Can you have TOO powerful a pump?

post #1 of 30
Thread Starter 
I'm planning on building a loop right now and what I'm thinking of doing is getting a 3x120 rad for a cpu loop then once I can find one on the cheap I'm going to use a civic radiator and do a dual gpu and cpu loop with it.

However for the civic rad I'm planning on using a 1500g/h pump, but I'd like to save money by only purchasing the big arse pump. Could the 3x120 cpu loop handle it, or would it just explode?

Too much turbulence in the reservoir could cause air bubbles, but I don't think you should have much of a problem.

Check the pressure output of the pump.

pressure would end up being the biggest problem you would encounter, not flow rate. The D5 puts out 50PSI and loops hold together with three of those things.

not sure, but a 750/gph pump I was looking at puts out 55psi

So I would assume the 1500g/p would be somewhere between 75-100

Also have to make sure the tubing supports the PSI of the water throughput. I would imagine with a pump that is too powerful you could also develop some leaks where the tubes clamp onto the barbs, if you do not have good clamps watch out!

I would worry that if the pump is too powerful and the connections too loose you could literally blow a hose right off the barb. If you make your connections correctly with the correct size hose/barbs that shouldn't be an issue though.

^I have thought about that, I think 1/2 should be big enough. I'm planning on doing a 48hour stress test to make sure every thing is perfect, because it is pretty risky using such an odd assortment of parts like this.

+1 on worm drive clamps..

I would get 1/2 barbs with 7/16 tubing to make a nice seal, and clamp them with worm drive clamps...
