Buzzing noise from a fan when starting up, worry?

[Hoppled]

After dusting my pc due to high temps, I noticed a loud buzzing noise that happens every time I start up the PC, then it completely goes away.

The dusting greatly reduced my temperatures while gaming. (GPU went from peaking 76 C to peaking at 56 C)

Except, now, I get this buzzing noise at start up. What I worry is something might be damaged. I remember I didn't have an air can so I vacummed inside, specifically the dusty fan of my GPU- I remember I put the nozzle into the fan for a bit and it made a noise like the fan was hitting it (obviously the PC was disconnected). I double checked for damage and it seemed fine, the fan rotated nicely still.

The computer works fine, temperatures are lower now, except this buzzing noise at startup. Should I worry? I will turn it on with the case open next time to see the exact culprit for the noise.

Ok where is the noise from? Speaker on Motherboard, a Fan, what???
Find out what makes the noise and address it; a fan? Replace it.

Im gonna find out where its coming from but, why replace if it's only when it boots up?

Never use a vacuum inside a PC; vacuums themselves just generate static.

And when you clean a Desktop/Laptop; whatever the method; don't let large amounts of air pressure to turn the fans. That's an easy way to break them. Firstly you can break fan blades that way. Second the bearings inside. They were designed with a certain max RPM in mind; if you are forcing a fan beyond that, you are basically killing the bearing inside.

Use compressed air and a brush; it's much safer.

Well I checked the fans after they spun fin. So then it must be the bearings making the noise? Because like I said, the computer is completely silent after it starts up, like nothings wrong.

Also, if the fan noise is coming from the gpu (remember the only issue I'm facing is a buzzing noise ONLY when it starts up) then how would I replace the gpu fan? Don't tell me I gotta spend 200 dollars now to fix this ♥♥♥♥♥♥♥ buzzing noise

GPU Fan failures are covered by warranty from the GPU manufacture.
But yea it is probably just one of your fans somewhere in the system; once up to speed it goes away.

So will my computer be fine since its silent most of the time anyway?

The buzzing noise has seemed to stop completely when I start up now. Odd.

Could be vibration or bad bearings.

Another annoying buzzing sound is coil whine.

well it's completely fine now so I'll wait and see. I never ended up looking in the case so possibly could of been a wire, considering it stopped all of a sudden.
