I also ordered the NZKT Kraken G10 Welshy. Already received my R9 290 but the G10 is still awaiting delivery. I hope it is here soon, i am expecting much better temps then 85-90C now. I will report back when the G10 arrives.
Very interested in this since i will be trying the same thing with my 290x! Although i will in fact be using the Kraken X60 for my GPU!Any results yet?
