Default Re: Cavitation or Airleak?

Don't have PQ charts for those components, so can't give you an estimated flow rate.
To be honest, I don't know how people resist fitting it all together outside the case and mucking about first, but as per the above, they do.

So, take it out of the case, and I'd disassemble it and do some simple flow rate testing (time how long it takes to fill a bucket). Start with the bare pump, then add the rads, then add each block in turn. The first component will always murder the flow rate so don't blame it.

Flow above 3LPM is sufficient with modern blocks.

That vid card looks like it will be to blame though. The fitting look industrial, so there may be scope to drill them out for less restriction?
