Hey all,

I had an idea for a parallel (ish) flow loop that I would like opinions on.

Particularly whether its even possible without trapping air, or if there will even be flow through blocks etc.

This is the part where I insert a terrible graphic of the loop made with MS Paint:

(not to scale, just vague proportions - may also be misaligned somewhat)

I think the idea will work for the aesthetic I want, I am just not sure if it will actually work as a cooling solution. The arrows on the image are what I imagined the liquid would do in serial, would there actually be flow through the blocks or am I in some fairy tale land with this?

Any input would be greatly appreciated!

I'm inclined to say opposite to Jokester here, water will take the easiest route it can and with the CPU, mosfet block and rad after the gpu's id say you'd get quite good flow through both blocks but very poor flow after them.

Dont forget the pump will be pulling a negative pressure on the return side so will effectively be pulling water through the gpu blocks as well.
 
How are the GPUs actually plumbed? It looks like you've got the inlet going straight through to inlet on the next one, and same with the outlets. Thinking about it more Danm54 is right, the water flow will just go through the bottom GPU and back to the pump as a preference as the path of least resistance, the flow through the CPU block will be greatly diminished.
 
Thanks for the responses guys, I was afraid the CPU wouldn't get enough flow with this. To prevent that the GPUs have to terminate and not passthrough right?

Then the CPU, MOSFET, possibly ram and rad have to be serial later (or earlier) in the loop... Hmm, will need to think how to best route that.

Any ideas you guys have to fix it are welcome too!

Just go from the cpu to the res. Job done.

I thought about doing that, but the RAM would be in the way of a clean route to the res (trying to avoid loopy bits as much as possible). If I put a RAM block there it would be justifiable though, hmm.

For the radiators in the basement, plumbing them like the below (crude) image would yield the best flow rates and work perfectly right?

Again you'll be better and neater putting them in series.

If they offer the same resistance then you'll halve the flow through each rad, so the water will spend twice as long in the rad but will only go through one!

If you had really restrictive rads then it would benefit as you'll give the water more routes to go. As they're not the most restrictive part of your loop then put them in series, you'll see better performance.
 
You are right about the rads being wasted like that, totally wasn't thinking this morning haha

Well thanks for the pointers here guys, I need a total rethink if I'm going to try and go for parallel flow!
