RP-452x2 setup

post #1 of 9
Thread Starter 
I plan to have 2xMCP655-b's in my RP-452x2, and I was wondering if I could go

res -> rad, cpu, gpu1, gpu2, rad -> res

is that possible? Or do I need one of these ?

or

I am 100% unsure, haha.

I think there is supposed to be a efficiency benefit to using the kit if you are going straight from P1 out to P2 in. The benefit is from the Lexan piece, the crossover pipe is just to make it tidy.
If you use the kit, I believe you are supposed to change to the short plug.

If you don't mind using a bit more tubing, you can configure the system so the pumps are in different locations in the loop, and skip the kit.

I'm using the RP-402x2 with 2x MCP35x pumps and have it going P1 out -> Rad1 -> CPU -> RAM -> P2 in -> P2 out -> GPU -> Rad2 -> P1 in.

My pumps are under individual PWM control from the graphics card and by the CPU_Fan, and often are running at different speeds, so I wanted them separated in the loop to avoid the weird noise issues from back to back DDC pumps running at different speeds.

I'm not sure if the second connector would fit, but the kit connector (first link) works well. It's not necessary if separated the pumps with a component or two, but it does minimize the tubing connections to the pump. I actually put the acrylic piece in the top/right reservoir so I could utilize the deeper left reservoir and that seemed to work fine. Took me about an hour yesterday to fill the loop to a good circulating level.

Just be aware these are not as easy to fill/prime as a separate pump/reservoir...they do take some work to fill/bleed.

I was hoping to reduce tubing, I have 2 mcp 655's.

so the first kit (with the lil area deailio) would be best? any one make a how to on how to configure it best? Which plugs to take out and whatnot?

what makes them difficult to bleed/fill?

Yes, the first kit.

How would my loop go? Where does that white thing go?

It's not bad, I can bleed one enough to use in about an hour and the rest of the tiny bubbles work themselves out in about a day or two. It just takes a fair amount of flipping the case around and using a funnel + barb to get it filled. The baffle system allows a fair amount of flow to continue on through and recycle so it takes longer than a large separate reservoir.

I've had t-lines that were more difficult, and have no problem with it. I'm really happy with the one I've had running a single pump for a few weeks now, no problems.

I would suggest the first link, not sure the other one would even work or not.
