Parallel Cooling Question

ChrisLoudon · November 18, 2023

Hi guys,

Does anyone have any advice on whether or not water cooling components in parallel is viable?

I have a setup in a Hyte Y60 which I'm planning on rebuilding with the official Hyte Corner Distro Plate.

At face value you might think, why would would I need to plumb anything in parallel? The issue I have is I managed to get a 3rd 120mm rad fitted to the rear exhaust area which plumbs in nicely between my GPU and CPU with my current pump / res combo setup but I suspect when my distro plate arrives, getting that 120mm rad plumbed in is gonna cause me a bit of a headache.

Without having the plate yet, I can't be 100% sure, but from the pics I've seen, I'm thinking the only way to do this and keep the pipe lines as clean as possible would be to run the CPU block and the 120mm rad in parallel.

Again, I don't have the plate yet so not sure what my primary challenge will be but would be good to get some advice here first.

Existing Hyte build specs are in my sig.

Cheers

C

dont really no what you mean by parallel... the rad and plate can go in any order.

as long as the pump gets fed and the cpu block is not the hiest point.

it ideal to probably go from pump to block first but with jet plates slowing down flow probably dose not matter anymore.

also not ideal to do a 90 off the pump outlet but everyone dose it.

for draining you want the valve at the bottom most point.

difficult to explain.

Instead of a pump, block and rad in series (pump out > block in > block out > rad in > rad out > back to pump in)

I'm thinking of putting a T-Piece on both the in AND out the CPU block and running straight through the CPU (or GPU) block to the rad.

I found the below link from EK so I think I've got the answer I need anyway.

Kinda counter intuitive and not the 'norm' but looks like it will work although not sure if I'll need to go down that route or not.

Will just need to see when the distro arrives.

Cheers

so what it is is spliting the water some to cpu and some to gpu letting the block control its flow.

back in the old days flow was king and evry 1lpm you got was about 1c drop in temp. but then the jet plate was a thing making it a bottle neck slowing the flow. but the jet plate improved temps anyway. can use one pump instead of 2 or more and some people even over volted there pumps. that and the presher of the water caused cracking. so a win win i guess.

For all the yrs of doing water cooling, what i do & know is this: as long as there is enough rads to cool the system your loop order matters not. I run a pump to 90 deg rotary no issues so im not sure on why it's not recommended. In terms of 2 pumps to 1 line i see no point as well, i did think of doing once tho to find out it's not a real improvement to the temps. But this is me. only thing i could think is your not using the standard G1/4 fitting & using a smaller diameter. Tho i don't see any 1 ever doing this. ive ran a system with out the jet plates as well to see, mehh more or less the same still, slightly lower temps with them on. But im no expert & only have worked on mine so i can only say what i know.
