The fan on my laptop had developed a mind of its own. It roared, nonstop. Online forums offered a litany of complex tweaks. Set the CPU power to 99%. Fiddle with obscure battery settings. Nothing worked.
Then, a chance detour into Windows’ power settings. A single option: “Power mode”. It was set to “Best performance”. I switched it to “Best power efficiency”.
Silence. The fan now only whispers when under real strain. The simplest solution was hidden in plain sight.
