This is not exactly how your video card will look like - but it shows the fan about half way thru:
I did not listen to the audio - so I don't know what the guy said...
...hence no endorsement of the info presented.
I'm also not suggesting that you replace a fan as shown,..
...it is just the first video that I found for you.
Do not use a regular vacuum cleaner to clean dirt/dust from a computer. Compressed air was mentioned or take it to a professional.
