This is my solution to the CM3 heat problem... Its a few layers of copper sheet cut with heatsink compound between each layer and then araldite applied around the outside (not between the layers!). Finally some heatsink compound on the 2837 chip on the CM3 and you've got an awesome heatsink...

Gordon,
Have you glued it onto the Slice case, presumably to stop it moving about?
Thanks
