A Closer Look

With a height of 159.5 mm, the Thermalright HR-01 is the tallest heatsink in this round-up. However, it is also the narrowest heatsink as well.

From these pictures of the HR-01 at different angles, you can see that it has a symmetrical design. Although there appears to be eight heatpipes, there are actually only four of them.

Each heatpipe is U in shape, with the middle soldered to the heatsink base. One branch of the heatpipe will go through the outer end of the fins, while the other branch will go through the inner part of the fins.

The LGA775 mounting clip (the four plastic clips) were attached to the heatsink right from the start. That saves you some time installing them yourself.
