Highspeed Gentle Typhoons are wonderful beasties. They run at 300, 4250 and 5400 rpm but sound surprisingly quiet for those speeds. They draw their power from the PSU so they don’t burn out your motherboard. They even report their RPM with a dedicated line. All they lack is PWM. With PWM control our motherboards could tell these fans when to really crank, and when to be quiet. But take heart! Hiding in highspeed Gentle Typhoons are the reins to controlling these fans. I just bought a new highspeed Gentle Typhoon. Inside half an hour I can turn this wild critter into a docile PWM fan. Follow along with me and learn for yourself.
