Every CPU cooler I have received from Thermalright comes in a pretty nondescript plain brown cardboard box with just enough information to allow you to know you have the right box in your hands by seeing the Thermalright name and logo printed on the top of them.
On the right side of the box you see the Silver Arrow SB-E name and logo on the side, but with this version there is also the large X logo with the word Extreme pasted across it.
The left side is the only other part of the box with information on it. What is shown here is an inverse of the opposite side, if you are buying with a phone in hand; at least you have the web address so that you can look up the specs on this cooler.
Just taking a step back to show that Thermalright isn't about wasting money on the packaging, and that I wasn't skipping anything; the front, back, and bottom of this packaging is completely blank.
When you lift the front panel out and lift it and the top panel out of the way, you are greeted with the paperwork, a sticker, and a look at some foam and plastic.
Each of the 140mm fans are placed on either side of the cooler with the hardware box stuffed between the towers. There is a plastic liner over the body of the cooler, but to keep the components safe, Thermalright uses high density foam to isolate these and deliver a product that arrived in great shape.
