Calculate How Many Radiators/Blocks Per Pump?

[MiRai]

I have an XSPC D5 Photon 170 and right now it's pushing through a single Hardware Labs Black Ice SR2 360mm radiator, as well as a Water Cool Heatkiller IV Pro. I'd like to add three GPU water blocks and either a 360x3 (120x9) or 420x3 (140x9) radiator to help keep the GPUs cool.

Realistically, can the pump I currently have handle all of this or am I going to need a second pump?

EDIT: Also, how does one calculate how many blocks/radiators a single pump can handle? What specs can one look at to figure this out?

You essentially look at the restriction of one item, and sum them up to get a curve of your total restriction. The restriction is a curve and not a number (IE, your pressure drop is higher at high flow rates), so summing them can be a bit of a PITA. You then compare that to the pressure/flow rate curve of your pump to find the max flow rate you'd see in your loop.
The SR2 is a really low restriction rad, so that's good. No idea on the MoRa.

With three GPU blocks and a CPU block, I would probably be looking at a dual D5 system if for no other reason than to help purge air out of all that equipment. Unfortunately there's not really a great rule of thumb, since the restriction of different components can vary wildly. Five of your SR2 rads in series could have lower restriction than some high restriction 360 rads.

Thanks. My water cooling situation seems like such a mess at this current point in time, and all of my options seem less than ideal.

what u think you can build that murderbox look at the fist attempt?

if it makes you feel any better, i still require a lot of time to make those setups...


i would probably go dual pumps with all that eq, and also for the added security of redundancy.

Well if it was my build.. and u want help...
I would honestly go 4 pumps split the loop into 2.
I would put the gpu's on one loop, and cpu on the other.

Since 99% of all gpu's are voltage limited in regards, you really dont need to keep then that cool, because after a certain point it will be too costly / no gained benfit, so after a certain point you can work on bling or noise reduction, because u already capped the performance side.

But that is just me, and some will say i favor multi loops too much.
