How To Change CPU Fan Speed Without Bios? [Easy Guide]

How to change CPU fan speed without BIOS? To do that, you can use fan control software that enables you to change the settings.

This requires you to download and install an application from the Internet. We’ll share more about this in the article.

Another option for adjusting fan speed is to use an external fan control to adjust speeds manually. But if you have an older fan, it may not be suitable to change speeds this way.

Adjusting fan speeds is an ideal way to improve PC performance because it makes the regulation of airflow more efficient depending on what the system is getting used for.

We’ll divide the article into a series of questions covering how to adjust the speeds of CPU fans without using the BIOS. Once you’ve read it, you’ll find it quick and easy to adjust speeds with no BIOS use.

Let’s dive in!

Can You Increase CPU Fan Speed?

Yes, you can do this. Fan control software, an external fan controller, or the BIOS can get used for this purpose.

When you change the fan speed, it’s an immediate change, regardless of the fan type. You can either set it to increase or decrease.

Increasing speeds might seem like an unusual choice. But if your computer is in a warm location or getting intense use, then it’s a worthwhile decision.

What RPM Should My CPU Fan Be?

Investigating how to change fan speed separate from the BIOS may lead you to discussions about RPM. This stands for Revolutions Per Minute and relates to how fast your fans spin in a minute.

70% of your CPU’s RPM capacity is an ideal standard to aim for, but if the temperature is at 70 degrees Celsius or higher, 100% will be better.

Generally, 50% of your CPU’s RPM capacity is acceptable if the temperature ranges between 50-55 degrees Celsius.

When adjusting RPM speeds, they can vary between a minimum and maximum threshold.

How Do I Change My CPU Fan Speed Manually?

There are several ways to adjust the fan speed. Examples include using specific tools such as SpeedFan, EasyTune 5, and Argus Monitor.

You can select the speed you’d like your computer to have in each software package and then apply the changes instantly.

Software solutions include the application we listed above, plus the BIOS, and hardware solutions include external fan controllers.

Speed can get controlled because sometimes the computer needs manual fan speed regulation. It depends on the purpose of the system and how customizable it is.

This depends on the level of expertise of the user. A gamer or power user will see extra benefits from fan control than an everyday user.

How Can I Control Fan Speed Without Using BIOS?

Using fan control software like SpeedFan, you can change the fan speed without BIOS.

This is the simplest way to adjust the speed with no BIOS use, but sometimes the software doesn’t recognise fans properly. Other options include Corsair Link and Notebook FanControl.

If these don’t work, you can buy an external fan controller. But if you do this, we recommend checking it’s compatible with your fan.

There can be specific fan controllers depending on your PC’s fans, so it’s worth checking this in advance.

In addition, here’s a useful video on how to use “Speedfan” properly.

How Do I Control Fan Speeds In My Case?

Changing CPU fan speed without BIOS can get achieved in three ways. The BIOS, third-party applications, and fan controllers.

The location of the fans inside the computer case doesn’t affect anything based on what I’ve seen.

But if you’re concerned about your computer’s case obstructing airflow, you can turn it off and use compressed air to clean out any dust. You can also check to make sure none of the vents get blocked.

Can I Change The CPU Fan Speed Without BIOS?

Yes, you can. You can use any of the methods we’ve mentioned in this article. No method is better than another, but the software solutions are faster to install.

If you need to change the fan speed fast, then using a software such as SpeedFan or MSI Afterburner is most appropriate if you can’t access the BIOS, or it doesn’t support changing the speed.

How To Change The CPU Fan Speed Without BIOS?

You can install a hardware-based fan controller or third-party software such as “SpeedFan”. It depends on how modern your computer is and what solutions your fan supports.

We recommend finding out whether any CPU fans you’d like to adjust the speeds of are compatible with your preferred methods.

If you’re going to use a hardware solution like a fan controller, you should:

  1. Purchase a compatible controller.
  2. Connect the fans to the controller instead of the PSU or motherboard.
  3. Use physical dials or a touchscreen on the controller to adjust the speeds.
  4. Alternatively, use downloadable software provided by the manufacturer of the controller.

What Causes Computer Fans To Speed Up?

When your computer has a misconfigured fan controller, it can cause the fan to speed up unexpectedly.

But the most frequent trigger is either high temperatures within the computer case or intense demand placed on the CPU.

This can come from using complex software like photo editors, coding programs, and complex video games.

More specifically, what happens is that RPM increases to compensate for the extra cooling that’s required. This means the speed of your fans will increase in relation to the CPU temperature.

User-friendly fan controls can help you control this, but automatic fan control is the most common arrangement.

What Causes A Computer Fan To Run Loud?

If your computer fan runs loud, there are a few common causes. Dirt and dust inside the fans are the most likely culprit.

It can cause damage to the bearings of the fan, which can make it emit noise. This is why it’s best to use compressed air, as we suggested above.

But if you don’t have access to a can of compressed air, you can use a vacuum cleaner or a damp cloth.

What Is A Good CPU Fan Speed?

When you control the speed of your fan, you’ll be deciding the minimum and maximum RPM you want the CPU to operate at. Some good benchmarks are 3,500RPM to 4,000RPM.

But these get determined by the CPU itself, so it requires good judgement to decide how to implement speed control.

Some general guidelines that might help you are that you can set the speed at roughly 50-70% of the maximum number during everyday computer use. For anything more complicated, 100% is preferable.

What Causes Computer Fans To Run All The Time?

If you’ve checked the fan control tab and speed control settings, you may notice the CPU fans running constantly.

If this happens, I’ve found it almost always relates to a faulty temperature sensor or an issue with the heatsink. In this case, you can monitor the temperature and change the speed to see what happens.

If the fans still don’t stop running, you’ll need to have your computer assessed by a professional.

How To Control CPU And System Fan Speed?

The most convenient way to do this is through using the BIOS, but if this is not possible, you can do it using third-party software or fan control hardware.

Be careful not to set the CPU cooler fan to a speed which is too low, or it will overheat quickly. You can avoid this by researching the ideal speeds for your CPU based on how you’ll be using the computer.

How Do I Know My CPU Fan Is Working Properly?

If you want to know whether your fan is working appropriately, you can listen to them and inspect them.

If your computer is not using demanding software like video games, the fans will be very quiet. This is because they’re not in use.

But if you use software which places a higher demand on CPU resources, more noise will get emitted, and you can judge if it’s working correctly.
