I've been trying to find some of the Zalman coolers for sale in the UK, but I can only find coolers for modern graphics cards, none of the old small-form coolers.

This morning I've found the Vantec Iceberq4 Pro. Cheap, too.

It looks like it will do the job - has anyone else used one of these on their cards? My fan has a nice crunchy rattle to it, so I'm keeping an eye on the temperature sensor!
