How to collect air bubbles in liquid system...

[gulfcoastfella]

Hey,

I'm assembling my first computer, and while some basic principles of liquid cooling make sense to me, others are harder to understand. I accept that air will collect in the system over time, but one answer I don't know is: where will the air bubbles collect?

My 3x120 radiator is screwed to the top of my case where air is forced out the top. I would assume that most air bubbles would collect at the highest elevation in the system, which if I put my reservoir inside the case the highest elevation would be the radiator. If I put the reservoir outside the case and make it the highest elevation, does that mean most air bubbles will collect in the reservoir instead?

Or am I completely off regarding elevation's impact on air collection?

If you are using a T line, the air pockets will collect in it generally. If you are using a pump with a reservoir top, you can open the screw onto it the first few days while its running and let it bleed the air out, and once you put the top on you shouldn't introduce any air into the system. The small amount of air that will be in the rad will not adversely affect performance by that much. As long as you bleed as much air from the system as possible and keep it sealed...you'll be fine.

If you're having troubles with it bleeding tip it on its face(or back) that way the inlet/outlet is on the top. If that doesn't work, shake it.
