Loud fan noise on 27" LED Cinema Display

[xyro]

Hi,

I've bought a refurbished late 2011 MBP (with TB) and am using it with my 27" LED Cinema Display. Unfortunately, it seems this combination is making the fans inside the cinema display spin up quite a bit, with a continuous low hum.

Previously, I was using a late 2008 MBP with the cinema display and it was working fine until the cinema display fans started making some noise after about a year of use (alas, I did not get Apple Care ...). This noise was predictable though: the higher the brightness settings, the higher the fan speed, the more noise.

With the 2011 MBP, it seems the fans are spinning in a lot more on-demand fashion: if i switch from my browser to Mail, and start scrolling through my emails, the fans become audibly more agitated. There is no difference is perceived brightness. Same thing happens if I start up an application and a new window pops up.

EDIT: I just tested the screen with the old macbook pro ... same issue so it seems to be entirely a faulty fan in the screen, and not because of using the new macbook pro.

This is strange, and a little bit disappointing. So I am wondering

1) Does anyone have similar issues with their display fans?
1) How would I go about opening up the display and fixing it?

Thanks!

If you have a problem with it why not go to your local Apple store?
