yeah, so they discontinued the current one, looks like most of their line is being refreshed... nothing like getting an ESL customer service rep...
They should (hopefully) have the new line out in the near future... not sure on their usual new product launching timetable... could always leave the stock cooler and forego any overclock until it comes out, the stock thermal paste is pretty easy to clean off (high proof rubbing alcohol and a microfiber cloth - if you don't know how, youtube has a ton of videos showing).
