How to Fix the “CPU Fan Error!” Message

“CPU Error with Fan!” – is being displayed on your monitor, and your computer won’t start.

There’s nothing more annoying than turning on the computer to see an obscure error message that makes it difficult to get some work (or enjoyment) accomplished.

Sometimes, the issue is simple to identify and easy to fix, but more times you’ll need to manually copy-paste the error into Google Search to find out what’s happening.

It’s the error that occurs when you try to use the CPU seen in Motherboards manufactured by ASUS and other Brands is a bit in both of these categories. It is clear what’s causing it to show up however the solution isn’t as simple in certain instances.

Even the CPU cooler is connected and functioning in a proper manner, you could encounter this error.

Don’t worry!

In this article, we’ll review the most common situations that could be the cause of the error, and give some tips and tricks to fix them all.

We’ll also discuss the kinds of situations that a quick fix will not be feasible, and what that can mean for you moving forward.

What Does the “CPU Fan Error” Message Mean?

At a fundamental basis at a very basic level, the error message for CPU fans (CFEM) is the motherboard’s way to inform you that it cannot recognize a cooling device for your CPU.

Furthermore, since running a processor without cooling could be a great method to compromise the integrity that your CPU has, the motherboard stops the computer from starting.

It’s a great safety precaution that your motherboard can use to protect it from overheating.

It is a way to ensure that unaware PC Builders aren’t causing unintentional damage to their equipment.

How to Fix a CPU Fan Error

After you have read and understood why people get the CPU fan error message, you can and resolve these CPU fan issues using the following tips:

In BIOS open and modify the CPU fan settings.If you truly altered the BIOS settings prior to restarting your computer and then reopen the BIOS interface in order to restore the fan elements.

Here are some typical steps you can refer to:
Step 1  Go to the BIOS screen by pressing F2, F12, or Del after restarting your computer.
Step2. Click the Power tab and select Hardware monitor from the pop-up list.
Step3. Select the CPU FAN SPEED option and change it to IGNORED.
Step4. Click on CHASSIS FAN SPEEED and then change it to N/A.
Step5. Select the final option Power Fan Speed and transform it into IGNORED.
Then, typically the computer will not display the error message ever again.
However, if the BIOS settings for the CPU fans have not been altered, don’t be worried. You can proceed to your next section.

  • Verify that the CPU fan is working properly at the right speed
    Now, close your computer properly and then start the host computer to see how the processor fan is operating efficiently and at a proper rate. If it’s running at a ridiculously slow speed it is best to examine carefully to determine the best way to improve the speed.

Device Error

The CPU fan display error message can be demoralizing, particularly even when everything appears working correctly. You’ll be relieved (or sad) to learn that it’s not always your fault.

The unfortunate fact is that all devices fail eventually. It could be tomorrow, in the near future, today or even in five years however, they will fail. When this occurs to a cooling system, it is known to trigger the CPU fan header. There are three primary kinds of cooling (Air, AIO, and Loop). In this article, we’ll provide a very simple observation to make so that you are able to take a shrewd decision when it comes to problems with your device.

  • Air Check to see whether the fan attached to the header of your CPU is working correctly and doesn’t appear to be very slow or meet any resistance.
  • AIO – A bit more difficult, however, you’ll be able to hear the AIO pump start to work, and be accompanied by a distinct water sloshing sound in the initial few seconds of the PC turning on.
  • Loops are applicable to full loops as well as CPU loops, but only. Verify that the water within your loop is moving. It is helpful if you have an instrument to monitor the flow with ease, but if you don’t an easy visual check will suffice.

Pump tip: Your pump will inform that you it’s either on the way out, or has sustained any damage. Pumps (whether in loops or AIOs) often whine when they’re not feeling well. You can observe this in the form of a high-pitched whine. It’s irritating and difficult to spot, but it’s often misinterpreted as a whine from a coil or an PSU however that’s an entirely different matter.

If you notice any of the systems listed below not functioning properly, it’s most likely that your device is in error.
The only way a device is able to cause the processor fan issue is if it is connected directly to the motherboard’s CPU fan header. It is not necessary to look at for any additional devices.

Motherboard Error

After having gone through everything, above, it’s entirely possible that the motherboard or the CPU fan header itself is damaged. If you’re certain there’s nothing going on with your cooling system, It could be the motherboard.

It is best you RMA your motherboard as long as you’re still within the warrantied timeframe before making any repairs. There’s a simple method to overcome this, if you’re not keen on having your computer off for a couple of weeks. Let’s get started.

Update BIOS

The majority of fan issues occur on ASUS and Megatrends are due to BIOS software that is not functioning properly. If you change your BIOS version to the most recent version, you’re good to go.

Set CPU Fan Speed Lower Limit

Is the CPU fan operating at the minimum RPM? A majority of the time, an Asus fan error will give you an indication that the fan is not performing as it should in relation to its RPM.

If you are using NZXT, a Corsair fan with smaller revolution speeds could not be able to identify it.

Make sure to set to the “CPU Fan Speed Low Limit” to 200 RPM within the BIOS configuration.

To alter the speed of your fan’s lower limit Follow these instructions:

  • You can enter BIOS with the F1,F10, or delete key after starting.
  • Go to your Settings for your CPU’s fans by using the Advanced settings. (This section will differ depending on the model of your motherboard.
  • Look for the option that governs the alerts for CPU fan RPM. The default setting will be set to 600 RPM (Revolutions Per Minute).
  • Reduce the default setting from 300 RPM, then the 450 RPM. save the modifications.
  • Open the BIOS and start the system.

Clean the CPU Fan

Dust is the main enemy of computer hardware. If dust accumulates inside, it , it stops fins from rotating at the speed they should.

Clean the CPU’s fans. To do this, shut off the PC , unplug the power cable, then use compressed air in order to blast away the dust.

Try an Alternative Header for the CPU

Modern motherboards feature multiple fan headers , in the event that one doesn’t work. Try connecting the fan to an alternative slot. This may fix the problem with the CPU fan.

Final Thoughts

A CPU’s fan can be an essential element of your PC’s configuration. It makes sure that a perfect temperature is maintained throughout every internal component while your computer is in operation. A variety of issues with the CPU fan could stop your computer from operating correctly. This is why these fixes will be kept in mind when attempting to fix the issue with your hardware.
