water cooling configuration question

[safemode]

Ok, the question is this. Most people have their system set up pump -> cpu and other blocks -> radiator -> resevoir (if they use one) -> pump And that's all well and good. I was wondering why they dont do pump -> radiator -> blocks -> pump. The added heat from the pump instead of being sent with the water to the cpu block would be combined with the heat from the blocks and then sent to the radiator, where they would be cooled before reaching the block again. This would guarantee the the water being as cooled as possible before reaching the blocks and it would be the most efficient setup. I'm just wondering why nobody I've seen does this ?

i agree with u the only thing is i think moist people already do pump >rad>cpu>etc... :D :eh?: :D

pump to rad is the way i do things, too.

A lot of times you will get better temps going pump>block>rad.
It depends on your setup. The reason is that you get the greatest flow rate to the block right from the pump. This would hold especially true to those that use a res. In a true inline system (no Res, air tight) this is somewhat not the case as the water would be flowing at a constant rate at any given point in the system.

most people do do it this way already? Whenever i've seen pictures of setups it always looked like hose branched off from the pump at the bottom of the pc traveled through the blacks to the top of the pc where the radiator was (usually) and then back down to the resevoir and pump.

Also, is there any data to back up the assumption that placing gravity before or after the power head matters at all with the flow rate? I mean to say is does it affect the flow rate of a closed loop system if the pump is on top next to the radiator for instance or if it's at the bottom and the radiator at the top? Logic forces one to say that it doesn't matter in a closed loop system because the net force is the same.

In an open loop gravity behind the head is not as efficient since you would rather not have to push water for the entire way back down (gravity does that work for you).

I suspect closed loop systems it would only be a matter of taste.

I plan on encasing the pump maxi-jet 1000 I suppose in an air tight resevoir... I dont want to have evaporation issues or water contamination

I'd like to get away with using the least amount of additives to distilled water.

that and I want to constant flow rate.

I saw this one pump kit or so that had inline 1/4" bleeding valves. Does anyone know where i can pick these up ? I plan on sealing all the connections so removing connections for filling would be a bad thing.
