The ASUS GTX 670 DirectCU II is 23.2 cm long measured from the rear panel to the far edge of the circuit board and the cooler adds an additional 3.5 cm to its length. The heatpipes also hang over the edge of the PCB, increasing its effective width by 2.0 cm. The heatsink accounts for 500 grams of the card's 710 gram total weight.

The heatpipes protruding out the side are noticeably thick, making the heatsink seem quite formidable. The fans aren't particularly large for a dual fan GPU cooler, though, equivalent in diameter to a standard 80 mm case fan and very thin in profile.

The card has a standard set of video outputs: DisplayPort, HDMI, DVI-I and DVI-D.

The trace side of the PCB is covered with a thick metal backplate secured at multiple mounts. Ventilation holes have been punched out over much of the surface.

The backplate extends over the edge of the PCB forming a grill. The card's two 6-pin PCI-E power connectors are positioned on the side so they don't add any length to the card. However one of the heatpipes nearby makes it difficult to get a grip on the release underneath the plugs.

The heatsink is secured only by four spring-loaded screws on the back. It has three 8 mm thick direct-touch heatpipes made of copper which intersect aluminum fins at three different spots. The fins are approximately 0.42 mm thick and spaced a tight 1.35 mm apart.

The PCB layout is remarkably tidy with nothing notable interfering with the area around the GPU core. There is no additional cooling aside from the backplate and a small black heatsink near the rear of the card, presumably for the voltage regulation circuitry.
