Weird rattling noise from one of my fans

[probablydumb]

So as the title suggests one day i woke my pc up from sleep mode and one of the fans started making a rattling noise. It was the middle fan from the 3 ones in the front and when i checked to see where the sound was coming from it was coming from i saw the middle fan kinda spinning slower than the other ones but it was still spinning at high speeds.I closed my pc opened it back up and the rattling was gone.So i called it a random event and continued on. Same day (today) I opened my pc up and nothing the first 10 seconds but then the middle fan started to act up again, hearing the same noise.I put my pc to sleep mode and opened it back up then boom.Nothing the rattling was gone again.Is this like a random thing that sometimes happens or is there a cable in the way of the fan or something getting stuck in it? Maybe dust or anything else? The fans are not even old only about 2 weeks.What do you guys think i should do?

Check to make sure nothing is in the way of the fan

 

also make sure that the fan is not faulty

 

if you can disassemble your fan, check if there is something in the rotor

 

when all else fails, Amazon has 2 day price shipping

Take a flashlight, turn off the pc, and closely examine the fan. Check inside, outside, sides. Every angle you can. See if you can see something that is not supposed to be there
