Hi, 
I am currently running 3x PA2 in my rig, mounted in a frame ("
einbaublende "). 
But these are getting relatively hot. 
So ,my question is, is there any plan of making a waterblock for these? 
I would suggest 1 waterblock that covers 3x PA2 mounted in a frame, preferably made of cupper/delrin. 
With hope of watercooling my PA2s soon.
