How to get/buy/whatever a Fury X pump replacement?

The pump in my Fury X kinda screwed up after it sucked in some air from the radiator.

 

First there was a noise when card is getting hot (like soft t-r-r-r-r-r). Now that noise is always there when idle, and when card is getting hotter, the noise getting worse. So I'm not into waiting till it fail completely.

 

The problem is I cannot find a way to find/order/buy any replacement part or at least some third party's AIO cooling solution.

 

So is there a way to actually get a new waterblock?
