I'm sure this question has been asked a few times (and probably debated to death with noone ever arriving at a concensus) but I've searched the forums under every string I could think of and found nothing, so here goes:

I'm about to build my first WC case and I'm having a hard time understanding what order all the parts connect in.

Pump > Rad > Res > CPU > GPU > Pump?
Pump > CPU > GPU > Rad > Res > Pump?
Pump > Res > CPU > GPU > Rad > Pump?
Pump > CPU > GPU > Rad > Res > Pump?

Any opinions? What's worked best for everyone else? Eventually I may end up playing around with a dual radiator idea I've been kicking around in the noggin for a little but I figure I should probably start smaller.

Thanks!
 
My setup goes
Pump > Rad > CPU > Res

I figure that the punp should draw directly from teh res so that it has the largest volume of water right before it. Other than that... threre really is no diff... so long as you keep the CPU as the first block in the order of blocks...

so...

Pump > Rad > CPU > GPU > Res

is my suggestion
 
Doesn't make a whole lot of difference. Pressure pretty much stays constant throughout the loop. You just wanna make sure it's easy for your pump to get water. And temp is close to the same. Mine only has a 1c-2c difference between water coming from block and outta the rad.

Then should the res be above the pump ideally? The whole gravity feed thing? I imagine a pump with a good "head" to push through the loop would also be able to draw as well (especially since the pressure in the line would force the water back to the pump anyway, right?) Hmmm... maybe I just answered my own question.

Yeah you got it. It makes it a whole lot easier when priming and bleeding your system too.
 
The order of components in theory doesn't really matter at all. What you want to do is arrange it so that maintenance and routing of the plumbing inside the case is the easiest. As pointed out it is a lot easier to fill a loop and prime the pump if the resevoir is located above the pump, but it is not necessary. Technically once you get your loop set up and filled/bled, since it is a closed loop the orientation of the components matters nothing.

Also there is hardly any change in temperature as the water moves throughout the loop, you will not gain any tangible performance gains by sending the water from the pump to the rad before going to a waterblock. You will get a better performance gain by making your plumbing as short and neat as possible (reducing restriction caused by longer tubing or tight bends).
 
Thanks everyone for the input... most of that is pretty much along the lines of what I was thinking but I just wanted to be certain.

One last question with a different topic (but didn't feel like starting yet another new thread)... is there any real difference between a fan pushing air through a radiator vs a fan drawing air through the radiator?

Logically it doesn't seem like there should be a difference but since I'm going to install the radiator in the top of the case as an exhaust (which, yes, I understand is not as good as drawing fresh air through the front) I'd hate to further hinder the performance. I've considered a top intake set-up but I'm not sure about that.

And before you ask why I'd to the top exaust thing when I already know it's not as good as the fresh air intake, I can't figure out how else to install a DD 2x 120mm radiator in the front of a Lian-Li PC-75. Besides... I'm still in the planning stage, anything could change with suggestions.

Thanks again!
 
Pull air through your rad for two reasons, 1. helps to eliminate the dead spot in teh middle of your fan, 2. I remember reading on this forum somewhere that it's quieter.

As for the fresh air issue.... once you remove the major heat producers from your case (by water-cooling them) the heat in the case is not gonna affect it that much.
