On the ASUS Trinity, the cooling task is handled by the Thermaltake Bigwater 760 is.

The Bigwater unit mounts into two 5.25-inch bays in your casing, and since the air from the Bigwater is downward flowing, it is recommended that you leave some space below to prevent building up of heat in the bay area, and also heating up your optical drives unnecessarily.

The 120mm fan on the Bigwater is of variable speed nature. It can be adjusted between 1800rpm to 2400rpm.

The ASUS Trinity is cooled by the equally-impressive Thermaltake Bigwater 760 is mini watercooling unit.

 

Flipping the Bigwater unit over, reveals a jet black painted single 120mm radiator.  The radiator sports Dimple Tube Technology with louvered fins to increase surface area for better cooling. Thermaltake calls it a 'motorsports radiator'. Dimple Tube Technology is essentially an advanced design that utlises dimpled tubes to create a swirl of the coolant within the radiator itself.

 


A single 120mm radiator here, but it is more than sufficient to cool the ASUS Trinity that's running on Radeon 3850 cores.

 

 The waterblock is connected to a single pair of 3/8-inch tubings.

 


A simple flow design; one tube pipes the cold water in while the other carries the heated water out to the radiator.

 

Taking a look behind the ASUS Trinity card itself reveals a set of heatpipes soldered on to a rectangular waterblock. Heat travels via the heatpipes from each of the cores to this waterblock, which is cooled by the Bigwater. This brilliant design elimates the need of running tubings from the middle of the card, or even from each of the cores.

 


 Heat is removed from the Radeon 3850 cores via heatpipes to a central waterblock.

 

Peeking at the rear of the Thermaltake Bigwater 760 is unit reveals a P500 pump and and a small coolant reservoir. There should not be any issues with cooling this card since the pump has a flow rate of 500L/hr. The refillable reservoir has a capacity of 350cc.

The coolant tank is translucent and has level markings, while a small pump hidden at the back keeps the coolant going.
