Help needed with Aquastream XT + top "im out of options"

post #1 of 3
Thread Starter 
Hi all,

Firstly this is what i have the Aquastream XT pump and the Aquacomputer aquainlet PRO 150 reservoir see below for the entire combo:

CREATOR: gd-jpeg v1.0 (using IJG JPEG v80), quality = 95


I always do a test run outside the case for all my blocks to see if they leak and if the pump performs properly, the test consists of a cpu block, gpu block and a 480 rad.

I have a secondary watercooled pc with the same pump BUT with a seperate reservoir which performs strong no problems at all (knocking on wood)

Generally the pump gets its water from the reservoir which should be above the pump at all times no problems here in that.

So i started to test run and filled the reservoir with water but i had a thought because the inlet of the pump is connected to the radiator ie: pump - cpu - gpu - rad - pump.
I made sure the tube from the rad to the pump had water. I started the pump initial it went good till there was no water in the tube (rad to pump) even tho the reservoir was full...i know running the pump with to much air is a no go area so i stopped. I flimsy removed the tube from the rad and filled it with enough water and re attach the tube again this was better water started to flow until...well it sucked to much air from the rad the water level in the res decreased very slowly...

What kind of design is this?? i should provide the pump with water but with this design i cant also there is a limit how far i can tilt the case with the rad.

With a seperate res ( res - pump - cpu - gpu - rad - res) filling the system is very easy and fast because i can always provide the pump with water when the level starts to be to low ie about to suck air, then turn of the pump fill the res with water and repeat.

This set up is difficult am i missing something? All i could hear was lots of air being sucked i assume this pump + res/top would do the thing for me but the water keeps stationary until i removed the tube from my rad in order to fill the DAMN thing with water and this is my first time using this combo pump + res/top as shown in the first picture.

How do you guys even fill the system with a pump and reservoir combo like this:



Any help is appreciated.

I have the same pump but use a remote reservoir. Looking at the design of the res/pump. I would guess that the res is like a T-line if using the inlet at the end of the pump (recommended). First thing to suggest if you are using the end inlet is to loosen or remove one of the plugs at the top of the res as the air in the line gets to the pump. This will let the air escape and let the water into the pump. Same pretty much if plugging the end inlet and using one of the ports at the top for inlet. You will need to loosen the other top inlet to let the air out. If the air cannot get out you are in effect creating a vapor lock. You will still need to move the computer around once water is flowing to get the air to reservoir. Even laying the computer on its sides or turning upside down to accomplish the task. Hope this helps.

Thank you very much for the reply,

In the mean time i redid my test loop which is much more similar to my end build including the position of the rad, cpu etc.
Your notion of the reservoir working like a T-line has definite merit to it since i can confirm it it takes slower to "empty" the reservoir/pump combo then it would with a separate reservoir which takes 2 or 3 seconds to empty (swiftech res V2). The pump it self is powerfull and eventually it did filled the loop it took approx 6 to 8 sec to empty the res/pump combo to refill the res i turned off the pump and rinse and repeat. I assume i should not worry to much about the inlet (frontal inlet) because it would be logical that aquacomputer had this design tested but with that mind set of a seperate reservoir feeding the pump via the inlet sticks with me. I could see the inbuild res provides the pump with water albeit at a slower pace.

The one thing i dont understand once the pump is running with a full loop (there are pockets of air inside the rad which can be solved by your hints above) and seeing the air bubbles through the tubing with a strong flow...but the reservoir stays dead static no movement turbulence of water it stays stationary even tho i know the flow is strong is this a deliberate design? With other types of reservoir/pump or seperate reservoir there is much turbulence inside the res...

Anyway thanks for the help.
