Packaging and Overview
Asus ROG STRIX GeForce GTX 1080 Ti comes in identical Asus ROG box as the GTX 1080 with card picture on top and features overview at the back.
The first and most noticeable change from the previous STRIX GTX 1080 is the new reworked Strix DirectCU III cooler is bigger and thicker. We will cover the cooler later and see what kind of improvement it offers. On the front, the card features a triple “Wing-Blade” fans with integrated RGB Aura lighting. The ASUS ROG STRIX GeForce GTX 1080 Ti is 11.7 inches in length and 2.5 slots thick.
In the back, ASUS didn’t make any changes to the back plate design from the previous cards, with a big ROG eye which is RGB illuminated.
Dual 8-pin power connector powers the card. On the left corner, we can see two SLI connector.
In the rear side of the card, we find two 4-pin PWM fan connector for case fans, which will control by the card to give maximum air flow over the card. ASUS also added an RGB header which allows you connect your case RGB strip with the card and control by the AURA software.
As you can see the card is taller than the reference design. The display output includes one DVI, two HDMI, and two DisplayPort.
I am little disappointed to see warranty void sticker on one of the screws, as ASUS in the past allows their enthusiast card owner the freedom to change the thermal paste or clean their cards. That’s said, let’s open it and take a close look at PCB.
Now let’s take a look at the new cooler, if you read my ROG STRIX GTX 1080 review you know that, the cooler did not perform very well with the card running at 78° C and there for not boost as much as other GTX 1080s I tested. Now ASUS has addressed this issue with a bigger cooler. As you can see the new cooler has a thickness of 2.5 slots and have more fins to dissipate more heat. You can see the size difference between two cards.
The cooler is attached to the backplate with six screws, to remove the cooler completely you need to disconnect two power connectors, one for the fans and one for LEDs.
The DirectCU III has 6 heat pipes (compare to 5 heat pipes on Strix GTX 1080 cooler) with two aluminum fins stake. But the heat pipes didn’t directly touch the GPU core, there a base plate which makes contact now for maximum heat dissipations.
The new design also features a bigger metal heatsink that covers the MOSFETs and the memory chips. This metal plate also acts as a support and help to reduce GPU sag.
As you can see ASUS uses a complete custom PCB design with their high-quality Super Alloy Power II components, with 10+2 phase VRM design to offer maximum power for any overclocking situation. ASUS also claims their Super Alloy Power II will provide thermal levels that are approximately 50% cooler than previous designs.
We also can see the ASUS using Micron GDDR5X memory and it covered by the metal plate for added cooling.
