TechPowerUp received word that select motherboards from ASRock's 8-series motherboard lineup will be waterproof thanks to a conformal coating. This feature should come in handy to limit damage from watercooling leaks and to protect the motherboard against condensation when doing LN2 cooling.
Why do you need it? Because the enthusiast crowd likes to use water-cooling, and custom-built water-cooling loops are prone to leaks and spills, if not done right. Water-proofing ensures the board is more resilient to coolant spills. ASRock doesn't guarantee protection from all kinds of liquid coolants, but at least it's a step in the right direction. Other innovations by ASRock include enhanced onboard audio, HDMI in (for video recording), 802.11 ac WLAN, and HomeCloud software.
