Asus' ROG Strix GeForce GTX 1080 Ti 11GB OC Edition is remarkably unremarkable, aside from its snazzy RGB lighting effects. The company defines a wholly reasonable 275W power target, which should be plenty for a bit of overclocking. Even if you tune more aggressively than you should, Nvidia's voltage restrictions minimize the potential for damage. The silicon lottery will also keep you constrained to a fairly narrow overclocked range under air cooling.
A three-fan thermal solution works well in this case, though you can hear an oscillating sound at high speeds since the trio isn't exactly synced up.
It'd also be nice to see Asus employ a good VRM heat sink, which could have prevented high temperatures from building up on the PCB and ultimately heating the GPU package. For a bit of perspective, this weakness only materialized during our stress test inside of a closed case. Still, it's not exactly optimal.
Conservative fan speeds allow a wholly high-end ROG Strix GeForce GTX 1080 Ti 11GB OC Edition card to operate relatively quietly under full load, and that's quite an achievement. Manually increasing the RPM a bit helps bring temperatures down without ruining the acoustic experience, if you're really worried about heat.
