These water blocks weren't very good.  It's impossible for me to know, but I suspect that they won't make a return.
 
I suggest that you take a look at EK's waterblocks.

I recommend buying blocks with clear plexiglass tops so that you can see the microchannels inside and see that they aren't plugged up or corroding without having to periodically take the block apart just to see what you could have seen if you had purchased the version with the clear top.  Less maintenance.  Less worry.  Less taking the block apart for no reason and then risking having leaks or damaging o-rings which are hard to find.
