Using my recommended method, you will get the most effective temps possible. I’ll provide you with several scenarios, so match your setup to the scenario I list.
Pump > Radiator > CPU Block > T-line/Reservoir > Pump
Pump > Radiator > CPU Block > GPU Block > T-line/Reservoir > Pump
Pump > Radiator > CPU Block > Chipset Block > T-line/Reservoir > Pump
Pump > Radiator > CPU Block > Chipset Block > GPU Block > T-line/Reservoir > Pump

Why would these ways you list perform better ?

And how much better then if I put it.. pump / cpu block /gpu block / rad

I think i can answer that one!
Setting up pump to CPU block can add access heat to your CPU block, for i have noticed the the pump puts off heat into water for working so hard.
As for the pump to radiator to CPU. This gives the water time to cool before entering the CPU block.

Ok I ask the question only because factually no matter how loop is set up the temp differences can't exceede 0.05c in the loop.

By setting it up as this stickie suggest you can actually get higher temps if you are forced to use more tubing to acheive that specific set up sequence or if it causes more tubing bends which would slow the water flow.

When people say putting the rad after pump lowers temps I doubt there really thinking it through,because the idea although on the surface makes sense it leaves out a criticle factor.

The water is in constant motion,It never stops,and depends completly on motion to be effective.There is such a tiny measurable difference in water temp when water flows past cpu block to gpu block that it would take lab quality equipment to measure the increase.Lets take an example you can test your self.

Take a candle and move your palm over it fast then do the same only move hand slow.OR better yet stop totally over the flame for a second.You will feel in the latter 2 instances a increase in temps however when you move it fast over the flame you will feel little or no change in heat applied to your hand,NOW do all 3 experiments over and over again..notice the faster you move your hand how long it takes to get it to feel unacceptable hot.This is the principle on how water in a closed loop works..Now add a rad and the water moving fastest picks up the same heat as the slow water but it displaces it faster because each water molicule is in rad more often because of the higher flow.

Now I suggest if setting the system up provides LESS tubing and LESS bends in tubing by following the suggetions in his stickie then do it.However if putting rad before pump as its inlet supply results in a better tubing arrrangment do it that way because the chance you may get a 0.05c lower temp will have 100% Zero effect on systems ability to overclock and your ability to measure that miniscule amount of difference.

That would be why i said i think i can!
Good point

when running a peltier there is definately a difference in the way you have your loop set up and a very noticable difference in the inlet and outlet temps of the water block, this does not apply as much when not using the peltier cooling method.

Read that carefully it proves flow is a more important factor then placement of components.

I have made this point several times in other threads,,Because unless setting it up as this stickie suggests improves flow it is not something people should make important.Ease of tubing , least bends,lest total length is extreamly important,,Even in a pelted rig..

Hey Burn,

Thanks for your helpful guide!

I'm wondering how you'd recommend powering the pump when the entire system is not up and running? The paper clip in the power supply connector trick? EDIT: Short pin 14 to pin 15, as in the following photo (sorry, newbie and too tired to embed the link) http://www.7volts.com/P1010918.JPG

Thanks again!

Burn

That works for me, I've done that trick every time I filled and bleeded. I usually make sure (when I had a T-line) that it was filled to the top when powering the pump on. Make sure the pump is flooded as well, you don't want to run it dry.

Updated with pictures from the TechStation that illustrate my points a bit better. Enjoy!

your hand dun feel pain when you move fast becoz it takes time to transfer the single from your hand to your brain.
