Following along with our look at some new 1U
coolers, Frostytech will be testing out the CoolJag 2QC/180 1U socket
478 skived copper heatsink in this review. The 2QC/180
is actively cooled with a 15mm-thin squirrel cage fan that intakes air
through the body of the heatsink, before exhausting it out through another set
of copper fins.
entire heatsink measures no more than 27mm in thick, and attaches to socket 478
Pentium 4 motherboards with the aid of metal back plate and set
of spring tensioned screws. The stock m478 heatsink retention
mechanism will need to be removed before the Cooljag 2QC/180 can
be installed, making installation a little time consuming. The CoolJag
2QC/180 is available through SelectCool, a division of heatsink
manufacturer of Dynatron.
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 in most cases 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
from case fans however.
Everything that you need to
install this heatsink onto the motherboard is included along with the heatsink. The
spring tensioned screws helps to prevent the heatsink from sitting askew on the core of
the processor, rather than with evenly distributed force.
The metal tubes slide inside the
springs to prevent problems from over tightening the screws, and potentially bending the PCB to a point that
