MacAir 11'' A1465 - Overheating

Hello guys,

I own a Macbook Air A1465 from about 6 years. I am currently facing overheating issues with my mac. One of the Cpu core fans especially the one on left of keyboard is making whizzing sound and keyboard is getting heated too. I tried Fan Control Softwares but to no avail.

I tried giving Mac to Apple Service centre but they said they wont take up any obsolete product for servicing. I am trying third-party service centres. They have asked me that they are trying lookup for the Macbook Air A1465 exhaust fan component, ma de by Vendor "Concorde". Can you please assist me where can I get it or how I can fix this overheating issue?? Thanks.
