Thoughts on loop order?

[VSG]

Excuse my absence of actual pictures for a minute here (my camera sensor is on its annual cleaning/maintenance). In the meantime, could I get opinions on these proposed loops:

Loop 1 (Res->pump->Rad 1->Rad 2->MoBo->CPU->GPU->Res): 

Loop 2 (Res->pump->Rad 1->Rad 2->CPU->GPU->Res): 

Loop 3 (Res->pump->CPU->MoBo->Rad 2->GPU->Rad 1->Res): 

Loop 4 (Res->pump->CPU->Rad 2->GPU->Rad 1->Res): 


The pump is behind rad 1.

Loops 1 and 3 are the major changes, loops 2 and 4 are just omissions of cooling the motherboard (undecided yet, will be getting the EK blocks for the M6F if I decide to do so). Now, loop 1 (and 2 accordingly) will be the cleanest runs but this will involve rad->rad and CPU->dual GPU. Also the CPU to GPU connection might be tight once my koolance QDCs get here (not a deal breaker of course, I got plenty of angle adapters). Loop 3/4 will not be easy to route but makes sense thermodynamically. Note that I can't turn around rad 2 because my 5 1/2" bays will be pretty much occupied. I also have both rads on intake if that changes anything.

Any thoughts will be appreciated.

I would go with the second loop, much cleaner, no tight bends.

Its also straight forward, what I like

 

EDIT: Have just seen you want to cool you mobo, If you want your mobo in there, do #1 Else the #2

[Altecice]

two for sure yeah

[VSG]

Does it matter if the "hot coolant" enters the pump? I imagine it would only be a few degree centigrades above the mean loop temperature but anyone know if this can influence the life of the pump?

 

Also, the GPU will be getting the "hot" out-take from the CPU block. I definitely would prefer Loop 1/2 for design but wanted to be sure it won't really bite my overclocking potential.

[Altecice]

no hot coolant wont affect the pumps life. and it wont effect the temps if its going through two rads before it reaches anything

[Kukielka]

The peak and the lowest temp in a coolant will be off by about 1-2 °C, you have to look at it as a whole

What case is this?

[VSG]

Corsair 900D, I have an XSPC AX480 on top and an Alphacool Monsta 480 on the bottom. The CPU is an i7-4770k with a Koolance 380I block. The reservoir is a 400mm FrozenQ Liquid Fusion V-series cylinder and the pump is a Swiftech MCP35x on its heatsink (behind the monsta rad in the bottom).

Loop order makes no difference,choose the order with the least amount of tubing.

[VSG]

Loop 1 (or 2) it is then! Thanks a bunch, lads.

[Spannerhands]

Correct loop order, res/pump/whatever/res

[VSG]

lol that's true for all the above options

[VSG]

Update: I went with Loop 3 with an additional southbridge block as well.

Now I just need my reservoir and a few other small fittings to arrive.
