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
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.
that a 1U of space in a 19" rack equates to a server 1.75" thick, there is
typically no more than about 30mm of vertical space for the entire processor
cooling solution; heatsink and fan. Most commercial servers will tend to use
fully passive heatsinks, and engage airflow with the use of an array of 40mm fans.
For smaller servers, handling Firewall or VPN requirements, less noise
intensive cooling solutions are used for what is typically a standard desktop mainboard
inside a small 1U server chassis. For these applications, this copper skived
heatsink and squirrel cage fan design makes sense. For production critical
servers, it is always best to go with passive heatsinks, and forced air cooling
from case fans however.
Everything that you need to
install this heatsink onto the motherboard PCB is already in place and ready
to go. The screws are spring tensioned to evenly distribute the force and prevent the heatsink from
sitting askew on the core of the processor.
The metal fan shroud helps to duct the intake air through the series
of copper skived fins, before it is sucked into the fan and exhausted
