Intel D875PBZ Bonanza CPU Fan control

[deio]

Hello, I am new here, so please don't be angry with me, but I have an Intel D875PBZ "Bonanza" mobo and it hasn't CPU fan control, only system and chasis fans are controlled. Is it possible to patch its BIOS so it can control the CPU fan aswell? I know that it might be possible because IBM has implemented in firmware for their mobos and they are made by Intel. Thank you in advance. :)

Being a happy owner of Intel's 915GAV MoBo, I am looking for the ways to overclock it or at least to install Intel® Desctop Control Center and here is a link to homepage with Intel® Integrator Toolkit http://www.intel.com/design/motherbd/itk.htm
This utility is to help third party manufactures to edit their BIOS settings. May be it could be used for enabling overclocling with Intel MoBos too?
And what could happen with my system, if I would install BIOS for 915PBL MoBo, which supports IDCC to replace those for 915GAV?
