Excellent article. However my laptop is a newer model and none of these actually work. As far as i see, my laptop has 4 fan levels. When offset 103 and 105 are 4, the fans almost dont spin. And when they are 01, they are spinning in the fastest mode. Laptop almost always runs in 04 and its almost silent. But it gets extremely loud during gaming cause the fans go to speed 01... However this is overkill. The noise in 02 mode is very acceptable and going to 01 drops temps about 5 degrees (75 to 65).. I checked my DSDT file, i have absolutely no programming experience and couldnt understand much. How could i find out the register which indicates "Max Fan RPM Value" and keep the fans from 01 no matter how hot it is?
