not that I know 100% for sure  but the hydro's were just reference designed cards  pcb's used  .  unlike ftw or class's that are evga designed PCB's
 
theres a image from here with a swap out in progress

sad thing is  with evga is they crap can the parts specs page so you can now go look at any compatibility list  the hydro block fit on   if its not there latest stuff its a goner here at evga  -0- support  unless theres a archive page to find things  ???  good luck
 
thing with a 900 series  is that there were little to no custom water cooling for any of the aftermarket PCB cards  most all just fit reference designed PCB cards   
 
going by what little I see, seems like a match  for the swap back to air cooling 
 
your pretty much to you buy , you try and hope it don't make you cry  .
 
this part may be a issue
 
''No screws! Nothing else included, just the cooler, exactly what you see in the photos''   no screws  ??  if the ones you got don't work out your stuck  again if you cant match them up t your local hardware store  ?????
