i currently have my system set up on a single loop with cpu and two nexxos gpx ati coolers, now, i have been aware of the restriction in these blocks but something seems to be causing even more of a restriction or posibly a back-flow pressure problem. here is the current setup.
1x xspc led ring cpu cooler
1x ek 420 rad for cpu
1x mcp655-b pump (~317gph)
2x nexxos gpx ati coolers with crossfire cooling bridge( high restriction point)[ whitepaper says 4.5psi back-flow pressure is posible and could be problem]
1x xspc 240 rad for video cards
aparently, the mcp655-b has a max pressure of 50psi (1200 lph) i would have thought that one of the pumps should be enough but when the liquid gets to the cards, it only trickles down to the cards and then opens back up to fill the tubing afterward therefore the flow is hindered somewhere. but i can't seem to find the culpret.
the liquid travels fine to the cpu and 420 rad but slows to a trickle afterward then after the video cards, as long as there is enough fluid it fills the second rad without issue and back to the res.
so the question becomes, would i need to add a second pump in series to make up for the 9psi back-flow pressure? or just take the video card off the main loop and do a second loop, i realize that doing a second loop is preffered in most cases to keep the temps seperate and having better deltas but from my understanding, you technically might loose a degree or so having one loop but your total efficiency with one loop is better.
any ideas?
thanks in advance
Update: so adding a second mcp655-b in series seems to have solved the problem for now. Now I just have to watch the temperatures.
