Sooo...
It's been long time coming and I always wanted to WC my PC :)
Finally I have the resources and the kit to do it :)

Let's start with the system spec:
2500K @4.8GHz
MSI 6950 Frzr III
650D case

What I would like to put in here:
XSPC Raystorm on CPU
XSPC Raystorm on GPU
SR-1 240 rad on top of the case + 2x GT15
Phobya 200 rad in fronm of the case +1x Spectre Pro 200 (or 230 if I will want moooar powr :) )
Koolance 450 pump (D5 Vario)
Koolance 450 top

Now... As I'm completely new to WC I am not sure how to get best efficiency from the system.

The plan was to have: Top rad -> Front rad -> Res -> pump -> GPU -> CPU setup.
Could this be more efficient: Top rad -> Res -> pump -> Front rad -> GPU -> CPU

Does any1 know if the d5 Vario works better in one orientation? (Koolance top can have the res added, whereby the pump is in vertical orientation).

Does it matter if for the front rad I have the ports on the bottom or top?

Does the pump have to be below the rads? Will it improve efficiency?

I'll draw up the plan and current setup when I get home - gotta take the pic first :)

I want to get a yellow/black/gray theme in and wonder if Mayhem Pastel in Yellow would be a good idea (will it clog up the system fast?)
What tubing (quality, clear, no uv) should I be looking at?
Anything else I might need?

Thanks!
 
Managed to get the layout drawn up.

A little legend ;)
Yellow - Koolance res/top/d5 vario pump combo
Red - GPU/CPU blocks
Blue - rads
Green - fans
Red rectangles (small) - outlet ports
Orange rectangles (small) - inlet ports

I thought about using 30deg connectors + compression fittings (to get better flow than on 90deg elbows) on CPU out, GPU in& out, Pump in & out, Front rad in but don't know if this won't be an overkill... would also bankrupt on the fittings lol ;)
 
Hmmm.. point taken.
Wouldn't the GPU temp be lower than CPU one?

I know that the tubes bend but which clear one is good to go for (1/2" fittings)?

I am also wondering about not using the Koolance combo (only pump as it has RPM readout) and get a nice res and a different top (which one?)
I'm worried about the way the combo would be positioned (ports towards the open side of the case) as it introduces unnecessary bends.

Wouldn't reversing the flow in this setup (as per picture) be worse in terms of flow? pump would have higher restriction parts (rads) than in the clockwise setup? Would it make a difference or the system will reach equilibrium anyway ?
 
So.. what do you think about the revised spec:
XSPC Raystorm on CPU
XSPC Raystorm on GPU
SR-1 240 rad on top of the case + 2x GT15
Phobya 200 rad in fronm of the case +1x Spectre Pro 200 (or 230 if I will want moooar powr )
Alphacool 655 D5 Vario
EK D5 X-Top V2 Top
Feser 1 UV Yellow Fluid

Now... I need to make up my mind about the res ;)
Bitspower Z-Multi 150mm or Phobya Balancer 150...

What does this plate in Phobya Balancer do?

If I go for Koolance 1/2" fittings I have two options - 19mm and 16mm, what would be a better size tubing for flexibility without kinking - thinner 16mm?? How stiff is 19mm with 3mm wall?

Let's try to work it out...
typical GPU block - let's assume 20ml of water capacity
typical CPU block - ~30ml capacity
minimum recommended flow ~1Gpm = 3.7Lpm = 61ml/sec (I assumed US gallon as it's smaller and this is the worst case scenario)

So in theory GPU block would see 'new' water 3 time every second. Even if we assume silly block capacities we would get pretty good flow so I recon the water reaches equilibrium pretty quickly...

If anyone wants to sponsor me some in-line temp sensors I can play with the setup :D
 
Guys,
I'd like to order the bits before TWO end so can you help me out with a few remaining things?

I know what brand of tubing to get but there is a choice of 1/2"x 19mm or 16mm fittings.
I guess the thinner wall the more prone to kinking the tubing is. Isn't the 19mm tubing to stiff though?
What the best combination is?

How much fluid should I buy anyway :)??
