Temps throughout a loop will equalize in a matter of minutes. Most think of a loop as trying to cool the components when in reality the water is removing heat. Location in the loop does not matter because the water flowing through the block can only remove so much heat.

 

Set your loop up so it looks the cleanest and still gives you access to work on your rig when needed.

I thought the pump will contribute some heat to the fluid, won't it? Isn't it better to go from pump -> rad ->WB -> pump?? Just curious

 

Heat gains from an inline pump are so insignificant that it's not even worth worrying about. With current components just route the tubing to provide the cleanest run; just keep in mind that the res/t-line must be the last component before the pump.

 

The concept of placing the rad between the pump and the WB stems from the early DIY H2O days when people were using submersible garden pumps in a water tank acting as a res; this added heat to the water in the "res" and as such the excess heat had to be removed before using the water to cool the CPU.
