Liquid cooling Q's

[knowledgegranted]

Well since I am to make a home-made liquid cooling system soon, I obviously have some questions that need to be answered about liquid cooling systems; help me out if ya can please. :rolleyes:

1. Does the fan on the radiator 'push' or 'pull' air from the radiator?

2. Will you benefit from a fan that has a higher CFM on the radiator?

3. Does a pump 'push' or 'pull' the liquid through the loop?

I will probably have more as I go through the building process, also does anyone know a good online copper retailer?

Thanks in advance!

1. either way will work as long as there is adequate airflow as far as I know

2. To a degree, I would say yes. The more airflow volume/velocity that crosses the fins of the radiator should theoretically equate to better heat transfer.

3. a pump displaces water on one side and places it on the other, so the answer to the question is sort of yes to both. But for practical purposes, the pump should be located at the lowest point possible in the system and the res should be at the highest.

hope that is accurate and helpful.

Helpful definitely, for accuracy I would not be the one to have the ability to say so.

You do want a fairly decent CFM on the fan, however part
of the reason to have water-cooling is that it tends to be quieter
along with the benefit of better cooling.
One of the loops on my previous system has the dual radiator
on the top of the computer case. So i really wanted a couple of quiet
fans up there.
The SilenX fans are great.. Nice and quiet and good CFM's for the
DbA rating. I just picked up a few the other day in fact. 74 CFM's, 14DbA.

$17.99 each. We have a local Microcenter here and they are
$29.99.. Ouch.

Hope that helps

I might be able to help you out a bit more.

1. you can usually put a fan on both sides of the radiator. One pulls and the other pushes. It does not give you twice the air flow however. but it give you more airflow for the same fan speed. (hence, less noise)

2. Higher CFM fans do not more any more air volume than a lower one at one point in time. They just move it faster and thus, Louder!

3. Pumps usually are best to push water through the loop. jdbnsn is correct that you want the pump the lowest and the resevoir the heighest. so that any air trapped in the system eventually makes its way to the top of the resevoir. your pump should pull fluid directly out of the resevoir. Gravity helps this process if the pump is the lowest in the system and will give you a greater pressure on the positive side of the pump.

as for the copper retailier, are you referring to blocks of copper? Have you done a google?

1. it can push or pull, it depends on how you mount the fans. i prefer both and have double fans. i have 12 high speed yates on 2 MCR320's (triple rads)

2. it depends on the rads. for rads with high FPI (fins per inch) such as the black ice GTX you need higher pressure and higher cfm fans for best results. for rads like thermochill, feser, or XSPC RX series low speeds work great.

3. it does both. it pulls from one side and push from the other.

as for the location of parts it makes no difference outside of longer times to bleed. for loop order the only thing that matters is that the res or t'line goes before the pump so the pump will always have water. never run a pump dry!

being that i run t lines in both my loops the air will bleed over time if you place the T properly. it takes longer but it will bleed.

Ok, thanks everyone! Great help in the WC process.
