AI7 and Siren + fan noise on Boot

External Since: Feb 12, 2005 Posts: 4

Hi,

I have an now 2 month old AI7. It has some annyoing issues. The first is the
NB fan makes a grinding on booting, for a little while. Its only spinning at
like 2000-2500 rpm. It eventually jumps to 5000 and stops making noise.

Anyways, sometimes or in lieu of this I also get the Hi-Lo siren. I go to
the bios. It looks like the only thing out of normal is the NB fan.
(Northwood 3ghz cpu). Sometimes it goes for 1/2 a second, sometimes it goes
on until i turn off/on once or twice.

Sometimes it seems to "slow" down and then stop. Sometimes it starts up
again.

Could this be the NB fan causing this? System temps on bootup are like 60F
for case, 70F for PWM, 75F for CPU.

Any ideas?
Thanks,
-Adam

the temps are probably in C as opposed to F as if they were really F, then
your system is running niiiiice and cool! even still, the stalling or noisy
NB fan could be the cause of the alarms because the alarms are generated by
temperature problems, monitored fan problems, or voltage problems. you
could always either replace the NB fan with an aftermarket or temporarily
disable fan monitoring in the bios, if available. then see if the issue is
resolved.
