THE HR-22

We did say that the HR-22 is massive right? Well with 159mm in height, 150mm in length, 120mm in width and a weight of 1120g it surely is.

The body of the HR-22 features a grand total of 35 aluminum fins each 0.5mm thick.

Aside the large hole at the top which is used to secure the cooler with the mainboard the other holes are in place to enhance airflow.

To better understand how these holes improve airflow you will need to take a look from either side (these holes basically keep the air trapped between the fins). From the side you can also see that thanks to the design of the heatsink it will not interfere with memory modules and mainboard components.

This is perhaps the only time that we've seen eight 6mm all-copper nickel plated heatpipes passing through the base of a CPU Cooler and through all of its fins.

As expected from Thermalright the copper base features a nice mirror like finish.

Although the HR-22 has the 120mm version of the airflow tunnel bundled with it (you connect the back of the cooler to your rear exhaust case fan) Thermalright also send us the 140mm version which we ended up using (although i don't think both are sold together).
