Hi Shekhar,

If you feel laptop's fan is not able to cool down your laptop, you can try the below fixes to solve the heating issue.

Fix 1. Buy A Laptop Cooler
Due to their nature, size and increasing amounts of power; laptops seem to just get hotter and hotter. As a rule, my old laptops would generally go for a year without getting too hot. Now they’re so small and powerful that a laptop cooler is pretty much a necessity from day one.
A laptop/notebook cooler, cooler pad or chill mat is an accessory for laptop computers that helps reduce their operating temperature, which is normally used when the laptop is unable to sufficiently cool itself.

Laptop coolers can alleviate this issue by artificially increasing airflow to your laptop's critical components. Most laptop cooling pads accomplish this with powerful fans that push a constant stream of cool air through your system, ensuring that it remains as cool as possible.

Cooling pads like Cooler Master's SF-17, the Thermaltake Massive TM and the Gear Head CFS8800BLK offer features like height adjustment, temperature sensors and USB hubs to make using your laptop easy and comfortable.

Fix 2. Kill Your Processes
The heat generated by the CPU is generally the main heat source within a laptop, and non-vital background processes only serve to make this worse.
You can manually configure what starts up in Windows using the Microsoft System Configuration Utility.
Hit Start, find Run (you may need to search for it, depending on your particular version of Windows) and type in msconfig and click OK.

Navigate to the Startup tab and simply toggle the items you’d like to run when your computer first boots. Many update managers and system tray processes (like Quicktime, Java Update Scheduler, etc) are completely useless and simply sit there wasting your precious resources.

Fix 3. Clean your Laptop
Your laptop’s number one enemy is dust, so removing this dust not only cleans and safeguards your machine but also increases airflow which in turn will boost your fan’s efficiency. I wouldn’t recommend doing this if you’re not 100% sure what your doing.

Fix 4. Check for dust in fan
If the issue is with dust in the fan, I would recommend you to use the app HWMonitor to check the temperatures on your PC. Link for that app is :

Fix 5. Ensure Proper Ventilation
Put the laptop in a location where it can properly ventilate itself. Don’t push the case up against a wall so that its vents become blocked or leave it near a radiator or heating vent. Be careful to not block its air vents, particularly when doing something demanding.

I hope this helps in fixing the heating issue.
