EVGA ACX 3.0 Cooler
Now let’s talk about how EVGA keeps their GTX 1080 FTW cool with ACX3.0 cooling. This technology uses two dual ball bearing fans for over 400% longer life compared to sleeve bearing fans used by almost every other card.
Not only do the ACX 3.0 fans last longer but they also have a 4x lower power consumption than leading competitors. And lower power consumption equals more power to the GPU for overclocking.
One of the most noteworthy features of the GTX 1080 ACX 3.0 cooling system is, of course, the RGB LED. While having absolutely nothing to do with performance, it definitely adds more eye candy to your already decked out computer case. And with EVGA PrecisionXOC you can customize that eye candy whichever way you like.
The award winning EVGA ACX is honestly the best cooling system I’ve seen on a GPU so far. Not including water cooled systems of course, like the EVGA hybrid and EVGA HYDRO COPPER. But for a standard fan cooling system the EVGA ACX is definitely one of my favorites.
EVGA has even optimized the way their fans curve with swept fan blades allowing for 0 dB operation, and minimal power usage. And let me tell you, this card does not make a sound.
EVGA’s innovative design has also implemented more advanced heatsinks. By using straight pipe heatsinks instead of bent pipe EVGA has reduced heat by 10%.
Another innovative design implemented by EVGA is the memory/MOSFET cooling plate, that sits right on top of the GDDR5X memory modules. Bottom line, the GTX 1080 from EVGA stays cool and whisper quiet, with extremely low power consumption, and advanced ACX3.0 cooling technology.
EVGA has once again pushed the boundaries of innovation and their dedication to performance is undeniable with the ACX 3.0 cooling system. Utilizing optimized swept fan blades, double ball bearings and an extremely low powered motor to delivering more air flow with less power. Which also unlocks additional power for the GPU.
That is the ACX 3.0 Cooling, in a nutshell. Now let’s go over how our EVGA Geforce GTX 1080 FTW GAMING ACX 3.0 is powered with EVGA’s 10+2 phase power design.
EVGA 10 Phase power design Geforce GTX 1080 FTW GAMING ACX 3.0
As you can see in the picture above EVGA has designed this card with a 10+2 power design. Surrounded by the memory/MOSFET cooling plate for more efficient heat dissipation.
So first off, Your power supply unit “PSU” converts 120VAC from your power outlet to 12VDC so your computer components can use it. Once converted the PSU distributes the 12VDC power as needed to each individual component.
Second, the GPU power phases are pretty much just multiple DC-DC buck converters. The purpose of the buck converters is to reduce the 12VDC down to whatever the GPU die requires. which is around 1v. And for such small voltages, the die “gp104” requires massive currents.
So the more power phases implemented the more the converters can handle the increased current requirements as seen with intense overclocking and also help spread the increased heat evenly avoiding thermal hotspots.
Although not the most important feature in making this a real EVGA FTW model, it is definitely something to consider when looking at overclocking capabilities. It is also important to note that power phases and heat dissipation work together hand and hand when overclocking.
Since more power equals more heat even the 14+3 power design “as seen on the EVGA GTX 1080 Classified” is nothing without proper heat dissipation and cooling. When your GPU is overheating you cannot supply more power to it.
Moving forward, it’s time for the final page. Wich will be concluding my review on the EVGA GTX 1080 FTW GAMING ACX 3.0. Keep reading to see my final thoughts on the matter.
