Not only such behavior is much more pleasant on ears, it also cools internals more steadily instead of leaving them scorching hot as it instantaneous cuts fan speeds. Benefits of this is that chassis fans can follow entirely different fan curve, react to heat inside chassis instead of CPU and when workload is done, fans remain running at elevated speed and slowly go down as chassis internals fully cooling the inside of chassis. Which usually fluctuates way less and remains high for longer after heavy workloads. What this means is that you can set CPU fan to react based on CPU temperature where chassis (case) fans can react based on SYSTEM temperature. Fan control separated into CPU and SYSTEM sensors, meaning you can set fans to ramp up through a defined fan curve based on CPU temperature or SYSTEM temperature for each individual fan. Especially fan controls are nothing short of spectacular. And it had one of the best BIOS-es I’ve used in decades. Till very recently when I upgraded to AMD Ryzen 5800X with ASUS Strix X570-E Gaming, I was running Intel based system with MSI X99A Gaming 7 motherboard.
