ASUS has just announced the latest cooling kits for their current X399 motherboards which will allow full overclocking support of the upcoming 2nd Generation Ryzen Threadripper processors. The new cooling kits would be sold separately and would feature compatibility with all existing ASUS X399 motherboards.

Featuring support on the existing ASUS X399 motherboard lineup which includes the ROG Zenith Extreme, ROG STRIX X399-E, and PRIME X399-A, the new cooling kits will be available with the 2nd Generation Ryzen Threadripper WX series launch in mid of August. The cooling kits will not go out as a bundle but would have to be bought separately.
