Default Using two 800 LPH pumps in parallel

I know a few years ago someone asked about parallel or series pumps... Difference is I'm not talking about using two laings... Im talking about using two EK DCP 4 pumps in parallel to boost the flow rate from 800.

The loop is just CPU waterblock which will be an ek block for the new AM4 ryzen 1700... I will OC the CPU as far as i can using offset voltage.

Got a 360 radiator which as i recall is a low restriction design so it doesn't load the pump too much.

Or would it be better to ditch the old ek pumps and go to the expense of a laing with up to 1500 flow rate?

😀

With a loop of just a CPU block and a rad I highly doubt you will see any performance gains by increasing flow.

Yar, I guess 800lph isnt that low is it.

You should be fine. I have a DCP 2.2 running a CPU (EK Supremacy EVO), GPU (EK Titan X FC) and 360 rad (HWLabs SR1).

I've had my EK DCP pumps for many years. No issues. I will order an EK AM4 CPU block.

another thing using dual pumps put more heat dump in the loop

better with a single pump keeping the coolest setup

parallel = more flow same head pressure

series = more head pressure same flow

Series to increase head pressure. Parallel to increase volume. Increasing the speed of the flow will not necessarily translate to lower temps as water needs time to capture heat and then cool off in the rad. Easiest way to find the right flow for your loop (they are all different) is a variable speed pump or pump controller running prime 95 at your desired overclock and tuning the pump speed to the lowest temp. You might be surprised to discover lower speeds produce lower temps.
