WATERCOOL's Heatkiller IV for the GTX 1080 Ti is up for review at [H]ard|OCP, as you can see below it certainly adds a cool look to your card, but that is only half the story.  WATERCOOL added some features which should improve cooling, such as a flowplate as well as changes to the internals which should improve flow rate.  This results in noticeable improvements over a Founders Edition, with both lower temperatures and higher clocks.  Check out the full review to see if it convinces you to switch your cooling methods.

"Watercool and its Heatkiller series of custom water components are well known for being some of the best in the world when it comes to performance and design. We give its Heatkiller IV water block for the NVIDIA GTX 1080 Ti a good once over, and come away very impressed. Quality and performance all in one package."
