Upgrade eisblock 2 and eisbaer to custom loop

[upgrade]

Hello.

I have an eiswolf 2 for a gigabyte rtx 4090 and an eisbaer pro rgb. They each have a dc lt 2 pump.

Eiswolf 2 part:
13477 Alphacool Eiswolf 2 AIO - 360mm RTX 4090 Aorus Master - Gaming mit Backplate

Eisbaer part:
Alphacool Eisbaer Pro Aurora 280 CPU

I have an eisball reservoir with a d5 vpp755. I want to remove the dc lt 2 pumps, but keep as much of the system and add another radiator. I doubt i can remove the dc lt 2 from the eisbaer, so I'll need a new cpu block, but can i take the dc lt 2 from the eiswolf 2 and replace it with a eisblock aurora terminal?

Id like to keep the 360mm and 280mm radiator, the quick disconnects because they are easy , and the gpu block.

I want to increase the flow rate in the system and the cooling capacity with another thicker radiator. The issue is that adding a d5 to the two dc lt 2 will not increase the flow rate, but does increase the head pressure. I don't need the increase in head pressure, but i do need the increase in flow rate for my 9950x. I don't want to buy another block for my gpu and would like to reuse the eisbaer (i doubt i can).

Any help would be appreciated. The goal is increased flow rate with minimal money spent.

Currently, i have the eisbaer > 280 > eisball > eiswolf 2 > 360 > eisbaer. I had to set the vpp755 to low speed with dc lt 2 maxed out. Id like to remove the dc lt 2 and increase the speed on the vpp755 to get closer to ideal flow rate.

Why do you think adding a D5 pump wouldn’t increase the flow rate? I think you’re misunderstanding a few things here. The higher the pressure, the higher the flow rate. If you increase the pressure, you’ll also get more flow. The D5 will simply push the water faster through the DC-LTs—they’ll just get overdriven. Basically, you don’t need to do anything other than install the Eisball with the VPP pump. That will give you everything you’re looking for.

Based on engineering blogs related to pumps, the addition of a second pump only adds pressure, but flow is limited by the maximum capacity of the smaller pump.

Also, if the increased pressure overdrives the smaller pump, would that not prematurely wear out the smaller pump? It would be driven beyond the designed speed of the system shortening the life of the pump. In that scenario, given that these pumps are in series, it would cause a partial to full blockage and possibly damage components through heat building up.

I'm not seeing the speed of sensor read higher on the dc lt 2. This implies that flow rate is not increasing.

I guess this could be tested with a flow rate sensor.
