Hi Ankith

Welcome to the community

I would recommend you to turn off the system and unplug AC adaptor remove the battery as well and use compressed air to blow the dust out of the vents.

Please check the vents on the computer to see if they are covered with dust and not allowing heat and air to pass through. See the example below:

For more information type this article no. ( 279891 ) on support.dell.com 

please let me know for further help
