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?

When you turn on the pump, most of the air bubbles will bleed to the reservoir. Even though the radiator will be the highest point, eventually most, if not all bubbles will make it to the reservoir. Sometimes a little tapping or tipping the entire case and help the bleeding process.
