I have a very similar configuration with the same CPU Fan Error on boot.  I thought it was due to the fact I don't have a CPU fan hooked up to the mobo.  I have a water cooled CPU so it would be nice to find a remedy to the CPU fan error. 

I'm going to check the BIOS settings to see if there is a way to disable the message.  I'll let you know if I find a way to disable it.

In the mean time does anyone else have a remedy for the error?

Hi A...

Are you using the Intel retail fan or something else to cool the processor...?

If you go into the BIOS under the BOOT menu you can disable the Wait for "F1" if error selection.  I tried it and it gets rid of the Fan error but still doesn't explain why the fan error occurs.  I would still like to know so if anyone can shed some light on the subject that would be beneficial.

When water cooling you need to set the rpm monitoring for the CPU fan to Ignore.

Then the F1 message goes away.

I am NOT using the Intel retail fan. I am using the Vigor Monsoon III LT fan. The details of which can be found at http://www.vigorgaming.com/components/cmp_monsooniiilite_intel.html

FYI, it comes with a 4 PIN wire and I hooked it properly to the CPU_FAN connector. I was NOT getting the error till BIOS version 0805. Starting from BIOS 0903 this error is being poped up on every COLD boot up.

I do not want to disable F1 error message so that i know about any system errors but would like to find a solution to fix this problem. When the error is shown, I can see the fan working properly. What can I check to find the exact problem so that I can report it to ASUS technical team to get a fix for it.

Hi A..

Have a look in your BIOS hardware monitor at the CPU fan speed.  In most cases, you will get an error if the fan is running below 600RPM. 

If you have Q-Fan, enabled, disable it and see if the error continues or enable Q-Fan and set the profile to 'Turbo' and see if the problem continues.

I am experiencing a similar issue with my aftermarket fan (Thermaltake V1)... With mine I have it cranked to the fullest at all times. I started getting this error and when checking the fan it was running. So I just hit F1 to skip the error. Over time every so often I would get the message and check the fan and it would be "twitching". So I would hit reset on the case and it would reboot normally and the fan would engage in a normal fashion. Now I am getting it on every boot. I have no luck with the reset "cure" and I have to skip the error with F1 and hope that by the time Vista finishes booting - it is running normally. Sometimes it is - other times I don't see it engage until 5 minutes into my window session - if at all. So - for me basically it isn't an annoying meaningless error coming up. It started that way, but has blossomed into something serious either with the cooler itself or the motherboard not pushing enough consistent juice to the fan to get it moving. Is there a cure or should I be looking at returning the board/cooler?

Hi D..

Is the fan a three wire DC fan and does it have its own speed control adjustment switch...?

There should definitely be an option to disable cpu fan monitoring or to ignore it.  Look around where QFan is in BIOS.
