EVGA GeForce GTX 1080 Ti Black Edition

The EVGA GeForce GTX 1080 Ti Black Edition is a graphics card built for high-resolution gaming and VR workloads. It uses the NVIDIA Pascal architecture with 3584 CUDA cores and an 11GB GDDR5X frame buffer. Core and boost clocks run at 1480 MHz and 1582 MHz respectively. The card communicates over a PCI Express 3.0 interface.

iCX Cooler and Precision XOC software

The iCX cooler uses redesigned L-shaped contact fins and a vented heatsink with pin fins to increase surface area and optimise airflow. EVGA Precision XOC is included for monitoring and overclocking control. These features work together to manage thermals during sustained load.

PCI Express 3.0 and display outputs

The card connects via PCI Express 3.0 and provides 1 x HDMI 2.0b, 3 x DisplayPort 1.4 and 1 x Dual-Link DVI. It supports up to four simultaneous monitors at a maximum resolution of 7680 x 4320. Bandwidth and feature support are defined by the 3.0 standard and the output specifications.

Questions about this item

Will the iCX cooler on this GTX 1080 Ti need thermal paste replacement or fan maintenance later?

The iCX cooler uses L-shaped contact fins and a vented heatsink design for heat dissipation. Standard GPU cooler maintenance applies: dust the fans periodically and replace thermal paste if temperatures rise after several years.

What hits its limit first during long gaming sessions — the 352-bit memory bus or the 11 GB GDDR5X buffer?

The 11 GB GDDR5X frame buffer fills before the 352-bit bus saturates in most titles. At 1480 MHz base and 1582 MHz boost, the GPU core typically reaches its ceiling before memory bandwidth becomes the bottleneck.

How loud and hot does the Black Edition run when the 3584 CUDA cores stay at 1582 MHz boost all day?

The redesigned cooler with L-shaped fins and pin-fin heatsink is built for sustained airflow. Expect typical high-end GPU thermals under full load; fan noise rises with temperature but stays within reference-class limits for this tier.
