At home in the air and underwater: Asus GTX 1080 Ti ROG Poseidon Platinum in test

All of this sounds simple at first, even in practice. Instead of a water block, simply place a flat heatpipe on a large heat sink and optionally let water pass through to absorb the waste heat and transfer it. 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.

Cooling system and backplate

The special feature is the use of a hybrid system that can be operated both in a water cooling system and only alone with air cooling. The advantage is that the buyer does not lose any warranty claims due to a cooler change if he wants to upgrade to water cooling later (perhaps).

Cooling system at a glance
Type of cooler: Hybrid cooler for optional air or water cooling
Heatsink: Copper Heatsink with mounting frame
Water cooling by lying, U-shaped pipe for water flow
No micro-channels or other contact cooling
Cooling fins: Aluminum, horizontal alignment
very close
low depth
Heatpipes 2x 8mm, flat and nickel-plated
VRM cooling: integrated in the Heatsink
only MOSFETs are cooled
RAM cooling via mounting frame on the heatsink
Fan: 2x 10 cm fan modules (gross)
9.6 cm rotor diameter
13 rotor blades, optimized for static pressure
semi-passive lyrised
Backplate Aluminum, blackened
internally foiled
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 heat sink relies on a copper heat sink, which can also be used as a cooling block for water cooling by means of a flooded heat exchange pipe. The standard thread connections can be used on the front and rear. However, it must be expected that the very narrow tube greatly reduces water flow, depending on the cooling concept.

Similar to a vapor chamber, the heatsink is large-scale and is additionally thermally connected to the rest of the slat cooler via two additional heatpipes.

The internal radii of the heatpipes are very tight and not optimally worked in terms of quality. In addition, such trivially flattened designs are very quickly prone to performance degradation in the flow inside.

Fan curves and noise emission ("volume")

The fan curves indicate a conservative and volume-optimized control.
