Furthermore, the site heard AMD had to cancel the July 27th pre-order date due to problems with Threadripper availability. It appears the retail launch volume may be rather low.
Earlier this month, the site spread a rumor that the first Threadripper processors would ship with an AIO liquid cooling kit, but it seems the site is no longer sure about that:
When it comes to the news about liquid cooling, GDM is now changing their story. There is no reference watercooling for Threadripper, at least not yet. In fact, they claim that Threadripper is not even equipped with an air-cooler. Reviewers are likely to get the first batch of brand new Noctua TR4 coolers (or other brands) with their kits, but if you were planning to buy TR, it appears that you need to ensure that your cooler is compatible first.via: VideoCardz
