5 Best Free CPU Cooling Software For Windows

Here is a list of best free CPU cooling software for Windows. These free software are very useful as it is very important to keep CPU and overall temperature of the system under control. The first and foremost method to maintain and reduce the CPU temperature is to increase the CPU fan speed. By default, the system BIOS control the CPU fan speed according to the temperature of the CPU. However, it is not very efficient as it takes time to react that leads to system overheating and throttling. To tackle this problem, I have compiled a list of CPU cooling software which effectively reduce CPU temperature. In most of these software, you get both the manual and automatic methods to control the CPU fan speed. Some CPU cooling software also use CPU frequency reduction method to reduce CPU temperature.

Most of these are also really good at monitoring system parameters like CPU, GPU, HDD, etc. temperature. Plus, features to monitor real-time CPU fan speed is also provided by most software.

My Favorite CPU Cooling Software For Windows:

SpeedFan is my favorite software because it is one of the most effective software to bring down the CPU temperature. Besides managing the CPU temperature, you can also use it to monitor system parameters like Vcore Voltage, HDD Temperature, CPU Frequency, etc.

You can also check out lists of best free Fan Speed Monitor, CPU Usage Monitor, and CPU Temperature Monitor software for Windows.

SpeedFan

SpeedFan is a free CPU cooling software for Windows. Using this software, you can manually control the CPU fan speed when your CPU is running hot. To control the CPU fan speed, it provides an advanced PMW function that lets you increase or decrease the fan speed by sending the pulse modulation signals. By increasing the CPU fan speed, you can immediately bring down the temperature of your CPU.

This software can also be used to monitor various system parameters like Vcore Voltage, CPU Temperature, Hard Drive Temperature, CPU Frequency, and more. It also has some advanced features namely Clock (to overclock CPU frequency), Hard Disk Analyzer (to perform online in-depth analysis of hard drive), Chart (it shows a graphical representation of fan speeds, temperature, and voltages).

KAR Energy Saver

KAR Energy Saver is another free CPU cooling software for Windows. As its name implies, it is mainly an energy saver software that tries to save as much energy as possible without slowing down the system. It uses two main methods to manage the power consumption and cool down the CPU. The first method is to smartly manage the processor frequency according to the load which prevents CPU from overheating during the full load. The second method uses some advanced features of Intel and AMD processors to bring the power consumption and CPU temperature down. The Intel processors have inbuilt EIST and C1E advanced features, which basically enable this software to put PC screen or the whole system in Standby mode. The AMD processor comes with AMD’s own cool and quiet technology that reduces energy consumption and CPU temperature.

This software also allows you to manually set the system standby time, screen off time when idle, and to add some programs that you don’t want to stop when the system is in standby mode. Plus, it also shows some important statistics on its interface including reduction in annual spending, power consumption in kWh, and CO2 emissions.

TPFanControl

TPFanControl is yet another free CPU cooling software for Windows. With the use of this software, you can quickly drop down the temperature of any laptop and desktop CPU. In order to reduce the CPU temperature, it increases the CPU fan speed. It also provides a manual option to its users to manually increase the CPU fan speed when needed. In it, you get three modes that affect CPU fan speed and temperature namely BIOS (embedded controller), Smart (TPFancontrol.ini), and Manual. The BIOS option lets the system BIOS adjust fan speed according to the CPU temperature. The Smart option activates TPFanControl drivers which effectively manage CPU temperature and fan speeds. The Manual option lets you manually manage CPU temperature by increasing or decreasing the CPU fan speed.

Besides reducing the CPU temperature, this software can also be used to monitor real-time CPU and GPU temperatures and their fan speeds. Overall, it is another handy CPU temperature controller that you can use with ease.

NoteBook FanControl

NoteBook FanControl is a free open source CPU cooling software for Windows. This software is designed for notebooks of various popular companies like Acer, ASUS, Dell, Fujitsu, HP, Lenovo, etc. Using it, you can monitor as well as control CPU temperature by manually increasing the CPU fan speed of a notebook. Apart from managing the CPU fan speed, it also shows real-time CPU temperature.

To use this software, first, you need to select the exact model and company of your notebook. After selecting the notebook model, you can change the fan speed by selecting the Enable option and dragging the fan speed seek bar towards the right to increase speed (to cool down CPU) or towards the left to decrease fan speed. There is also a Read-only mode that lets you try different configuration without actually instructing the EC to change fan speed. Overall, it is a handy CPU cooling software as it gives you complete control over the CPU fan speed.

ZOTAC FireStorm

ZOTAC FireStorm is the next completely free and easy to use CPU cooling software for Windows. It is mainly a graphics card tweaking utility through which you can monitor and control the fan speed of CPU and Nvidia Graphics card. From its Fan control section, you can view real-time fan speed and manually change fan speed to decrease the CPU temperature. Apart from reducing CPU temperature, you can also vary clock speed, memory clock speed, shader clock speed, and VDDC values from its Clock section.

This software also provides a dedicated Monitoring section from where you can view real-time GPU clock speed, GPU temperature, Fan Speed, etc. Overall, it is a really good CPU cooling software to manage the temperature of both CPU and GPU.
