weird ticking while playing battlefront (2015)

[ORKblaze]

i bought battlefront for my pc recently and i noticed a weird ticking coming out of my PC. when i closed the game it continued for like 30 seconds and then and it was gone.at firest i thought something is wrong with one of the components but the fact that it has stopped when i closed battlefront makes this impossible. please help.
thank you.

It could be a hard drive, or it could be a fan that is slowing down once you remove the gaming load (and heat).

While it is happening, you need to isolate the specific part that is making the noise.
