Anyone that uses his/her PC computer every day should leave it on
24/7. The added benefit for Linux users is that cron jobs will be run
overnight, usually 4am. I run a Tbird at 1.55 gig and I never shutdown
'cept about 15 minutes into a power failure before my UPS battery runs
out.
Any PC user at all concerned about heat, should enable temperature
monitoring. Run 'which sensors-detect' in a term as root. If it
returns '/usr/sbin/sensors-detect' you're good to go (maybe). If it
doesn't install the 'lm_utils.....rpm' from your CD's. Then you can
type 'sensors-detect' in a term (as root), and it'll configure sensors
for you and generate a few lines you need to add, some for modules.conf
and some for rc.local. Read the doc's. You don't haft'a, but the
easiest thing to do is reboot. That done, typing 'sensors' in a term
(root or user) will display your systems temperatures, voltages, and
fan speeds. You can also use Gkrellm to constantly update and dislay
the cpu temp and other values. 'sensors' in a term only displays the
values at the instant it's run. BUT ....
For any of the above to work, your motherboard must have full
hardware support for i2c monitoring. Many readymades from 'vendors'
don't. Specially Intel OEM ONLY (spec) boards. Also, your BIOS may
have an option to turn off fans when the computer goes into power
saving. Disable this, keep your fans running. It's also a bad idea to
let HDD's spin down. They're much better off constanly spinning.
If you get to the point that 'sensors' does display temps, then d/l
'cpuburn' from http://users.ev1.net/~redelm/ Then when running
'burnP6' for at least 30 minutes, if your Celery will stay under 50C
(internal PII diode, 45C would be better) you're completely safe to
leave your system on 24/7. While running 'burnP6', if the cpu temp goes
up to 55C, abort burnP6. If the cpu temp won't stay at or under 50C,
you've got hardware problems in the making whether you run 24/7 or not.
You'll need to improve the cpu's heatsink/fan and case air flow. I'd
caution you that readymades usually have marginal to poor hs/fan's and
case ventilation. Just another good reason to build your own PC ;>
