EVGA GTX 1080 Ti FTW3 Tear-Down
The rest of today’s discussion will stick with the non-power componentry and cooler configuration.
EVGA’s running six cables along the PCB: One on the backside (RGB LED nameplate), three fan headers on the frontside (all along the bottom), a power cable on the right side, and an LED synch cable at the top. The top cable synchronizes the LEDs from the MCU and the backplate, if desired.
Each of the three fans is individually controlled by MCUs on the board, slaving to sensors that we’ve defined heavily in previous ICX content (initial deep dive, follow-up SC2 review).
The FTW3 heatsink sticks with overbuilding by design: Protruding cylindrical fins extend from the baseplate covering the middle VRAM modules and capacitor banks, further covered by a two-part finstack bridged by five heatpipes. A few different types of fins are used for the heatsink, too. L-shaped fins sit over the excessive VRM thermal pads to improve surface area contact to the thermal interface while still permitting airflow, better than straight fins for contact area. Straight fins are still used in regions that hover over the baseplate without contact, and squared fins sit in areas of the board that don’t need the extra airflow.
It also helps that the PCB is oversized, allowing for wider fans at lower RPMs (and without expanding width of the card).
We’ve got several interesting tests we’re running on this card, so be sure to closely follow the site & channel while we crank through those.
