How To Set Cpu Fan Speed

A computer adjusts its fan speed according to the load information technology gets. If you are doing some CPU-intensive tasks, your CPU cooler will spin at a college RPM (Rotations Per Minutes). The same goes for your GPU.

However, y'all can command your fan speeds co-ordinate to your needs using third-party applications or tweaking fan settings on your BIOS.

How Does a Estimator Modify the Fan Speed?

First, allow's hash out how a figurer controls its fan speed. Depending on the cables attached, the fans on a desktop PC are continued either to the motherboard or the ability supply. You lot can find iii types of cables that connect the fans to the motherboard/ability supply.

• iii-pin DC fan connector cable connects the fan to your motherboard. Fans connected with this cablevision spins at maximum RPM unless nosotros change the speed from the BIOS.
• 4-pivot Pulse Width Modulation (PWM) is also continued to the motherboard. However, it uses the sense pivot to control the RPM according to the CPU load.
• Molex Fan Connector connects the fan to your PSU (Power Supply Unit). Fans connected with this cable also spin at maximum RPM. Nosotros demand a Molex to iv-pivot PWM hub to control its speed.

How to change fan speeds?

Hither are a few techniques to change/control the fan speeds.

Controls From BIOS

Any piece of hardware fastened to a motherboard will take settings in the BIOS to control information technology. If you have connected the fans to your motherboard, you can easily adjust its speed with the help of the BIOS.

Sometimes, the fans on your estimator will spin at their maximum RPM. This is considering the RPM, by default, is set to maximum on your BIOS (Basic Input/Output system).

• To enter your motherboard'southward BIOS, printing the Del or F12 key chop-chop
  (If you lot practice non know how to enter the BIOS, please refer to the user manual for your laptop/motherboard).
• Once inside the BIOS, utilize the arrow keys to navigate through it.
• Search for a Fan Speed Control option. Again, the option displayed will exist different co-ordinate to the motherboard manufacturer.
  

Some motherboards will take a Smart Fan Mode feature in the BIOS. This feature volition automatically increase or subtract the fan speed co-ordinate to the temperature of your arrangement.

If you want to run the fans at maximum speed all the time, you tin disable this characteristic. In one case you disable the Smart Fan Control, all CPU and arrangement fans will spin at a high RPM.

Some motherboards volition too allow y'all suit the fan curve that enables the user to ready the fan speed according to the temperature.

Fan Controlling Kit

If y'all do not want to open up the application every time you desire to alter the fan speed, then the fan decision-making kit volition be your best friend. Using the equipment, yous can practise this manually by turning a knob.

A fan controlling kit is a physical device that adjusts your CPU and case fans. You can adapt this kit on the front end side of the PC case like any CD/DVD drive. The kit will either have a knob or an LED display to adjust the RPM of your fans according to your need. The equipment will also display the current RPM of all your fans.

One downside to this kit is that these kits cannot command the fans connected with a Molex Fan Connector and the GPU fans.

Third-party software

Tweaking the BIOS setting can be a little risky as in that location is always a chance that your OS may non kick. If you are on a desktop estimator and practise not want to change the BIOS settings, you tin can always use a third-party application. These applications will help you melody the CPU and GPU to go maximum operation with low dissonance.

Please note that y'all cannot control all fans inside your motherboard. You cannot change its speed if the fan is connected to a PSU (Power Supply Unit) through a Molex Fan Connector.

Withal, if the fans are connected to the motherboard, either with 3-pin or 4-pin, these third-party applications can command the fans' speed with a click of a button. Some of the best Fan Control Software are listed below.

• MSI Afterburner (supports any motherboard and graphic card)
• Corsair iQue (Corsair products only)
• FanControl (Simple yet elegant)
• ZOTAC Firestorm (ZOTAC products only)
• Mac Fan Control (For Mac but)

Adjust from Windows settings

This is a simple Windows feature that lets you lot change the fan speed. You lot tin can follow these steps below:

Annotation: But desktop users can access this Window feature to alter the fan speed.

1. Printing the Windows fundamental and open up Command Panel.
   Make sure that the View past option is Large icons on the top right.
   
2. Click on Power Options.
3. Under Choose or customize a power plan, click on Change programme settings.
4. Click on Change Advanced ability settings. A new Power Options dialog box will open.
5. Scroll down to Process power direction and click the "+" icon abreast it.
   
6. Select System Cooling Policy. Then, click the dropdown icon.
7. At present select active from the dropdown menu.
8. Click Apply, then OK.

FAQs

How to Control All Computer Fans Simultaneously?

Y'all can command all reckoner fans simultaneously using a fan hub. It is a junction-type device that connects all the cables from your case fans.

How to Control Fan With Molex Fan Connector?

If you want to control the Molex fans (fans with Molex Fan connector) with the kit, you tin get a cable that has iii ends:

• 1 stop is a four-pivot PWM connector.
• Another one is a Molex connector.
• The last one is connected to the fan.

One cease (Molex Connector) of this cable is attached to the PSU, while the other (the 4-pin PWM) is connected to the motherboard.

Tin I Control Molex Fan without Any Adapters?

Yes, you can lower its speed by providing the fan with a low voltage. A Molex connector has iv pins attached: two footing pins on the center, one pin that provides 5V, and the terminal one providing 12V.

Y'all can rewire the Molex fan connector to a 5V line instead of the 12V, and this will make your fan spin at a lower rate. However, if the fan doesn't spin on 5V, connect it to the 12V line.

Tin can I Convert a three-Pin DC Fan Connector to iv-pin PWM?

If you want to control a 3-pin fan, yous tin can find adapters that convert a 3-pin DC fan connector to 4-pin PWM.
