Sapphire’s Radeon R9 Fury Tri-X makes use of a custom heat sink design featuring seven copper pipes of varying thickness and two separate sections of fins to dissipate thermal energy generated by the GPU and HBM. The central pipe is a gargantuan 10mm thick; two 8mm pipes flank it on each side, and these all span from the main section of fins over the GPU to a separate group of rear fins. The remaining two pipes are 6mm thick, each making a single loop back through the fins over the GPU contact block.
The card's PCB is quite short at only 12cm. However, the heat sink and shroud extend well beyond the back of the board. In fact, they nearly double its length, taking it to 23.5cm. The rear section of the cooler is wide open, with only a die-cast exoskeleton holding it in place. This facilitates significant airflow through the heat sink fins.
Sapphire said it was targeting a load temperature of less than 75 degrees C and modest acoustics as it designed the Tri-X cooler. The company uses three dual ball-bearing fans managed by advanced profiles, which ramp up the fans slowly in order to maintain silence when possible. Under normal load, the fans should spin at 40% or less, though they can be manually adjusted if more cooling capacity is desired.
Not only is the R9 Fury Tri-X quite long, but it is also very thick. The card measures 5cm from the shroud to the screws sticking out of its back plate. Clearance may be an issue for some motherboards. It came close to not fitting in our reference board's first PCIe slot. If the back plate was 1mm thicker, it would not have worked.
Despite the card being technically capable of running four-way CrossFire, the heat sink blocks a neighboring PCIe slot. So, short of using riser cables, you’re limited to double-spaced setups unless you opt to replace the sink with a water block, which Sapphire actually cautions against.
According to Sapphire, the heat sink's design is rather intricate and it was adamant that we couldn't remove it during our review. Apparently, because the HBM modules sit higher than the GPU, it's very difficult to replace the cooler correctly, which can result in poor cooling performance and possibly damage the GPU.
Along the top of the card, you’ll find two eight-pin power connectors. A row of eight LED lights are positioned next to those auxiliary inputs, and they illuminate sequentially to indicate higher load.
Sapphire also includes a BIOS toggle switch that switches between two slightly different profiles. One is tailored to a 75 degree C load temperature target and keeps power going to the GPU limited to 300W. The second option allows for an 80 degree threshold and a 350W power limit.
AMD’s Fury X was designed without a DVI port, and the Fury follows its lead. The I/O plate has three DisplayPort 1.2 connectors and one HDMI 1.4 interface. Up to four displays can be driven natively, but six are supported through MST hubs.
DVI is still supported through a DisplayPort-to-DVI adapter, which Sapphire graciously includes in its retail package. The company also adds an HDMI cable.
