Make a P8Z68-V Pro think there's a fan

wkingsnorth · 11 Feb 2012 at 11:05

Hi, I've got an Asus P8Z68-V Pro, and all my fans are controlled via a fan controller. The problem with this is that even if you tell it too, it refuses to ignore that there is no CPU fan, and so booting up takes an extra 10 or so seconds, and makes the beep code that gets annoying after a while. So basically, is there a way of making it think there's a fan attached without actually attaching one?

Hmmmm had to RMA mine so I can't check, but I am sure there was an option in the bios to disable the fan check?

Yeh I think it still displayed that no fan was connected but it didnt make me enter the bios or press F1 etc?

I've set it to not wait for F1, but tell be about the problem and continue with normal start up, that's all I can do.

Try and modify a fan cable so the RPM wire can be attached to the CPU fan header. That would report the fan speed only and the motherboard would no longer moan about it.

There is a bios update that solves this problem. I had the same problem, updated bios and boom, it was sorted.

Call me a noob, but how do I go about flashing the bios exactly?

I'm sure Asus have a Windows based BIOS updater, take a look at their website under downloads and utilities.

Andi.

Any chance of this doing damage to the motherboard at all?

Ok, do I download bupdater utility from the website?

Yes, unless you've got a dual bios. Don't flash it from windows. If you BSOD you might brick the board.

Check your mobo manual on how to flash the bios out of windows. ASUS has an EZ-Flash updater option in the bios on older boards so you should have something on there too.

Is that damage could be done when windows is used, or damage could be done fullstop?

Did that, and now it works perfectly

Flashed to 1101 and it works fine, thanks all

Damage can still occur when flashing out of windows if you have a powercut.

It's always risky however Windows is worse as a bad driver may cause it to BSOD whereas in the BIOS flash utility there isn't much loaded to crash the PC.

Some motherboards have dual bios's so if you have that then you can never damage it unless you're an idiot

Good to see you got it done safely. Using the flash utility is much safer than one in Windows or any OS.

best thing bout asus boards though is you can pull the bios chip and plop in a new one,gigabyte bios's are soldered

O rly? I shalt google this. Not that I'll need it any time soon...
Or will I? Something could always go wrong...

Only if you break it whilst flashing.

Pretty sure in 99% of cases you can't damage your BIOS by normal operation.. unless you put your foot through the board or something!

wazza300 · 11 Feb 2012 at 22:19

look on fleabay,plenty z68 pre flashed bios chips,they just pull out and push a new one in

Only if the power goes out whilst flashing. You won't need it.

You could always buy a ROM flasher and just reflash the chip out of the board and put it back in.

Never knew gigabyte soldered theirs in. Pretty silly if it hasn't got a backup bios.
