One or Two rads??

I am now ready to start building my system and unsure on which loop to use. The first photo is using only a double rad in the front which will as i only intend to cool the CPU for now is more than adequate. But with the pump I’m using the flow out pipe has a big loop in it and as i have a spare 120 rad knocking about didn’t know whether to put that in the loop as well as not much more pipe length is needed.

What do you guys think??

Correct me if im wrong but judging from the 2nd pic you've already installed the 2nd radiator, if you have already installed it then you may as well leave it in.

If your flow looks to be poor then you can always take it out anyway.

I'm not sure on the pump flow rate but another rad would be good as more area for heat dissipation is always good

As Kemp said, another Rad will do nicely on your temps.

But you have to keep an eye on your flow. Too low can lead to drops in performance.

And the second Rad may just end up being a waste of space..

Not installed proper only placed to see how it would go. Everything in the case is just placed temp to check everything fits before i remove it all to secure all the pipe work and leak test.

It’s the Eheim 1250 = 1200LPH Will be swapped for (i think) a Laing DDC-1T Ultra with custom Top when funds permit.

I would install both rads. Your flow rate should still be fine as it's only a CPU loop.

Adding an additional 120.1 radiator (particularly the one pictured) will only affect flow by around 0.01gpm according to the figures, so will have very little impact on CPU block performance.

Changing pump from Eheim 1250 to Laing DDC3.2 with aftermarket top will cause flowrates to increase by 0.52gpm... around another 43% more flow on top of current - flowrate will increase from approx 1.21gpm at the moment (simulated) to 1.63gpm - quite a significant jump partnered by higher head pressure, which will result in better performance of CPU block and both radiators.

Its unanimous, both rads are staying. I am about to strip the system to leak test. Will let you know how i get on.

Thanks everyone for your input/advice.

Dave.
