Whenever I start my computer, I am prompted to hit enter to activate the fans. Is there some way I can verify fans working properly.
I think you are better asking on a technical help forum. I suggest Bleeping Computer there is a wealth of knowledge amongst the member there:

When asking there include the make and model of your computer, and say what Operating System you are using.
They might also ask for a Speccy report so that they can see which motherboard etc. you have, which can be relevant for diagnosing things like cooling fans.
