Leak testing, now a few questions

post #1 of 6
Thread Starter 
Hey everyone,

I got my watercooling up and leak testing. Now I have a few questions:

First off, in my RES it seems like there is a little formation of foam. It seems to be from the zerex that I added. Should these go away after the system has been running for a while or is this a sign of adding too much coolant?

Secondly my fans are rated for 75cfm but they are definately aren't running at that. They are doing half that maybe. Is there a way to mix this? They aren't hooked up to a fan controller or anything, just to the PSU that I jumped to leak test.

I have attached some pics to show you.

Foam problem cleared up, it just needed to be running for a while longer. But does anyone know how the fix my slow fan problem? They are probably only blowing 30-40 CFM which is going to make a big difference on temps. Is it some sort of voltage problem? If so it isn't with my PSU because its running fine.

Anyone?

One is connected to the other, then to a molex. Could this be the cause of the 50% performance loss?

EDIT** No dice, I connected them to separate plugs and they still are running slower then they should...

Chances are, that they are low pressure fans and the HC is putting a lot of resistance to the air flow. Other than that, I cannot think.
Remove the fans from the HC, and see if they pick up flow. If not, then maybe they are runnung at 75cfm. If they do, well then, no problem.

They are definately not running at 75cfm because I have a 90mm 75cfm fan that i plugged in to compare and my 120mm are running at litterally 50% that. But then again it is a 90mm fan which could mean it just feels like more because it is comming from a smaller source.
