Adding dual pump in single loop or dual loop on passive system

Hi, I currently have a 6800k overclocked and a 1080ti. The case is a Thermaltake level 20 XT.

I'm using 3 x 360 65mm radiators plus a phobya 400 85mm thick rad and my poor D5 pump, not surprisingly, isn't creating too much flow.

I have another D5 spare, should I just add it too the loop have way through or have 2 separate loops?

Although I have fans on the top 2 360's and a 200mm on the phobya at the front, they're set to only spin up at 60 degrees which they never reach.

I will be upgrading my system to either a new AMD 12/16 core or maybe a x299 if I can pick up a second-hand board and CPU at the right price.

Thanks for your advice.

Hi,
Usually only do a single loop if the case just can't fit two good size reservoirs in it.

There's plenty of room for my other pump/res but single loop looks like the way to go.

Tbh it's running well atm but I'm just a bit worried that once I put in the new hardware the lack of flow rate may be a problem.

Thanks all for your advice.

The lack of flow would be more from the blocks/fittings than the rads...

I'd opt (and did, lol) for the dual pump in single loop

I hope you have some kind of airflow in the room though, passive systems are tricky. I have a BUNCH of rad space and still have fans, just extremely undervolted

this hurts my head.

single loop.

as seen above, the statement that dual-pump is necessary is no longer taboo. Mostly cuz BNegative finally started using it himself, n he was one of the major folks telling everyone no.

R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.
