Asus ROG Strix GeForce GTX 1080 Ti OC in review

Asus uses the same board as the ROG Poseidon Platinum hybrid card, but with slight modifications to capacitor assembly. Otherwise, the Strix cooler of course has much more space, which can only be advantageous. The Kart... Asus uses its own design for this board. The two 8-pin sockets for the external power supply are followed by two coils in the input area for smoothing the tips. Asus relies on a design of 5+2 phases, with the 5 phases for the GPU being designed.

Cooling system and backplate

The special feature is the use of a "sandwich" system, which uses a kind of cooling and stabilization frame between the top of the board and the actual heat sink. Unfortunately, Asus dispenses with an integrated VRM heat sink in the cooler and the direct cooling of the memory modules.

Cooling system at a glance
Type of cooler:	Air
Heatsink:	Nickel-plated Heatsink, GPU-Only
Cooling fins:	Aluminum, horizontal alignment related
Heatpipes	6x 6 mm, nickel-plated
VRM cooling:	only via cooling frame only MOSFETs are cooled
RAM cooling	via mounting frame and indirectly via the heatsink
Fan:	3x 9 cm fan modules (gross) 8.6 cm rotor diameter 11 rotor blades semi-passive lyrised
Backplate	Aluminum, blackened no cooling function with backlit logo

The backplate is purely for optical enhancement and bears the ROG logo. It does not pay any amount for cooling.

The previously mentioned cooling and assembly frame absorbs the waste heat from the memory modules and also releases it to the GPU heat sink via a further layer of thermal conduction pad. The voltage converters are also cooled by this frame, which still looks for contact to the cooling fins above this area by means of a thick thermal guide pad. Since these have not been angled by 90° in this area, it is reasonable to assume that this solution was only subsequently introduced. In order to stabilize this contact a little better, the cooler is still lying on a thick adhesive pad.

The heat sink is nickel-plated and very smooth. Asus relies on a total of six fast, nickel-plated heatpipes made of composite material, the radii of which are relatively large at the necessary bends. This, like the slightly smaller diameter, ensures better performance.

Fan curves and noise emission ("volume")

The fan curves indicate a rather conservative and volume-optimized control. The hysteresis is a bit hilarious, but the number of starting pulses is just fine, but without being particularly disturbing.

The whole thing does not look much different in the stress test, although due to the slightly lower power consumption the speeds are also slightly lower.

Measurements for fans and noise emission
Fan speeds Open Benchtable Maximum	1715 rpm
Fan speeds Open Benchtable Average	1702 rpm
Fan Speeds Closed Case Maximum	1884 rpm
Fan Speeds Closed Case Average	1874 rpm
Noise emission (air) Maximum	39.0 dB(A)

Sound characteristic / Hearing impression	hardly lower frequency bearing noises clearly audible engine noise< 1 Hz Oscillations due to slightly different fan speeds hardly spool-feathers audible air/demolition noises
