Pump pulling from CPU does it make a difference?

[NaeKuh]

How much difference does it make? Wish I saw that before filling it and bleeding it LOL I suppose I will just leave it as is now unless the difference is really significant?

i recorded around a 2-3C benifit.

honda i think also reported around a 2C benifit.

I'm interpreting this as putting the pump just before the block yield the best temperatures, and I have heard the same statement before.

Anyone have a theory to why?
As previously discussed the flow should be the same no mater what order we place the components and for all practical purpose water is incompressible, so the pressure on the inlet of the block should not really matter.
The only theory I can come up with is that you have a turbulent flow after the pump and if you place the block close enough you get turbulence at the inlet of the block for "free".

Anyone whit a better idea?

realized lately my fluid mechanics is botched..

but originally, i anticipated the increase head pressure gave better turbulance inside the block, which then increased it efficiency.

Pressure at the inlet defines how fast and how effective your accelerators are.

Pressure drop is dependent on velocity to the second power or V^2. Pressure drop increases much quicker with higher velocity.

Putting the block after the pump will result in more flow rate to the rest of the blocks downstream.
