Proper flow rate?

[dhmillertime]

I have an eisstation, eisbear, eiswolf, and 560 rad. Flow meter says about 87 L/H. That seems low, doesn't it. No 90s or quick connects. The second Pic is an eisstation, water block, and 3 quick connects, shows about 50 L/H. How would someone get 1GPM if these are normal readings?

Hi As you can check in your system are both pump working against each other.You are going from the IN on the Reservoir to the IN on the Eiswolf!!. Please change the Tubing in your System so that you are going from OUT to IN. The easierst way. As I can see the same case is also in the Eisbaer. You are going from the OUT of the Eisbaer to the OUT of your reservoir.

Let me turn the system on the bench so the view is clearer, maybe confusing the way the parts are sitting. But to my question... I should expect more than 87 L/H to flow through one of alphacools systems ?

I removed the impellers from the eisbaer and eiswolf. Now, the flow has increased to about 107 L/H maximum. A 360 rad will go in the loop too, just trying to get the flow rate figured out. The eisstation was pushing 400 L/H with a straight tube loop. 25% capacity with 2 fittings doesn't seem right, does it?

Which pump are you using now?

 

[dhmillertime]

Vpp755 eisstation

That's all right. Radiator, GPU & CPU cooler make the system additionally restrictive & slow down the flow. The flow rate specifications of the pump are always given for the ideal case without disturbing factors. The flow rate for 2 coolers & a 480mm radiator is perfectly fine.

Understood. So acheiving 1gpm is a fool's errand with this pump. I removed the cpu block and get 200 L/H. I think people might be exaggerating when they say they get 1gpm or these parts aren't up to the task..oh, and thank you for the help.

You're welcome ;-)
