A1 is testing an Evercool fan and sink for A64. If you can pick out the right colors in the graph you can see it is an OK, but not outstanding performer.

copper heatsink compared to the EverCool Magic Cooler we reviewed earlier
which is Aluminium with a Copper insert. It must be remember that both these
EverCool heatsinks are much smaller and lighter than the other heatsinks
shown here.
