I have to say, given that it's the non-vapor-chamber version, the cooler is impressive - particularly with how low the temperatures stay with such a low fan RPM.
Then again, the article used superlatives such as massive, and brutally effective, and that pretty much is my feeling on it.
In a perfect world, I'd like to see this with the fins oriented so that the rear vents could actually be useful, allowing some of the hot air to be expelled out of the case.
This isn't the card for me, were I looking to upgrade my son's PC - as I'd need to upgrade his PSU. At 2560x1080, I think running at the lower clocks, for a better performance/watt, as was mentioned in the analysis of the Vega 56 back when the first review was done, would be what I'd go for, and take advantage of things being uber-quiet.
Eh, basically, I wouldn't need the overclocking - but I'd love a model that was price-effective, and had such an amazing cooler. Major kudos to Sapphire on the cooling front.
