Pump choice for a large loop

[TheRealBeandip]

Im trying to decide on a pump for my WIP system and Ive done the math on it but I want some input on my thoughts.

This system will be using 2 loops. One loop will contain:
1x 480mm radiator 60mm thick,
2x EK Monarch X4 Memory waterblocks,
1x EK Supremacy X99 CPU waterblock
And a tube reservoir

The other loop contains:
1x 480mm radiator 60mm thick
2x 240mm radiator 40mm thick
2x Koolance Graphics card waterblocks for Titan X
And a tube reservoir

I was thinking of using a EK-XTOP D5 Vario for each loop.

Anybody have a better pump idea for this system? or any experience with the D5/MCP655 pumps?

I dont care much about power usage, im more concerned about a quiet pump that can handle the flow rate for these loops. And without destroying my bank account. All of this is being thrown into a Phanteks Enthoo Primo, Ill be doing a build log in about a month once I get all the parts in.

The quietest you're going to get is to run one loop instead of two; put a mcp35x2 and set it to around 2000rpm.

One loop would be quieter but I dont need dead silence. And im set on dual loop, I would prefer to isolate the temperatures and I overdid the GPU loop so I can add a third Graphics card in the future. I intend to do some big overclocking on the graphics cards.

I would drop the RAM blocks from the first loop. Just make sure there is good airflow over the DIMMs and heat spreaders and you'll be fine.

 

[TheRealBeandip]

The choice to watercool the memory was more about looks than performance. Im aware memory barely even needs heat spreaders, forget watercooling.

This build was planned to be overkill watercooling and to look good, I prefer the look of the watercooled memory. Theres a bit of casemodding and custom parts going into this system so I feel its worth the added expense. Do you have a pump recommendation or experience with the one im considering?

 

[rubix_1011]

Yes, I ran a D5 vario for about 6 years. Those RAM blocks are going to introduce a lot of restriction; might want to go parallel rather than series on them.

 

[TheRealBeandip]

Didnt think about parallel flow on those. Im using it on the video cards.

How would you go about setting that loop up? I cant think of how to plumb them parallel. I planned on the loop going

Res>Pump>Ram 1>CPU>Ram 2

Each RAM block has 2 g1/4 threads. Same goes for the CPU block.

 

[rubix_1011]

I would go CPU > both RAM blocks in parallel, then back to serial.

 

[TheRealBeandip]

Ok, noted.

How would I connect the RAM blocks in parallel? I would need a splitter wouldnt I?

 

[rubix_1011]

CPU > splitter > RAM block & RAM block > splitter > reservoir

 

[TheRealBeandip]

Ok, thanks. That makes a lot of sense now.

Looks like bitspower is going to bankrupt me though. Oh well, who needs to pay the bills anyways.

 

[rubix_1011]

Watercooling is not a cheap hobby, but it could be worse, I suppose.

 

[TheRealBeandip]

We could be phase change enthusiasts. Look at it that way

Or golfers. Take your pick.
