Hi i'm new to water cooling and i'm not sure how to set dual GPU blocks on my system. I'm using 2 Radeon X1900XTX in crossfire mode

I'v picked out these 2 GPU blocks and want to know which one will be better for dual video cards and how to install them

SwiftTech MCW60

The Danger Den ATI-X18

also if anyone could recommend a good CPU block and chipset water block for the A8R32-MVP motherboard,thanks

_Floyd_

any ideas anybody?

Do you mean you dont know how the tubing should go, or how they should be mounted or how it flows??

If it were me and I had to really hot running cards I would not have the output from one card going to input of the other without cooling the water or letting it passively cool (like in the reservoir).

Now there's more information we need, like: Is this only for the GPU's, or do you have a complete setup (CPU, GPU, Chipset)

if your just asking about the blocks, I would say that the danger den block will perform better, but its a LOT more expensive. I dont believe the swiftech actively cools the ram, meaning you would need some heatsinks on them to keep them cool. However, it doesn't seem like your really hurting in the financial dept. so just get those DD blocks.

I want to know how the tubing would and how they should be mounted and all that and the whole setup is the 2 GPU blocks and a CPU block with a chipset block, i'm thinking of going with what SwiftTech has to offer for all the parts

the Siftech blocks are a little cheaper.

I would look to it like this since you are going to be using 2 x1900xt's which run fairly hot

CPU Block -> GPU#1 Block -> Radiator -> GPU#2 Block -> Chipset -> Pump -> Reservoir -> (CPU Block)

It really all depends on where your radiator is located. If you have it mounted on the back outside. you could also have the Radiator coming right after the CPU block then going to both GPUs,

This would probably be the best setup if I were doing it and had a load of cash

Pump -> Res -> SingleRAD -> CPU Block -> DualRAD -> GPU#1 -> GPU#2 -> Chipset -> (Pump)

You're going to need a high power pump since you're probbably going through a bunch of blocks and possibly 2 Radiators

If I recall correctly the water will reach a certain temp and be that temp all over, i.e. water in one part of the loop will be the same temp as another part.

busa

Not exactly....The water temp will vary slightly thruout the system....the cpu/gpu/chipset temps will stabilize at some point and maintain those temps.

Look into this resivior to give you a multi loop setup to seperate the flow from different parts of the system. You could use 1 output with a splitter for the sli cards and the other outlet for the cpu/chipset loop.

I believe you're both right. Temps will stabilize, with only small variations around the loop--the difference in temp between a waterblock's input and output will be around 2C max, and probably more like 0.5C.

Personally, I'd rather have a 2C temp differential than worry about the extra complexity (and leak potential) of splitters. Some GPU coolers are designed in mirror imaged pairs for SLI, so they can be hooked up neatly in series. I'd just go with that, and concentrate on getting a nice big radiator (double size minimum, maybe triple or more) More radiator will bring down your temps a lot more than plumbing changes!

Mr-P

Wich pump would you suggest i'm newb to watercooling and i'm looking for a similar setup. 2x radiator, Cpu and 2x GPU... but I really don't know wich pump to get. does 400L/H will be enough....?
