Hi all,

Im starting my first custom loop soon, and I have a quick question on the feasibility of running a loop in parallel.  Okay, so I am building in the Lian-Li PC-09, with a Ryzen 1800X and Asus 1080Ti Strix, with two 360mm rads (Im sure thats overkill, but I wanted to fill out the case.)  Im using a D5 pump and two EK 360mm PE rads. If I were to run the loop in the following flow order, do you think the pump would be able to keep up?  Id like to run the loop from the pump/res into the gpu then cpu monoblock then back into the gpu, then into the top rad, then side rad, then back into the res.  Does that seem like it would be able to work properly?  Any advice is greatly appreciated! Thank you!

Pump should be fine, common build. Doing it with mine but with a single 360 60mm rad. Gonna ad a 420 though.

Putting your blocks in parallel reduces restriction in your loop. The flow will be divided between the GPU and CPU block.

Liquids will always follow the path (block) with the least restriction, so you might end up having one of your blocks receiving less flow that the other.

Don't worry about it to much. Unless one of the blocks can't be bleeded properly as it is lacking flow there shouldn't be any problem running a parallel configuration.

 

The D5 is an excellent pump and should do the job. I'm running 2 GPU's and one CPU in parallel with 2 DDC pumps in series which have about 2/3 of the flow rate of a D5 pump.

Thanks everyone for replying!  I feel much more confident in this setup now!  Cheers!
