Asus ROG Poseidon GeForce GTX 1080 Ti 11GB Platinum Edition Review

The concept is simple (at least on paper): lay down a flat heat pipe on a large sink and, as an option, send water through to dissipate thermal energy from a flagship-class GPU. By adding water-cooling, you can either complement a capable heat sink and fan solution or replace it entirely.
It's certainly possible that such a hybrid may work quite well. There's no denying that Asus designed its ROG Poseidon GeForce GTX 1080 Ti 11GB Platinum Edition for flexibility though, so its performance, especially when it comes to water-cooling, does have its limits.

Since the actual performance of any third-party card depends on the GPU Boost frequency it can sustain, and thus on cooling, power limits, and processor quality, any review that relies on bar charts is little more than a snapshot of a single specimen. That's why we're putting our emphasis on the actual implementation of each model. To that end, a lot of equipment goes into thoroughly documenting a graphics card's behaviors. If you'd like a peek at what goes into such an evaluation, check out our Nvidia GeForce GTX 1080 Ti 11GB Review. It makes for a good baseline on which Asus builds.
