No Fan Detected Error [How can I turn it off]

Hey guys! You helped me great last time so I was hoping for a little more advice :) 

A while back I swapped my PC into a new case which runs the fans through a fan controller, this means there are no fans plugged into the Motherboard; and when I turn on my system I get an error "No Rear Case Fan Detected" which I can just press F1 to skip. This is presumably due to me basing my build off a prebuilt system.

Anyway I am wondering how I can turn off this error, so I don't have to press F1 every time I boot, I realise I haven't give you guys too much information but I am not sure what you need.

Mobo: H-CUPERTINO2-H61-uA TX (Cupertino2)

Thanks guys :) 



UPDATE: I think I have a locked down BIOS, possibly because it was from a prebuilt? Instead of full BIOS I get "Hewlett-Packard Setup Utilities" or is that something totally different? I don't usually get involved BIOS wise sorry :(

Its pretty simple, in the bios of the motherboard is a fan monitor, to check if the fan has stopped working or as a warning if the rpm speed is too low.


There will be an option in the bios for each fan header of the board.
Cpu : Cha: fans.

Simply turn off or disable.
It should be found in hardware monitoring, or the power options section menu of the bios.


Or select in the bios the option of halt on errors to disabled.
Used the first option though.

Go into CMOS/BIOS and disable it. There should be an option.
You may need to have a fan plunged into the CPU header, so the MOB knows if the CPU is being cooled.
With most good MOBs you can throttle the CPU fan down.

Hmmm most likely you will need to have a fan plugged into your fan header.
Just plug the CPU fan into the CPU fan header and the problem should go away.

Try flashing the BIOS with the same version. That SHOULD unlock the BIOS. If that works, go in and disable the fan warnings, save and exit, and hope that error doesn't happen again! It will only happen again if you reset the BIOS or you renable the fan monitoring.
