Closer Look:

We have looked at the case and pump for our project and now have reached the next item in the cooling loop, the radiator. This is the device that actually transfers the heat generated by the cpu, graphics card and pump from the liquid medium to the surrounding atmosphere. This is accomplished the same way as on a motor vehicle. With the motor vehicle the heat is generated by the combustion cycle instead of a piece of silicon. The heat is transfered to the liquid coolant (antifreeze), and that is continuously recirculated through the motor by a water pump. The radiator has a fan pulling air through it, exhausting the heat to the atmosphere and lowering the temperature of the coolant. In all, its a pretty efficient process that is the same across both platforms.


The box the radiator came in is a simple cardboard box labeled on the end to identify the product.



Opening the box we can see that the radiator is nestled inside with a blocked-off section containing the fittings and mounting screws.



The fittings we have chosen for the kit are 1/2" and are included along with the mounting screws for the fans and case mounting. The fittings come with an o-ring seal, but no additional means of sealing. I used teflon tape as an additional means of sealing the fitting to prevent any leaks.



The fittings screw into the face of the end of the radiator. Screw the fittings in until the o-ring touches the base and tighten down until the o-ring starts to bulge.


Closer Look:

The fans that we have chosen are made by Papst and are 120mm x 32mm and push 55.9 CFM. Two will be mounted to the radiator to provide the airflow to effect the heat transfer from the cooling fluid to the atmosphere.






The fans mount onto the radiator with a series of short stainless steel screws. The length is critical to keep from hitting the cooling tubes on the radiator. The fans sit two wide and cover the surface of the radiator.



The tubing that that we have chosen to use is manufactured by Tygon and was chosen for its elasticity and ability to bend without kinking. The dimensions of the tubing are 1/2' inside diameter and 3/4" outside diameter.



The clamps and fittings that come with the kit we have chosen are the basics to get the job done without a lot of flash. Included in this kit are the clamps, T-fitting, line plug and some Ceramique thermal paste.



The clamps are plastic and push together to lock. The clamp encircles the tubing to provide a leak proof seal.



One handy tool that was included in the kit was a 60cc syringe for filling the system.
