I don't know about the bios update though. More power = more performance = more heat to dissipate with the fans. Like one profile for when you are at home and are less concerned about the noise level and another one for when you are out there and just want to use your laptop for basic office tasks, quietly. You can set different profiles in Throttlestop or XTU to modulate the desired performance and change the fan curves accordingly. When undervolted, power reduced for PL1 and PL2 (or even 'Turbo Boost' disabled for greater effects), and fan curves adjusted to spin at the minimum speed (minimum is ~2100 rpm, which is barely audible) unless reaching a temperature that is reached by doing something actually cpu intensive (more than web browing), you can actually use the laptop in a quiet environment like a classroom or an office. To run the laptop cooler (so easier to cool down with the fans), you need to undervolt and also reduce the power to the CPU using Throttlestop or XTU (can also easily be done under Linux). Mine out of the box runs in the 70s at idle, even 80s when I watch a video on the web and open 2-3 new tabs. You can use Dragon Center or SilentOption (on Windows) or isw (on Linux) to change the fan curve. Out of the box, it is hot and wild, so the fans start spinning faster (so louder).
