Given the thermal performance of the EU01 as a 1U heatsink things are good. As a desktop heatsink it doesn't quite have the thermal capacity in light of the vast number of competing heatsinks however. As a SFF PC, or 1U heatsink the EU01 is good for say, the AthlonXP 2100+ range.

The manufacturing quality of this heatsink is not a very good example of what Eumax want to show to the world. Having arrived with one copper fin falling out, and with a base that looked as though someone had taken a nail to the surface, there isn't much here to illustrate any level of significant quality control on the part of Eumax.

Had this heatsink been installed in a system, a potentially disastrous situation could have occurred. Just imagine tilting the computer onto its side to install the heatsink, then closing up the side cover and standing the system back up only to have one thin piece of highly conductive copper come loose and land on the back side of a brand new videocard.... Even the slim chance of an electrical short is just too much to gamble with despite the relative thermal capability for a hight-limited heatsink such as the Eumax EU01.

Therefore, because manufacturing process used to assemble this heatsink not sufficiently refined I recommend avoiding the Eumax EU01 entirely. What could have been a pretty decent cooler for small form factor system, or other height-limited enclosure, just contains too much potential for system damage. Bottom line, the Eumax EU01 fails because of poor Quality Control.
