So I set myself the task of reviewing the other fan speed control applications available. Speedfan’s interface isn’t the easiest to understand and use, and you’ll be glad to know that there are some good Speedfan alternatives out there. In most cases, you’ll want to use the application to speed up the fan because your laptop is in danger of overheating.Īlthough Speedfan is popular among Windows users, it’s not the only program in town. Sometimes a computer doesn’t run too hot, but the fan makes too much noise when it’s whirling around at high speed. With Speedfan you can increase or slow down the speed of your fan. You can use Speedfan to change the speed of your computer fan when it gets too hot inside. Speedfan not only evaluates fan speeds, but also measures temperature and voltages. For many Windows users, Speedfan is the most important application for controlling fan speed.
