Whirring sound from right fan (rMBP)

[Rumourhasit]

I have a 15in early-2013 rMBP and just recently started hearing subtle whirring sound from the right side of the computer. Has anyone else experienced this?? Any solutions? I might have to replace the fan, god knows how much it'll cost

If you're handy with a screwdriver, you could do it yourself.

Check out iFixit.

I've had both fans replaced under Apple Care. I don't think I still have the paperwork, but 90 bucks a fan comes to mind.

Open up the Mac and check for dust. If any, blow it out with a can of compressed air. If it looks good, fan bearing might be going out.
