i can't figure out if i install my rad on top of my casing n resevoir at the 5.25" bay, so how should i get the air trapped out??? how should i refill water??? when i shut off my pc, will the water from the rad on top will flow down n fill up the reservoir???
really how should i fill up water in the first time??? hehehe... do i need to have an opening on top of the whole wc setup???
need advice...!!!
TQ...
with the rad at the top of the case, your pump will do the job of moving water up into it. try to make it possible that the rad is removable so that you can bleed the entire system of air before you mount it in.
before turning on the pump, make sure that the water level is already higher than the pump impeller. The pump cannot be run dry remember, or you'll damage it.
you don't need to worry about water flowing into the reservoir and air flowing out to the top. As long as in the reservoir, the water level is higher than the inlet, the air will remain there. With the system off, water from the radiator will not flow down and replace the air there without anything replacing it. It's a simple law. Just like when you fill up a bottle with a small opening, when you turn it upside down, water will not come out unless there is a sufficient opening to allow air in.
So basically, after assembling it the way you want, remove the rad from the top of the case, fill with water. jump start your power supply without anythin but the pump connected. watch the water level in the reservoir and keep topping up when necessary. you may need to turn off the power, fill the reservoir again and start again. As air gets removed from the loop, it goes back into the reservoir, and you have to top up water again. The part that gets stuffed with air most is the radiator, you have to turn it around according to the flow of water to move air out to the outlet. A dual pass radiator will flow into the rad at the inlet, flow down the tubes on one half of the rad, make a turn round at the plenum chamber at the end, and flow back to the outlet on the other half of the rad. (donno if that made sense i'll try to draw a diagram sometime)
here's another two suggestions. I'd prefer the one on the right though. with your diagram you have to remember the inlet and outlet directions of the pump are always at a 90 degree angle apart. so you have to take that into consideration if you want to place the reservoir at a significantly higher level because then, you have to provide sufficient space for the tubing to bend. You should never put the reservoir at a lower level than the pump however. The water level of the reservoir should always exceed the height of the pump impeller.
