This is exactly what I pointed at in my previous point.
By reducing the fan speed, we are not solving the problem, but we are creating another problem.
The main issue is with the CPU that gets overheated soon, the fan speed's noise is natural because it just trying to do its job and cool down the CPU. If we just reduce the fan speed, this doesn't mean that CPU doesn't get overheated anymore! We are just going to break the CPU faster and introduce another problem.
