Just installed the second card. Not the cleanest looking build but it does it's job.
First card I purchased (Gigabyte) has a 73% asic and stock boosts to 1189mhz
The second one (Zotac) is a 65.9% asic and boosts to 1154mhz.
Pretty good experience on these cards for SLI on ref coolers, 39c/36c on desktop, 2-3 loops of firestrike ultra 4k on stock fan profile hits 83c/79c with custom fan profile (~70% max) its around the 76c/71c mark.
First run all stock 1154mhz - 7243 -
