How do I control the speed on my Corsair PSU fan?

Controlling the speed of your Corsair power supply unit (PSU) fan depends on the model of PSU you are using. Generally speaking, Corsair offers two types of fan control for their PSU fans; fan control built into the PSU itself, and fan control enabled with a fan control software from Corsair, such as CORSAIR LINK™.

If your Corsair PSU has fan control built into the unit, it can usually be accessed by a switch on the back of the PSU. This switch will either be labeled with a fan speed (such as Low, Medium, High, Max) or a percentage (100%, 50%, 25%, etc.


If your Corsair PSU has fan control enabled with Corsair Link, you can adjust and monitor the fan speed from the Corsair LINK software. To do this, launch Corsair LINK and select the power supply from the list of devices.

Select “Fan Control” from the list of options, then select “Automatic” or “Manual” Mode. In Manual Mode, you can enter a specific fan speed, or click “Silent Mode” to set the fan speed to its minimum rate.

Additionally, if your Corsair PSU has the ability to connect an additional fan, you might be able to control the fan speed using a dedicated fan controller. This type of controller allows you to control the fan speed by adjusting a knob or switch, rather than using software.

No matter what type of fan control your Corsair PSU has, it is important to remember that fan speed should be set depending on the heat output of your system. In other words, if your system gets too hot, you should consider increasing the fan speed to prevent overheating.

On the other hand, if your system is running cool, you can reduce the fan speed for more optimal noise management.

How do I lower my PSU fan speed?

The first is to look for a fan control switch on the back of the power supply. Some power supplies have a dedicated switch that lets you toggle the fan speed down. If your power supply does not have this switch, then the second option is to use a manual fan speed controller.

Manual fan speed controllers come in hardware form and can be connected to your PSU via the 3 or 4 pin connectors. The manual fan speed controller will give you better control over the fan speed and allow you to adjust it to the lowest safe setting.

Finally, you could also install software to control fan speed. Software such as SpeedFan or MSI Afterburner can be used to set fan speeds and allow you to adjust the PSU fan speed to your liking. Whichever method you choose, make sure to take precautions to protect your components from overheating.

Can you control fan speed with Corsair Link?

Yes, you can control fan speed with Corsair Link, which is software that helps monitor, customize and optimize your Corsair products. The software provides control over a range of settings, including fan speeds.

Basically, it allows you to select the fan speed of your fans and the temperature that you want them to run at. The software’s build-in fan control settings use “target temperatures” to allow the fans to ramp up and down as the temperature changes.

This can be useful for keeping your system running cool, or for improving noise levels. Additionally, some products, such as the Corsair LL series RGB fans, can be controlled directly in the Corsair Link program, allowing for optimization of speed and brightness for your system.

Finally, Corsair Link also allows for easy control of custom fan curves. This lets you manually adjust fan speeds depending on the temperature that the computer is experiencing.

What software can control Corsair fans?

Corsair fans can be controlled using the company’s proprietary software, iCUE. iCUE runs on both Windows and Mac operating systems and allows users to control their Corsair fan speeds, customize the RGB lighting on compatible products, monitor system temperature and voltage levels, as well as integrate with compatible games and applications.

With iCUE, users can set up customized fan curves or customize synchronized lighting effects for all compatible Corsair products. Additionally, users can also monitor and log fan speeds and system temperatures to identify any unusual readings.

Can PSU fan be controlled?

Yes, PSU fan can be controlled. This can be done through fan control software for the computer. This software will allow you to control the speed of the fan, allowing it to run at a lower speed to reduce noise or a higher speed for better cooling.

In addition to using fan control software, you can also buy a fan controller that allows you to control the fan from inside the computer case. This can be done by adjusting knobs or switches which are dedicated to controlling different temperatures.

By controlling the fan speed in this way you can ensure that the PSU fan is running at the correct speed for your system, helping to keep your components cool and running smoothly.

How do you measure fan RPM?

The most common way to measure fan RPM is using either a non-contact tachometer or a fan RPM meter. A non-contact tachometer uses a laser or an LED light to measure the RPM of a fan. The light beam is aimed at the rotating component and the reflection, rebounded from the surface, is interpreted by the tachometer.

A fan RPM meter, on the other hand, provides more accurate readings due to the dynamic calculation of the fan’s rotational speed. It operates by electro-magnetically registering the rotation activates multiple times per second which then determines the RPM.

These types of monitors provide feedback of the fan speed in real time. Furthermore, if both the fan and RPM meter are equipped with a communication module, this data can be wirelessly transmitted to another device for even further analysis.

Should a PSU fan run all the time?

Generally speaking, the answer is yes but there are some exceptions that should be taken into account. A PSU fan should always run if the computer is in an environment where the temperature can reach up to and around 35-40 degrees Celsius.

This is because the fan is designed to help cool the internal components of the PSU and prevent it from overheating. However, in an environment with temperatures below 30 degrees Celsius, the fan could be allowed to turn off when not in use, as the risk of the PSU overheating is lower.

Additionally, it is important to check with the manufacturer of the PSU to make sure that the fan is set up correctly and running at the appropriate speed. Finally, if the PSU is older or has been in use for a longer period of time, it may be beneficial to replace the fan as it may be expired or worn, as a worn fan may not be able to move the air required to keep the PSU cool.

Can you control Corsair RGB fans?

Yes, you can easily control Corsair RGB fans. Using their iCUE software, you can customize the RGB lighting, fan speed, and other settings for most RGB fans from Corsair. On top of this, you can sync up your color scheme and lighting effects with other compatible Corsair components like their keyboard, mouse and case.

In addition, it is also possible to access the settings from your smartphone with the iCUE mobile app, allowing you to control your RGB cooling fans from any place.
