Elite Bastards posted a review on the SilverStone NT04 CPU Cooler

Here, we get a nice view of the shiny, gold coloured 80mm fan that cools the NT04's heatsink. This sits just above the heatsink itself, leaving more of a gap than the PIAB cooler does. The bottom of the cooler, as I said above, is fairly smooth, but not perfect... a few imperfections, but nothing a little work couldn't fix. The cooler also comes with TIM (Thermal Interface Material) already applied to the heatsink, like the PIAB cooler.
