Best Software To Monitor Fan Speed On Your Computer

monitor fan speed

SpeedFan is a free software that can be used to monitor fan speed, temperature and voltages of components. These readings are based on a computers own monitors and can vary greatly, depending mostly on the motherboard. Each model has a different set of monitors that provide the information SpeedFan displays. You can use this information to configure SpeedFan to sound an alarm based on these readings.

This example is based on the configuration for sounding an alarm due to high temperatures. You can check your computers component manufactures to set these alarms, or you can use numbers based on your own experiences with your computer.

Most of the computers in use today have built in shut down tolerances. For example, this means that if a component reaches a certain high point the computer will shut down. Because we don’t know why this happened it seems like a random event. When these random shutdowns become a constant problem SpeedFan’s alarms can help us eliminate, or discover, some causes for the events.

Setup Notifications To Monitor Fan Speed

In my experience I’ve learned my PC can have problems with overheating when playing certain games and converting video files. To minimize the chance of destroying my CPU or motherboard I have set SpeedFan to monitor fan speed and notify me with a beep alarm when the CPU reaches 65 degrees celsius. Some people might find this too high, but based on my components and my experience it works for me.

After opening SpeedFan you will see in the upper right a large Minimize button and a Configure. Click on Configure and a page with lots of tabs at the top will open. Click on the “Events” tab and a pretty much empty screen appears. About 2/3 down there will be the word “If” with a drop down menu. Based on the temps readings you’ve seen when SpeedFan is open select the one that gets the highest. Mine is named Core but you may see another name. Next is a small drop down menu with four choices, < (Less than), =< (Equal to, or less than) > (More than) and => (Equal to or more than). I have selected =>. The next field you input a number, I have put 65 here, representing 65 degrees celsius. The next field is below the first row and says “For” with a number menu then “Times” This I set to 1, which that the first time it happens. Next field is “Allow every”…”seconds” Here I have 0 (Zero) set. Below this is the field “Then”, followed by another drop down menu. The choices here are Execute, Pop up message, Beep and Send Mail. This is the action SpeedFan will take if my CPU reaches 65C, so I select Beep. There are more fields that are left empty, and at the bottom there will be Add, Clear, Update and Remove buttons. Once Add is clicked the alarm is set. All the alarms and the actions taken will be listed above these configuration fields.

Anyone Can Monitor Fan Speed

Although this might sound complicated to monitor fan speed it is really easy to configure. At this point the list shows I have set SpeedFan to beep if my CPU temp gets to 65C or higher. Every monitor that is on the motherboard can be set as an alarm. This can include Fan speeds, Voltages or Temperatures. All of these, especially voltages and temps, can be the reason for seemingly random shutdowns. But now that I have SpeedFan set to run when my computer starts I know if my computer is getting too hot, even if I’m playing a game. As soon as I hear a beeping I know that whatever I’m doing is causing my computer to overheat.
