Whenever your CPU or motherboard temperature rises, your computer fans start rotating faster. Depending on the design and number of fans, they can get very loud.
To fix this issue,limit the system temperaturethrough various means. The quickest way is toclose all unnecessary processesthat are overusing your system resources. You should alsoclean your fans and the PCif they are very dusty.
If your fans are loud from the get-go,lower their speed through the BIOS. If nothing works,replace the fans with quieter modelsorupgrade your cooling systemaltogether.
Here, I’ll mainly be talking about PC case fans. If yourCPU cooler fanor any other PC components like radiators, GPU or PSUs are loud as well, you may need different fixes. Regardless, let’s get right into the proper fixes.
Check Fan Speed
The first thing you should do when your computer fans get too loud is toget to the BIOS(press the BIOS key on startup) andcheck the computer fan speed.Check the speed of all chassis and CPU fans.
The fan speed should ideally be the minimum at low CPU/motherboard temp (less than 40°C). Then it should gradually increase until it is the max at high temperatures (more than 75-80°C).
If the earlier speed itself is high, then your fans will be noisy even when the CPU/motherboard has a stable temperature.
In such cases,lower the speedto have aquieter system on a low load or idle state. you may also check our dedicated guides on checking and controlling fan speed for some common motherboards:
If you don’t want to get to the BIOS, several free third-partyPC fan control appsare also available on the internet.
Monitor System Temperature and Lower Resource Usage
If your system has a good fan speed curve, it’s likely that your system temperature stays high.
In such cases, the fan will rotate at a higher speed and produce much noise. To maintain a safe temperature, lower the resource usage using the following steps:
Clean the Fans and PC
If your fans are very dirty, they won’t allow proper airflow inside the case and may even increase the total thermal insulation of the PC case.
In such cases, the fans will move at their highest speed to compensate for the rising computer temperature.
You shouldregularlyclean the computer fansto prevent any such issues.Open the left side panel of the PC caseandspray the case fan with compressed airto clean it.
You may need to remove additional panels to blow the air from both sides of the fans.
It’s also better toclean dust from other PC componentsto maintain good airflow and cool down your system.
Sometimes a loosely fitted case fan may generate some noise, so ensure all your fans are tightly intact.
Upgrade Cooling System
Nowadays, you’ll find many fans that providegood airflow while being very quiet. If you may’t limit the noise produced by your original fans,replace them with quieter ones.
You canbrowse the internet or check out PC-building forumsfor more information. Don’t just blindly trust the product specifications, butcheck actual user reviewsbefore buying any new fans.
Another thing you may do to to maintain the internal temperature is toupgrade your entire cooling systemaltogether. For that,
