I've set a few of these up in offices now for clients, and noticed that from time to time they click, almost as if they are being switched off and on again.

It's not really bothered me until I've set one up at home, and it's located behind my TV in the living room. When I'm sitting here I can hear it do it every few minutes. It's a bit irritating, especially when I've invested huge amounts of money in making my home cinema PC silent!

What is it and is there any way of switching it off?

Cheers

Try a search first.
