how much flow rate is enough?

[ki8aras]

i was thinking of buying EK's phoenix kit since they're dirt cheap nowadays to replace my aging(and loud) dark rock pro 3

my question is:is the flowrate of 150L/h enough to support extra radiators and blocks in the future?

Doesn't sound like enough to me.

 

I have a DDC rated 600 L/h running at 40%. Assuming a linear level that's 240 L/h which isn't even enough to pull any trapped air out of high points. I consider 40% enough for my uses but I do turn it up occasionally.

Id rather spend more and have better performance. Flow goes a long way with multiple rads. But that also depends if you care about chasing that 3-5c difference it could yield.

1 GPM is enough. Beyond that you get diminishing returns.

 

1 GPM is about 227 LPH.

 

Minimum recommend would be 0.5 GPM, thats about 114 LPH.

 

So long as your between those two you fine.

in my case, spending more means spending about double to get the equivalent rad

How so?

if going custom, I was planning on using a d5 pump/res combo,with a ce rad, some 30 euro fans, and some fittings and about 15 euros of tubing it comes out to about 380 euros

while the EK phoenix setup only requires a 50 euro block and 140 euro rad

Ok so that isn’t the context at all. You just said it would cost more for an equivalent rad. 

 

If you dont mind turning the fans up to try and make up for the lack of flow then go the cheaper route. Simple answer, the flow isn’t good to begin with, but depends on the components and what you’re expecting to achieve.
