FYI: Cooling your tank - Aqua Medic 'Arctic Breeze' fans

Hi all,
This isn't a review persay, but given there is a lot of talk/questions about cooling the aquarium, and we generally always end up recommending fans (evaporative cooling), I figured I'd let everyone know what I've found :;hf

Aqua Medic have sets of aquarium fans that clip on to the glass (from what I can tell), and whilst probably more so designed for the SW setup, I reckon they'd work on FW too.

The claim to be able to reduce temp's by 4C.

More info:  

I haven't actually purchased these, and can't find pricing on them in Aus, but I reckon they'd be a lot cheaper than a chiller unit.
