through the fan. Vacuum the inside ps
vents thoroughly after that. Reason is that the ps fan pulls a pretty good
flow through it that piles up the junk between wires and parts which you
pretty much have to hit with a direct reverse flow to dislodge. I'm a
smoker with 3 dogs and a wood shop in the next room so this is a must do
for me about once a month.
