Front Radiator Orientation

[Nick980]

Hi all,

 

Rebuilt my exolv x system earlier this year, has two 360mm radiators in it, one in the front and one in the top with the front acting as intake. Couple of times as week I'll hear a loud gurgling noise and several large bubbles will come out of the front radiator and go into the res. The ports on the radiator are at the top as I thought this would be better getting air out of the loop but the fact that after several months of running for 12+ hours a day I'm concerned something is wrong.

 

I cannot find any leaks or evidence of leaks in the system and the computer itself runs normally, am I correct it having the ports at the top or have I made a mistake? Debating dropping the front 360 rad and replacing it with 3 140mm intake fans. Loop only cools a 3800xt and vega 64 so not sure two rads is worth it.

I think the manual for my Corsair H55 recommended having the ports at the bottom, but I forget.

 

If someone knows better, please correct me

did you do the watercooled dance when you first filled up the loop?

Meaning when you first fill the loop you need to angle the case to like 45 degrees on all axis and shake it a little. this gets like most of the air out of the system. sometimes a little is still in there but not much. so if you didn't do that then that's all you're seeing is trapped air.

I have a 360 on the front of my case ports on top and a 240 on the top ports forward, it took a lot of shaking on the first fill but i'm pretty sure there is no air trapped inside the loop anywhere.

Its probably fine, indeed ports up with make bleeding air easier, wheras ports down make draining easier. As for the air appearing, I'm going to guess its just small bubbles appearing through evaporation/degassing, accumulating in the radiator, and then gurgling out when enough has accumulated. Unless you are observing constant and noticeable volume loss in the reservoir, I doubt it is a leak, and so no need to worry.

Yeah did the dance, done it several times since as well
