pump low or high up in a loop?

[cluelessgenius]

does it matter wether the pump is o the bottom of the case feeding up or at the top ?

Not really, obviously having it up high means gravity will help with the initial pumping but ultimately it's gotta pump water both up and down anyway.

alright so if cramn the pump in the back half of the o11d itd be wiser to put the psu in the top slot and the pump res combo below right?

Whatever best suits your needs because honestly it makes no difference.

Can't you put it above the der8auer plaque?

maybe. but to be honest. my build plans have changed alot over the past month even years and the pump res combo lets say...isnt as appealing to look at anymore because my stupid ass has tried painting it before. so ideally id hide it. and honestly i like the clean look without a visible pump

'Ideally' you would have the pump at the bottom and the res at the highest point, making sure the flow goes from the res to the pump directly.

 

However, so long as the res comes before the pump in loop order you can have it anywhere, the problem ull have having the pump higher than the res is priming it when filling. Once its primed though it should be fine.

well i got a pump res combo so no worries there but dont i need to have it be the highest point in order to fill and bleed it? if i put the pump/res combo at the bottom wont it overflow when trying to pump water higher than itself. ok writing this out makes it sound kind of stupid of me to think . but is it?

[SolarNova]

Bleeding is indeed easier if the bleed port, in this case the res, is the highest point, but you still going to be needing to move the whole system around to get air out of the corners and curves of the radiators and blocks anyway.

 

As for overflowing, no that wont happen. The only time the amount of liquid in the res will change is when the pump is on then turned off when there is a sizable air pocket within the loop somewhere. In this scenario when on, the level in the res will drop somewhat then when u turn it off it will rise. It is best not to fully fill a res when the pump is on until after you have made sure all air is out of the system.

well that sucks. i want my pump/ res at bottom of the case. theres really not alot of options. i could put it on the top but then it would still only be equally as high as my top rad and it would sit directly over the psu instead the other way around.

 

could not just open the top most cap of the top rad a little bit for air to come out like you would do with a apartment heater radiator?

Air bubbles always like to go up, meaning they would naturally move away from the pump if it's below. And even if there is liquid evaporation and poor maintenance, if pump is down below, it'll always get fluid one way or another. If it's up high, it might not.
