LianLi software or BIOS?

My current PC has a fan controller that lets you change fan speeds by turning a number of knobs.

Crazy, right?

If only there was some sort of calculating device that could do it for you as and when you needed to increase and decrease the cooling...

I disconnected my fan controller because who has time to manually change the fan speeds? I moved to FanControl a few years ago because it meant I could get rid of the last vestiges of the Asus fan software that seemed to break every time Microsoft brought out an update, and then I'd have to wait for Asus to bodge together a fix.
 
Back in the day, I found BIOS cycling fans up and down annoying, so I went with a HW solution and set the fans to provide sufficient cooling under load.

Now that I wear headphones all the time and have fantastic tinnitus, I’ll be going BIOS or FanControl on my next PC.

You can set manual speeds, but it's better to use hysteresis where you can set limits for fans only changing speed after a given number of degree changes over a given number of seconds. It stops fans cycling up and down when things are just peaking momentarily. For instance my fans don't change unless there's a temperature change of +/- 3 degrees over more than 3 seconds. It's smooths out the fans reacting to temperature.
