Core 2 Duo E6400
ASUS P5VDC-MX

During installation everything was fine, no complains no thing.

After a night out in the back of the card (freezing temp), and powering up the machine at the clients office.

Everytime this thing boots up complains about FAN error, press F1 to continue.

Very well, go into BIOS and see FAN spining around 800~900 RPM

you let it boot to WinXP, everything works fine, restart the computer, and no more complains, check BIOS, FAN spining at 8000+ RPM (around 8600~8900+)

and it works fine for the rest of the day, but if you turn it off, then turn it back on the next morning, **** thing does the same FAN - F1 error message again?...

What gives?

there's nothing phsycally wrong with either fan or mobo, or the power.

is only during the 1st power up of the day, that does that weird thing, when everything is Cold (room temperature) that's around 15c

Yet it never complained when it was in my place during install (room temp around 20c)

is the morning air too cold for the CPU FAN?

This is the Retail boxed FAN that came with the Core Duo

The fan is plugged to the ASUS mobo into the CPU Fan plug.

What could be wrong with this thing? the Mobo? the Fan? the PSU?

but if it's any of the above then the problem should happen all the time, not just during the 1st boot of the day. :frown:

Hehehe I was surprised a little by this as well.
When i put together my Core 2 Duo 6600 and fired it up, I was about to shat myself because the fan didnt spin up.

It appears the retail fans are heat sensitive. It spins according to the heat generated. When you first boot the thing it is cold and the fan sit idle until it heats up and then spins up.

I disabled my fan warning in the bios to alleviate the annoying beeping.

ok thanks for the confirmation, that's what i though... but it sure is annoying.

I guess i'll dissable the FAN warning as well.


is kinda weird my own Rig doesn't complain about that at all, but on the other hand it would probably never will, since i keep my rigs running 24/7 :D

I am not sure what the threshold is for the fan to start spinning. It only happened to me once in the first 2 weeks outide of the first powerup I had the thing and it was really cold in our house.

But it was annoying enough to disable the fan warnign in the bios hehe.
