Thermalright XP-90C Heatsink (All Copper)

Examining the XP-90C:

The XP-90C comes in the same style box as the XP-90, inside everything is neatly packaged to prevent damage during shipping. There are a lot of accessories included with the heatsink, a manual, sticker, thermal compound, screws, two sets of fan clips (80mm & 92mm), and two sets of retention brackets. An all-metal S478 retention bracket is new to the bundle, as it was not included with the original XP-90. I guess the additional weight of the all copper design was putting too much stress on some of the cheaper S478 brackets included with motherboards. For S775 users, a special bracket can be purchased separately.

When you pull the XP-90C out from the box, the first thing likely to be noticed is the weight. But the second thing to be noticed is how big and shiny the heatsink is. Design-wise it is a duplicate of the XP-90, just made entirely of copper.

With a 92mm Tornado fan mounted on top of the heatsink, the whole thing almost looks like a work of art. I included a side-by-side picture of the XP-90 & XP-90C, same but different.
