This is the third in a series of similarly designed 1U full copper heatsinks from a company called CoolJag that FrostyTech has had the opportunity to test. Called the JACE2DC/180, this particularly heatsink shares most of its similarities with the CoolJag 2QC/180 1U cooler, save for a slightly different skived fin structure. The Cooljag 2QC/180 has an extra set of tall copper fins on either side of the squirrel cage fan, whereas the JACE2DC/180 we are testing here, maintains the same 7mm tall fins from end-to-end.

All of the 1U heatsinks from this series from Cooljag, employ active cooling from a 15mm thick Everflow squirrel cage fan set to intake cool air through the copper fins. The entire heatsink measures no more than 28mm in thick, and attaches to socket 478 Pentium 4 motherboards with the aid of metal back plate, and pre-installed spring tensioned screws. The stock m478 heatsink retention mechanism will need to be removed before the Cooljag JACE2DC/180 1U heastink can be installed. This may make installation a little complicated, depending on how tight things are in the 1U chassis. The CoolJag JACE2DC/180 is available through SelectCool.
