How to fix the noises from the Lenovo idea pad 320 fans

I. Switch on the machine

When having a machine that makes some noises with the fan and you would like to check on the central problem causing the noises, it is good that you switch on the machine for the checkups. Switching on the machine helps an individual be keen on the parts within the fan making noise and check on the process consuming much power forcing the fan to run at high speed.

ii. Kill all the active processes in the background

After starting the machine, check on the ongoing processes at the taskbar to check on the machine’s running and consuming power. Most of the time, you can be using the machine with light activities, but at the background level, some heavy activities consume much power such that it can consume much power from the laptop.

Therefore, if the machine consumes much power, there will be a high chance of overheating that later makes the fan run at a higher speed causing the noises; therefore, if you hear such noises check on terminating the processes to reduce the noises.

iii. Update the available software for management of power

After killing the processes that consume much power from the machine, consider checking the software that works by helping the power management in the machine to reduce the power consumption rate. If you lack the software, you can download it so that it helps you when the machines consume a lot of power by managing it.

iv. Update the BIOS

Update the BIOS

Check on the BIOS updates of the laptop and follow the necessary instructions to carry out the task. First, ensure you plug the laptop into the power and that the charger is in the correct position for charging. Close all the running programs in the machine and ensure all settings are at default to do the updates.

v. Cleaning of the dirty components

If you have a laptop that keeps on making noise, mainly with the running fan, consider checking for the dirty parts and cleaning them. With cleaning, choose to use specific detergents that cannot cause damage to the parts.

vi. Replace the faulty parts that cause the noises

When you have any part in the machine or the fan causing the noise, consider checking on the specific part and identifying its problem. Some parts have minor damages that you can quickly check on them and fix immediately.

vii. Check CPU usage

When checking the CPU usage, consider opening the task manager and checking if an intensive program is running in the background that stresses out the CPU.

viii. Dirty air vents in the fan

Dirty air vents in the fan

Dirty air vents block the flow of air to the laptop and out of the laptop. The dirty particles then cause the fan to strain while compelling air at high speed.  When the air is entering the fan, sometimes it can contain some air particles that can accumulate in the air vents that later block the flow of air in and out of the vents. Therefore, when you have the fan, consider checking the air vents regularly to remove the dust and other debris that accumulates into it, blocking the flow of air.

ix. Heavy processes are running in the background

In some cases, the laptop is working without the user knowing some processes are running in the background.  Some processes in the background consume much of the power that can cause the laptop to produce a lot of heat which later causes the fun to run at higher speeds to compel air for cooling the machine. When the fan runs at such high speed, it will later cause the production of some noises.

x. Overheating

How to prevent overheating

During normal computer operations, the machine tends to produce heat. The production of heat is because there is the use of power that causes the machine to run. When a computer overheats, it causes the fan to strain while compelling air to cool the machine, producing some noise. Sometimes the computer experiences overheating problems since the fan air vents block due to the accumulation of dust at the vents, preventing heat dissipation outside the fan and causing overheating.

xi. Issues with the bearing

When the bearing has some issues with it, such that it is broken or has some defaults, it will fail to work correctly in the machine. And we all know that if the bearing has faults, then the fan will be having some issues too. Therefore, when you have a faulty bearing at your place, the fan will make noises since it lacks some assistance when running.

xii. Bad motor

A motor in a laptop provides power to the machine to support some more activities to run smoothly. When the motor is wrong, it means either there is less transmission of power to the fan causing the noise since the fan strains to work correctly, or maybe there is the excess transfer of power to the fan, causing it to run at a higher speed causing the noise at some point. Therefore, if you are having such issues consider replacing the motor immediately to reduce the noises.
