Cooljag 2QC/180 1U Socket 478 Heatsink Review
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.
The 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.
Given 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 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 causes damage.
