Water pressure

Samstag, 15. September 2012, 13:41

I have a double water cooling system. Both using Aquastream connected to Aquaero 5. The first one going to the CPU block and then splitting into 2 both with a flow sensor where one (1) goes to the 2 HDD blocks and the other to the Aquaero cooling block (2). After that they meet and goes to the radiator. The other going to the 2 GPU blocks (GTX590) splitting into 2 both with a flow sensor where one goes to the first memory bank block and into the cmos block (3) the other goes into the other memory bank block and then to the X79 (4), after that they meet and goes into the other radiator. At the moment I only have 1 graphics card, the other has been returned for garanti, so the one going to the X79 doesn't do trough the GPU first.
1 flow is around 40 l/h, 2 is around 50 l/h, 3 is around 60 l/h and 4 is around 70 l/h. The Aquastreams are both set manualy to 74Hz (max). When I had the GPU blocks in series, the water pressure was around 30 l/h.
My question is: Is the water block for the CPU (Apogee HD Black http://www.swiftech.com/apogeehd.aspx) with 1 input and 3 outputs (one is used for a temp sensor) too much for the Aquastream? The series connection of the GPU's was trough the Aquacomputer TwinConnect (http://shop.aquacomputer.de/product_info…roducts_id=2495), and this was obviously too much (I had to remove it anyway, since the Rampage IV Extreme doesn't suport 2 16X side by side. But I find it strange that a Aquastream can't keep the pressure trough a TwinConnect that is made by the same company.

Water takes the easy route.
When the flow of one pump is split, the water takes the path of least resistance. The aqua Computer graphics cards are known to be excellant at cooling, but they are reputed to be more flow resistant than some others.
I cannot for the life of me figure out what the heck you are talking about, but I think you are saying that when you have two grphics cards installed in your system, the flow through that GPU loop goes down so much that the cards over heat?
Get a ball valve and install it in the other side of the graphics card loop, and start to close it little by little until you get enough flow through the graphics cards. Total flow in that loop will go down, but you will get the water where it is needed.

There MUST be something wrong in that loop. That is absolutely no problem for the aquastream. Maybe something blocks the flow (gunk in CPU block?) or you have configured the headless screw inside the twinConnect the wrong way.

I have 4 valves, one after each flow meter and now have 60 l/h on one and 64 l/h on the other going trough the graphics card, the ones going trough the CPU cooler are 43 l/h each. The thing I was talking about is the twinconnect that sends the water trough 2 graphics cards in series. Thats a bad idea as the flow almost stops, when I put them in paralell the water stream increased dramatically. But I wonder, shouldn't the Aquastreams be able to give a higher pressure than 60 - 70 l/h? I have checked around, and don't find any pumps that gives more than 4.2 meter which is what the Aquastream gives.
