How best to limit Lite-On LH-20A1P burn and reading speed?

I have wanted to limit read and burn speed to make the drive not so loud but firmwares I find are to speed or overburn not make slower. Is there a good way to slow the drive with firmware patching or something like that change in the firmware?

Thank you

This is supposed to have a slower speed when burning 8X or 12X.That is the FBL part of the flash.The lite-ons of this series are not quite anyway.

Thank you for reply

I will read at the link you give to find the answer. If I am not understanding it well, may I ask about that next?

Thank you
