Water Cooling Help

[enricong]

I recently connected up my first watercooling system. Actually, I just connected the parts, I have not yet installed it in my case yet.
I have had some problems because I found out that I ordered the wrong radiator and got 3/8in instead of 1/2in connection.

Anyways, I was eagar to try things out so I was able to hook up everything. I figure I'll use it til my replacement part arrives.
The system should still work with some bubbles, right? just not as efficiently?

BUT, I have noticed some "issues". I can not seem to get rid of the air bubbles. I think this is because of my radiator's smaller connection. I think its slowing down the flow at the output. I have a bleed valve thing and it does help to remove most bubbles.
When I get my replacement part and convert to all 1/2in connection, should this fix my problem?

How should I mount my radiator? should I have the connection at the top or the bottom? does it matter?

Also, I left this setup running overnight to test for leaks.
I noticed that after a while, it is hard to tell if there is any flow at all.
I have to shake the radiator alittle, then I see some air bubbles fly through the tubing.
I'm hoping that this means that there still is flow but I just can't see it because there are no bubbles in the tubing

If you don't have a reservior it will take several days of running, or about an hour of flipping the parts in every direction to get the air bled. If you have a reservior, just let it run a little while. If you're shaking parts, and seing bubbles, that means there are trapped air-pockets inside.
A radiator is already the biggest flow restriction, and smaller fitting than the rest of the system just makes it worse. I have the connections in min at the side. It shouldn't really matter since the water is being pushed through it.

Hey enricong;

I see you decided to try your luck here and at overclockers. I was one one the people who responded to your thread over there. So, are you going to get a res before it's too late?
