parallel, halves to total flow rate, if your flow rate is 1000L/H then your only geting500 l/h on each gpu block.
Parallel will half the resitance of the waterblocks, so if you get more total flow by putting it in parallel you could benifit from it.
Otherwize, put it in series
With personall testing, gpu blocks has less resitance than a 240MM 120MM 360MM radator,
however, with a doubble thickness, which finns are hooked in parallel, water resitance is halfed, a 140,280 radator also has low resitance.
Bascally saying, if you have any 240MM 120MM 360MM radator, all of the resitance would be comming from there, flow rate would be detrimined by the most resctrive component in the loop
I have a flow meter, with 240MM radators, my flow meter moves extremly slow.
And using 280MM or a thick radator, the meter goes flying fast
