why not just set maximum speed and forget about it?

why not just set maximum speed and forget about it?
- cadamsdotcom 4mo agoThere are two types of nerd - one who optimized fan speeds and one who just lets ‘er rip for max compute ;)

This means the fan should run as the lowest speed which maintains a reasonable temperature, so at the very least there should be some kind of mapping between temperature and fan speed. However, a rapidly-changing fan speed results in a more annoying sound than a slightly faster fan, and chip temperatures can ramp fast, so a simple linear mapping between temperature and fan speed isn't enough. To get a quiet fan in an environment where you are, say, loading the CPU to 100% for 100ms every second, the fan controller should be able to average out the heat production and let the fan run at a steady speed. After all, the cooler is a big chunk of metal, so its temperature will never ramp as fast as the core itself, so a rapid fan speed response is pointless.
