Radiator mount in the bottom of the case

Go to solution Solved by Oshino Shinobu,

The idea is to not have the pump be the highest point in the system, rather than specifically not being above the radiator.

 

In the case of custom water cooling, you typically have a seperate reservoir, so as long as that is above the pump, you'll be fine.

Hello

i have a question 
The right way to mount the aio radiator
Is to keep the pump in a pisition below the rad so the air bubles dont stuck in the pump 
But the question is 
In custom water cooling 
Is the same idea is a must??
What if i place the rad in the bottom of the case ?
Would that be a problem
Cause i think the difference is here the pump is below the reservoir and i think there will not be a problem 
Or am i missing something?????

Yes i guessed so

But is there a chance that air accumulate

In the   cpu block since now its the highest

Point of the loop?

Would that be a problem

An interfere with cpu cooling???

Not if you bleed the system properly to get rid of air bubbles/pockets.

This is more of a problem with permanently sealed cooling items such as AIO. Because any air bubbles in one of those can't get out. Like you correctly said in your OP.

 

For a custom loop you bleed the system while filling the loop and for some time after. Since you can leave the reservoir or a bleed port open, any excess air trapped will eventually make it's way out. Running the pump at full tilt for a while helps as well, just make sure the reservoir is not so full that you cause a flash flood. I underestimated the pump strength in a loop I built not long ago, and evacuated some coolant from the reservoir by mistake while bleeding the loop. 😉

 

There are good tutorials out there for bleeding a custom loop. Well worth taking a look at one.

No.  Air bubbles are more of a cosmetic thing than an actual "problem".  

 

The only exception is if you have a very large loop and a pump that isn't powerful enough, you may end up with not enough flow for large air pockets to get cleared.   Or if you have like an upside down radiator (fittings at the bottom), there's probably always going to be air in it no matter what.

Thats what i intend 

I will fit my radiator in the bottom of the case

And am just wondering if the bubbles that will accumulate in the cpu block would interfere with the cpu cooling or not????
