Everything is packed neatly inside and well protected by foam.
The instruction sheet is laid out very nicely, complete with diagrams and easy to read quality print. The last product I reviewed from Thermalright came with an instruction sheet that looked like a bad photocopy, so it is good to see they have corrected this.
Besides the instructions and the heatsink itself, we also get fan clips, anti-vibration strips, thermal paste, a new socket mounting frame and a Thermalright sticker.
Unfortunately they haven't changed the sticker design, it's still kind of blah.
As mentioned previously, the cooling fins are not directly soldered to the base like most heatsinks, but instead rely on the heatpipes to convey the heat away from the base.
Since the fins do not extend down to the base, the top portion of the SI-120 is supported only by the heatpipes and these 2 hangers.
As on the XP-120, the SI-120 utilizes a total of 5 heatpipes between the fins and base. The majority of Thermalright's smaller heatsinks use only 4.
