If your DV9000 or DV6000 is overheating and you want to increase the fan speed with a BIOS patch then here is the solution. It took me several months searching for this so I’m trying to spread the word that there is a way to patch the BIOS ACPI DSDT to increase the fan speed. After reflowing my NVIDIA BGA assembly I made this patch so now I’m not worried that my computer is going to overheat again. My GPU stays between 49C and 58C. If you want to control the speed of your fan, read "How I Fixed My Overheating HP DV9000 Computer: Software Solution: Patching the DSDT" (http://icodehead.blogspot.com/2010/07/how-i-fixed-my-hp-dv9000-computer_02.html#Section3.4.2). There are other sites that show how to do this for other computers as well.
