Frequently Asked Questions

What Causes Computer Fan To Speed Up?

There can be many possibilities for a computer fan to speed up some of them being a heavy load on the device, excessive files, and downloads or heavy applications running. Some other features that can trigger this are faulty heat sensors and high temperatures. To avoid this from happening use SpeedFan or buy External Fan Controllers.

What Is Good Fan Speed?

A good fan speed has not yet been defined, you can never tell what the right amount of fan speed may be which is why automatic software such as SpeedFan are handy as they keep a check on the CPU’s heating system and the Fan’s speed correspondingly. A balance needs to be kept between the heat and cool. You need to keep a check on your RPM’s as they shouldn’t be too high or too low. High RPM’s can create a lot of distortions and loud noise whereas low RPM’s can cause heat-ups. The CPU fan should be adequate to sustain the temperature within a safe zone.
