The best way to check if your fans are working correctly is by using diagnostic tools. There are both hardware and software tools available for this purpose.
Hardware Diagnostic Tools
1) Fan Tester: A fan tester is a device that is used to measure the speed of a fan, diagnose any problems with it, and identify any issues related to the fan’s efficiency. The tester measures both the speed and quality of the fan blade rotation, and can provide useful data about the fan’s overall performance.
2) Volt Meter: A volt meter is a tool used to measure the voltage output of a fan. It can detect problems such as worn bearings, blocked filters, and over/under-voltage problems.
3) Thermal Imager: Thermal imagers are used to detect heat levels in different parts of a fan. This device is commonly used to inspect bearings, motors, fan blades, heatsinks, and other components of the fan. By detecting the hot spots on the fan, it can help identify any potential problems.
Software Diagnostic Tools
1) Fan Control Application: Many modern fans come with their own proprietary fan control application. This type of software is used to monitor and adjust the speed of the fan and also to enable or disable various features such as LED lighting or noise reduction. With the help of this software, you can check if the fan is running properly or not.
2) SpeedFan: SpeedFan is a powerful Windows-based application that can detect the temperatures of various components in your system, including the fans. This tool can tell you the RPM of your fans and also change their speed using PWM controls. This can be useful for monitoring the performance of the fan and making sure it is running properly.
3) HWiNFO: HWiNFO is another popular tool used to monitor system temperatures, fan speeds, and other important information. This software can also be used to check whether the fan is in an acceptable range or if it needs to be adjusted.
These are some of the most commonly used diagnostic tools used to check whether your fans are working properly or not. If you experience any issues with your fans, then you should use one of these tools to diagnose the problem and correct it as soon as possible.
