Specs and pictures below – can you advise which of the two would be most efficient, or if you have an even better idea. (GFX card may be included at a later date).

Specs:

Pump: Swiftech MCP655 w/ EK-D5 X-TOP Rev.2
Rad: XSPC RX360 Radiator
Res: EK Multioption 250 Rev.2
CPU Block: Heatkiller 3.0

Option A

Option B

Thanks :)
 
Efficient in what sense? Where are you putting fill/drain lines if using either. Have you read [thread=18110822]this[/thread] thread?

I wasn't going to use either originally, but I might I don't know. As for "efficient" I simply mean which option will allow for the best flow/cooling. For example having the rad connected directly to the CPU block so the liquid is the coolest before it hits the block etc.

But after reading your above thread I'll be looking at possibly putting a t-line going from the top inlet of the Res... But then again the top inlet is the best inlet to use in the loop for that Res - this is why I asked for advice ;).

EDIT: changed 'rad' to 'res' - sorry for mistake.

In that case I would choose one similar to A, except with the reservoir turned the other way up.

One line goes cpu block to radiator, another from radiator to the top center input of the newly inverted reservoir. Run a fill line into one of the side holes near the top. Connect the pump intake to the center bottom hole of the reservoir.

Remove any antiturbulence plates or whatever else ek is currently putting inside their multioption reservoirs, and aim to keep the reservoir pretty close to full all the time (I'd have the fill line half full). Unsure if it's possible, but if it is I'd also screw a barb into the inside of the reservoir, at top center, to give a space for air to collect in.

Whether you do this or not is entirely up to you, it's just how I'd lay it out.
 
It should make no difference after about half an hour or so, as the temperature balances out. But as a general rule of thumb:

Pump>CPU Block>Rad>Res>Pump
 
Very good suggestion... However the EK anti-vortex plate you could call it, is melted into the res itself - removing it would wreck the res. So that's a no-go. :( Any other ideas? Appreciate the help btw.

EDIT - Also turning the res upside down with one inlet at the bottom would act as a drain, causing a vortex within the res.

I've heard this many times before, but is there any reason this is the "general rule"? Thanks :)

Well the reasoning is that the cool water gets to the CPU and takes the heat away to the rad where it can be dissipated, then it gets to 'rest' and loose a bit more heat in the res before going round again.

Fair enough, seems like most configurations would end up with the same performance though? So I guess it's more about general layout for ease.
 
Regarding a vortex forming in the res, that's why you keep it full.

Regarding the heatkiller, water in the centre out at the edge is the intended way round. I used an ek supreme (similar internals) with the steel plate removed and the water flowing the wrong way and still got 60 degrees load at 4ghz, so I'm not sure it matters very much.

Sorry I don't understand what you mean by the inlet/outlet description - could you clarify :)
 
Which bit? That you should pump water into the middle of the block and out the edge, but if you do it backwards it won't matter all that much, or my suggestion for the reservoir?

If the latter, the ek multioption has a hole in the centre of each and and two additional adjacent holes at one end. I think you want water going in the top centre and coming out of the bottom centre hole. I'd put a T line running to a side intake near the top of the case to aid filling.

The heatkiller, dw it's clear now :).

I think I may try to set it up like this

If I can... lol
 
In the modern day with non-impingement blocks and flow rate being a low factor in performance, the loop order is pretty insignificant. More important to keep the loop as short as possible.

In fact Vapor shows here that rad before CPU block can potentially be more efficient assuming you aren't loosing a massive amount of flow going through a restrictive rad first.

Is your loop setup with GFX first?

It is a possibility as I havent decided even what GFX card to get yet.
 
I have just gone through the hassle of changing my loop order from:

Reservoir > Pump > GPU > CPU > Radiator > Reservoir

to:

Reservoir > Pump > Radiator > CPU > GPU > Reservoir

...and to be honest there is very little difference.

It does however look a lot neater as it was my 2nd time and I had a better idea of what I was doing.
 
I've decided to opt for option A. It seems the easiest and most logical method without overcomplicating the issue of tubes running everywhere.

Plus I figured if I want to drain the system I will just unscrew the bottom fitting on the reservoir, just hold a cup underneath it and let it drain :).
