A Central Processing Unit (CPU) is a component that performs calculations and operations on data. It is the main component of a computer system and is responsible for running programs. The CPU is housed in a chip on the motherboard and consists of multiple cores, which can handle various tasks simultaneously.
The function of the CPU is to carry out the instructions in a program. It reads data from storage, performs calculations, and writes the results back to storage. Due to constant working, CPUs develop many issues. One of these issues is CPU noise. Let’s discuss the potential causes and remediation.
Why Is My CPU Making A Noise?
The CPU makes noises due to overheating, loose screws, and fan failure. Excessive heat buildup is the most common cause of noise in a CPU. The heat generated by the CPU can be managed through proper cooling systems, like air or liquid cooling systems.
Overeating: Overheating is one of the biggest enemy of your computer system. Overheating damages the components; as a result, the component fails. Overheating components also require constant cooling, and fans provide that cooling in PCs. That is why you hear loud fan noises coming from your computer system constantly.
Fan Dust: The CPU often makes noises when the fan or cooler is either damaged or not working properly. If the fan blades become clogged with dust, they will fail to spin smoothly. These will be friction between fan blades which will lead to frustrating fan noise.
Loose Screws: Screws are also an essential components that hold your fans, motherboard and other hardware with PC case. Loose screws can also cause rattling noises if they contact the CPU or other components. Here are some potential methods to remediate the CPU noise for good.
Low Thermal Paste: Your CPU will heat up if your thermal paste is dried out, which will force your CPU fans to run constantly and make noise. As a result your fan will make noise. Try to apply paste periodically to avoid this issue.
Rusty Cable Connections: All computer fans are connected to motherboard via cables. These cables often get old an rusty. Old rusty cable connections will lead to less current supply to the CPU fan. As a result, it will produce a whining noise.
Clean CPU Cooling Fan
Your motherboard and computer case has several fans and cooling systems to remove excess heat from the CPU. The CPU also has its separate fan to do this job. When this fan
Take off the side panel of your computer case and use a compressed air canister to blow out all the dirt, dust, and debris that has accumulated inside. You can also use a small brush to clean the fan blades and then reattach the fan.
- First, turn off your PC and remove all power cords from it.
- Now Take off the side panel carefully and place it on the side.
- Use a soft bristle brush to clean the CPU fan gently.
- Now use an air blower to remove dust from the fan’s surface.
Your CPU is connected to the CPU socket, and on the top of that socket, there is a latch screw. This latch screw holds the CPU in place. Over time, these screws become loose, which can cause rattling noises. To fix this, you must tighten the screws properly and ensure no gap between the screw heads and the CPU.
- Open your PC Case and locate the CPU fan.
- Take a screwdriver and make sure that the screws near your CPU fan are tightened properly.
Check CPU Fan Connections
If your CPU fan is not getting the proper voltage and current, you can hear rattling noises from it. You need to open your PC case and locate the fan cable to check and fix the connection issue. Ensure the cables are properly connected on both ends and that all pins work fine.
You can also use an ammeter to locate the fault. If you still can’t figure out what’s wrong, you can replace the wire that connects to the fan or the fan itself.
Apply Thermal Paste
The main reason for your CPU making noise is overheating. To prevent this from happening, you need to apply thermal paste between the CPU and its heat sink. This will ensure that there is proper thermal conductivity, and it will also help spread the heat more evenly.
- To apply thermal paste, take a pea-sized amount, place it on the CPU, and then spread it evenly.
- Ensure that the thermal paste is not in contact with any pins or components, as this can cause damage.
- Finally, attach the heat sink to the CPU and power your PC.
- These are some of the potential causes and remediation for CPU noise.
Use Water cooling
If you have to change the fans constantly and still hear CPU noises, you might consider using a cooling water system for your CPU. Water cooling systems provide more efficient cooling than air-based systems and are quieter. These coolers are often used in gaming and high end PCs. As they require instant cooling.
Also, make sure you use your PC’s right water cooling system. Many types of water cooling systems are available, and it is important to pick the right one for your PC. Don’t use this cooling system if your PC doesn’t support it.
Is It Normal For CPU To Make Noise?
Noise coming from the CPU is not normal and should be addressed immediately. Noise can signal a problem with the cooling system, which could get worse if not fixed. If you hear any noise from your CPU, it is best to take preventative measures immediately. Keeping your PC clean, using a cooling system that is the right size and works well, and securing all parts properly can help reduce noise.
It is not normal for your CPU to make noises. If you hear any unusual sounds from the CPU, take steps to identify and address the issue before it worsens. By taking proactive measures, you can ensure that your CPU will operate correctly and efficiently. Leaving your CPU unattended may increase the noise issues and ultimately lead to component damage.
Noise coming from your CPU is not normal and should be addressed immediately. This noise can signify an issue with the cooling system, and it is best to take preventative measures immediately. Ensure that your PC is clean and its parts are properly secured, use a cooling system that is the right size and works well, and apply the thermal paste for better cooling.
