How to fix cpu fan error in asus motherboard?
Are you facing a CPU fan error on your Asus motherboard? Do you want to troubleshoot this issue and get your PC up and running again?
CPU fan error is a common problem that Asus motherboard users encounter. The CPU fan is critical for the temperature management of the computer system. If the fan isn’t functioning correctly, your PC may overheat and cause permanent damage to the system. However, this issue can usually be solved without the need for professional help.
If you’re experiencing a CPU fan error on your Asus motherboard, don’t fret. In this article, we’ll walk you through the steps to identify and fix the problem. We’ll be exploring the reasons why this error occurs and what you can do to fix it. So, let’s dive into the solutions and get your PC back up and running!

How to fix the CPU fan error in ASUS motherboards?
The CPU fan error in ASUS motherboards can be quite an annoying issue to fix. It usually occurs when the fan of your CPU isn’t connected properly or when there’s a fault in your motherboard. The message that appears on the screen will usually say ‘CPU Fan Error’ or something similar, and this is the motherboard’s way of informing you that it cannot find a CPU cooling device. Luckily, this issue can be quickly resolved by rechecking the connection between your fan and CPU, as well as examining the motherboard for faults.
For those looking to further understand what might be causing their CPU fan error in ASUS motherboards, it’s important to first ensure the fan is attached properly and functioning correctly. Furthermore, make sure that no wires related to the fan are loose or damaged. Lastly and most importantly, test your motherboard for any possible faults by taking off any additional cards and accessories attached to it and then testing them individually with a voltmeter or tester pen if needed. If everything appears normal and still nothing changes, it is likely better to ask a professional technician to have a look at your motherboard as they would be more experienced in fixing these types of problems compared to regular consumers.
How to fix CPU fan error?
When it comes to diagnosing and fixing a CPU fan error, the first step is to check if the fan is rotating at all. This is an obvious yet important step as the root cause of this problem could be that the fan has stopped working completely due to wear and tear over time or due to dirt and dust build up. It’s highly recommended to clean out your CPU fan regularly with pressurized air, as this can help keep it free from dust and debris which can impede its ability to rotate at normal speeds and thus lead to errors.
There are also some other solutions you can consider if cleaning doesn’t help with restoring the optimal rotational speed of your CPU fan. For example, when your computer is running, you can look inside its casing in order to identify any possible obstructions that could trigger an overheating issue—this will require you opening up your PC using protective gear like anti-static gloves. Furthermore, our website provides a detailed guide on how you can clean your PC without compressed air in order to minimize damages.
Make sure the CPU fan is plugged-in properly
Proper CPU fan installation and connection is essential for the proper functioning of any computer. It is important to make sure that the fan is properly plugged into the motherboard’s CPU_FAN header as this allows for better cooling systems that can help prevent a processor from overheating. Additionally, it also helps in reducing unnecessary noise produced due to improper connection of the fan itself.
To make sure your CPU Fan is connected properly you should check the fan connectors on the motherboard. This means checking that the cooler has been correctly mounted and consistently receives liquid flow if it’s an AIO liquid cooler. Failing to plug in or improperly plugging in a CPU fan can lead to overheating, reduced performance, and even damage to internal parts which may cause costly repair bills later on down the line. Taking care of these issues early on can save you a lot of time and money investing yourself in sustaining better system health.
Check if it’s a manufacturing fault
When troubleshooting any mechanical or electrical issue, one of the last considerations should be a manufacturing fault. Although these types of problems are generally not common, they can still occur and should not be disregarded when all other possibilities have been investigated. One way to quickly check for a manufacturing fault is to connect a case fan physically to the CPU Fan Header. Whilst this may provide a temporary solution, it is advised that you do not boot up your system before determining if the fault lies with production.
Other strategies can be used to identify inadequate production quality including visually inspecting parts for signs of poor construction or damage, listening for humming sounds from fans and circuitry, or even measurements such as voltage tests to determine if the components are functioning correctly in a controlled environment. In either case, it’s always important to remember that even high-quality components can sometimes have flaws stemming from the production process and could potentially explain why your system is malfunctioning.
CPU cooler failure
When it comes to keeping your computer running at its best, one of the most important factors is keeping the CPU cool. Over time, heat can damage your hardware, leading to problems like PC slowdowns and crashes.
One of the reasons behind the CPU Fan Error might be the failure of the CPU cooling system. There are numerous reasons why a CPU cooler can stop working, including oxidation brought on by liquid damage, a failed AIO pump, or a cooling fan that stops spinning on its own.
Depending on the cause of the failure, you might need to replace the fan altogether or just have it serviced. However, if the problem is with an AIO liquid cooler, you may need to get in touch with the manufacturer to see if the part is still covered by warranty.
CPU fan dead on arrival

It is not an uncommon occurrence for a CPU cooler to arrive dead on arrival (DOA). If this is the case with your PC, you should immediately contact the vendor from which you purchased the product and request a Return Merchandise Authorization (RMA). To confirm that the cooler indeed is dead, try connecting a different fan to the CPU_FAN header of your computer and make sure it boots successfully. However, even if the replacement fan works fine, it’s highly recommended not to use it in this setup since it will leave your CPU without proper cooling.
To avoid issues such as these you might consider doing some research regarding aftermarket or third-party CPU coolers before buying anything as there are many options available online with good reviews. This can save you money while also potentially improving cooling performance when compared to stock parts. Furthermore, check if there is a warranty offered on such products so should any issue arise during use; you’ll be able to take advantage of that coverage. It’s always better to invest some time into researching options before making any purchases in order to make sure that everything works properly right out of the box and stays running well over time too.
