The need to change the rotational speed of case fans or coolers on a processor or video card can arise in many cases. This is especially true in the summer, when the components of a computer or laptop begin to overheat due to elevated temperatures. By default, the rotation speed rarely exceeds 50-70% of the power and is regulated by the basic input / output system of the motherboard (BIOS) with increasing temperatures of the processor or video card. However, with increasing fan speeds, the noise level accordingly increases, which may be important when watching movies or listening to videos. How to increase the speed of rotation of the cooler? To do this, you can use software, drivers, or the built-in input-output system on the motherboard (BIOS).
Why is it necessary
In order to regulate the power supplied to the fans, it is possible to use several methods. Each of them has its advantages and disadvantages. Without user intervention, the speed of rotation of the coolers is determined by the motherboard, taking into account the performance of each of the components.
Based on the settings that the user indicates in the BIOS, regulation occurs after a change in temperature. Most cooling fans are connected to a 3-pin or 4-pin connector. There are also unregulated cooling systems that are attached to the Molex connector during installation.
How to increase the speed of rotation of the cooler? The number of revolutions per second is determined by the supplied voltage to the cooler device or by regulating the resistance. When attaching a cooler to the corresponding connector on the motherboard, it is possible to change the rotation speed.
However, even taking into account the system of automatic speed control (coolers with regulation), errors in the system may occur, leading to excessive acceleration or deceleration of the rotation of the blades. In this case, the temperature or the noise emitted increases accordingly.
Adjustment methods
There are several ways to fix errors. It is possible to use one of the following ways:
- Adjust the rotation speed in the base system input-output system of the motherboard (BIOS). This method is associated with certain inconveniences, due to the need to restart the device and enter the BIOS. Thus, if necessary, in a short time to increase the speed of rotation of this method becomes unjustified.
- How to change the rotation speed of the cooler? There is also a large amount of software that can speed up or slow down the speed of rotation of the blades. These include SpeedFun, Msi Afterburner, OverDrive and other programs.
- The most expensive way is to buy reobas with the addition of turntables. In this case, you can adjust the rotation speed by rotating the built-in controls in real time, each of which is responsible for a specific fan.
Which of the ways to use it is up to the user to decide. However, the most universal and affordable is the use of software.
Work with BiosBIOS
Most modern motherboards have the function of monitoring and controlling the speed of air cooling systems. In most cases, this is controlled by using the drivers that come with the device. If there are any and proper installation through the BIOS, it is possible to adjust the rotation speed of the cooler blades.
How to increase the speed of rotation of the cooler on a laptop or computer
The method is universal for all electronic computers on which air cooling systems are installed. In order to change the rotation speed, you need:
- Restart the system and enter the BIOS shell. Keys or combinations thereof depend on the motherboard manufacturer.
- Go to the Power section, find the Hardware Monitor tab.
- In the item “CPU Min. Fan speed (%) ”adjust the cooler rotation speed as a percentage.
- Perform the same adjustment with the rest of the items.
- Then save the changes and exit the BIOS under Exit.
Speed Adjustment Software
If it is impossible to work with the BIOS I / O environment or if the necessary items in the section are not available, you can use software that is designed to control the air cooling system.
How to increase the speed of rotation of the cooler on the processor? To do this, you can use the following software:
- SpeedFan
- AMD OverDrive;
- Riva Tunes.
You can download any of them from the manufacturer’s website. After installation, you can proceed with the adjustment.
Cooling system management with SpeedFan
How to increase cooler rotation speed with SpeedFan? The program is completely free and allows you to adjust the speed of rotation of the cooler on both a laptop and a laptop computer. To increase the cooler rotation speed using SpeedFan, you need:
- Download and install this program on the device. The program does not take up much disk space, which may be an advantage for older laptops;
- Initially, the program language is English. To change it, you need to go to the Configure tab, then in the Option section, and in the "Language" section, select the desired one.
- Then you need to go to the "Performance" tab, which shows the current temperatures of the processor, hard drive and other parts. On this screen, you can set the rotation speed of the cooler using the text field Pwm1.
- For automatic adjustment in the "Configuration" section, it is possible to set the minimum temperature that the device will try to maintain.
Features for labeling various fans in SpeedFan
How to change the rotation speed of the processor cooler? On laptop computers, the program can adjust the rotation speed of several connected fans, each of which is connected to a separate connector. These include:
- SysFan (Fan1) - this parameter indicates the speed of rotation of the cooler, which is connected to the SysFan connector on the system board. Fans of a discrete air cooling system that are installed on the north bridge or any other can be connected to this connector.
- CPU0 Fan - this item corresponds to the processor cooler rotation speed.
- PWR Fan - the section is responsible for the rotation speed of either the cooling system of the power supply, or the fan that is connected to this socket on the motherboard.
- CPU1 Fan - the section is designed for dual-processor, server motherboards and corresponds to the cooler of the second computing unit.
How to increase or decrease the rotation speed of coolers with AMD OverDrive
The software is only suitable for air cooling systems that work in conjunction with AMD hardware. This utility is completely free and allows you to overclock the hardware. In this case, the temperature increases significantly, therefore, it is necessary to increase the efficiency of the cooling system accordingly. In order to increase the rotation speed in the utility, you will need:
- Open the application and in the main open the Performance Control tab. In most versions, the version is in the upper left part of the interface.
- Go to the Fan Control section.
- Switch the fan speed to manual mode, then use the sliders to adjust. Thus, you can increase or decrease the speed of revolutions, providing a lower temperature or noise level.
Riva tunes
This utility is suitable for owners of a system based on a processor from Intel. Compared to AMD, OverDrive has a simpler interface. However, the principle remains the same. It is possible to adjust the rotation speed by first selecting one of the devices in the selection window on the main application screen.
Changing the speed of the SVO speed of the video card
How to increase the cooler rotation speed on a video card? For video adapters, it is possible to change the rotational speed of the blades of the cooling system using a large number of software. So, on Radeon video cards it is possible to change the speed of the cooler in the main screen of the hardware management system. Depending on the architecture and publication, this action is significantly different. For video adapters of the 6th version, AMD Catalyst Control Center software is suitable, which must be installed for the correct operation of the hardware. The fan speed is adjusted in the GPU Overdrive column. And first, you need to enable the built-in overclocking ability, then allow manual control of the fans to the user. Then it is possible to manually adjust the rotation speed of the video card cooling system using the built-in slider. In this way, adjustments can be made quickly.
For owners of graphics cards from AMD on the architecture of Graphics Core Next comes updated software called Adrenaline. In it, the rotation speed is also adjustable in the Overdrive section. It is also possible to conduct a comprehensive overclocking of the video adapter.
In addition, it is possible to use third-party software. A utility for capturing images from the MSI Afterburner screen is suitable for this. When starting this program, it is possible to adjust the rotation speed using the Fan Speed slider. Also in this program it is possible to adjust the rotation speed curve and set the temperature limits at which the corresponding speed graph will be set.
Nvidia graphic card holders can increase the speed of the cooler using the Nvidia Inspector utility. This program, in addition to the fan speed, allows you to adjust many items that are responsible for the operation of the system. Thus, it is possible to carry out a comprehensive overclock, obtain performance data, change the core power and driver profiles. In addition, you can set the profiles of the video adapter, depending on the running software. This can be useful at different load levels, depending on the application, when the automatic control system does not cope with the task.
