I don't know when it's coming, but I do not recommend getting it either tbh. I've read a review where it was one of the noisiest coolers while getting a few degrees higher than the normal skt1366 coolers like the noctua SE1366 and the TRUE. Aside from that it consumes way more power because it's using a TEC.

If you are thinking about spending this much money on a cooler, I'd go for a good WC kit like the X2O.
