Tubes on top

[Sat1600]

I'm doing some work for a friend.  He has a PC that is the main workhorse. (Buissness no gaming) The PC has an I9 14900k with an EK Nucleus AIO CR360.

 

I noticed that the tubes at the top of the block. Is it worth messing with? The Radiator is at the top.

It does not matter. 
This is the annoying downside of gamersnexus looking for any kind of thing to talk about, people being concerned over nothing. Pretty much as long as you don’t have a radiator mounted to the bottom of your case, it’s fine. And even if you did, it’s probably still fine.

Thanks. I thought as much

It does matter, though. If the tubes don't go through the top or, depending on where they are on the block's side, through the side, you're going to have air build up in the block. At best, this will eventually result in gurgling and increased heat. At worst, your pump can die.

I would leave the rad but flip the pump 180.

keep in mind that when trying to get the air out, alot air goes out of the "pump"house when the unit is turned off

 

tubes down: not so much

I have mine off to the side, but it was designed to run like that.

   It def matters cause when they fill these at the factory they must leave a air gap in them for expansion and pressure from heat. Air naturally is going to want to rise and go to the highest point, which is why you want the rad to be the highest point cause it has tanks on either end that can accommodate the air bubble and keep it there.

    In the scenario in the picture above it should be ok like that though i agree that the cpu block tubes should be to the bottom instead, preferably and if possible. You def want to utilize natural falling gravity where ever possible to help the pump push the fluid around. That will help it live a longer, better spent life.

The force of gravity will be overwhelmed by the pump almost as easily as fans overwhelm air convection current. Suggesting that the tubes come out of the bottom of the block ignores the fact that air can then be trapped inside, although how readily will depend on the pump speed and flow rate.
