Thunderbolt monitor makes faint ticking noise

It's only a month old. At first thought it was my Apple wireless keyboard, but figured out it's the TB monitor.

It's a faint ticking/clicking sound every 30 or so seconds upon waking up from sleep or start-up. After 10-20 minutes it finally goes away (or I just don't notice it). But if I put the monitor to sleep then wake it up, it starts all over again. Tried installing the firmware update (version 1.1) posted by Apple on Dec 12, 2011 but when launching the installer, I got a message saying I didn't need it.


Any suggestions please? It's connected to an equally new 15" MacBook Pro on 10.7.2.
