Laptop Fan constantly runnin with irritatin sound

[Yuwan]

Hello

 When I turn on the laptop, the fan turns on. The fan is constantly running and the noise is very loud. There is no process on the task manager which is consuming the CPU HEAVILY and it is not hot too. And I've updated the BIOS TOO.

Sometimes it goes off after some time and then starts again.

Please suggest a solution asap

Welcome to the HP Forums, this is a great location to get assistance! I read your post and see that your laptop fan is too loud and running constantly. I would like to help you resolve this issue. 

However, I will need a few details to provide an accurate solution,

When did this issue start?

Did you do any changes to the notebook?

Meanwhile

Remove dust and lint by cleaning vents

Most notebook computers have vents located around the case to allow air to flow through the case. If these vents become clogged, or if heat-generating parts become covered with dust, the fan cannot cool the components properly, because the laptop is hot and overheating becomes a problem. Lint and dust accumulation prevents air from flowing around the cooling fan blades and causes the fan to work harder and the laptop to get hot. If there is dust in the vents, you should clean the laptop by blowing out the dust from around the fan and heat shield. This prevents dust from accumulating.

It is not necessary to open the notebook (laptop) to clean out the dust with the canned, compressed air.

The following graphics show the dust accumulation on the inside of the laptop, but dust around the fans and heat shield of the laptop can be cleaned without opening the computer.

Use a can of compressed air (a vacuum cleaner on blow function or a hair dryer in cool air mode can also be used, though compressed air is better suited for this task) to remove dust from the laptop vents and prevent overheating. Removing the dust increases the air flow to improve cooling and allows the fan to run quieter.

The cooling vents are located in various places depending on the laptop model. You can identify the vents by looking for the copper or black fins inside the vents.

   NOTE:

Be sure to find and clean all the vents on your laptop with the compressed air . Your particular laptop might have vents on the side, the back, or the bottom. Some newer laptops might not have any vents at all.

You should blow the compressed air into the vents on your laptop, and into other openings such as the fan intake vent to help keep the air circulating and prevent dust from accumulating on components.

By taking this action periodically as a preventive measure, you can greatly reduce the possibility of component damage and prevent the slowdown of the notebook's performance.

The Laptop is 9 months old. I didn't do any changes except the regular Windows and Driver updates using HP SUPPORT Assistant

This issue started about a week ago.

And this cleaning thing, can I do it myselves?

There are no side vents in this model (PAVILION 15 CC502NE) and is it safe to unscrew the back panel and clean the fan?

@Yuwan,

I'm the Jeet_Singh & I'm at your service.

As I understand the fan is constantly running and making a noise, I would suggest you follow this link: HP Notebook PCs - Fan is Noisy and Spins Constantly, PC is Warmer than Normal

Updating your Notebook computer BIOS (skip this step if you have already performed).

Keeping notebook air vents clear and clean

Increasing the efficiency of the notebook to reduce heat

Using Windows Task Manager to identify corrupt processes

Selecting power saves settings to shut off your computer when it is not in use

Answering to the speedfan running? HP does not recommend to use Third party measuring apps as they are not tested by HP and may not be accurate. 

Next thing, I would suggest here is to run an extensive system test on the computer from F2(Please capture the failure ID for further assistance).

Please perform all these steps patiently as it is critical to resolving the issue. The trick is to remain patient, please. Please note that I am not overloading you with a lot of troubleshootingsteps.

Instead, just like you, I am eager to ensure that the problem gets resolved. So I am providing you with more resources and information at your disposal to deal with the situation better.
