Why is the Xflow rad not filling or holding air?

post #1 of 4
Thread Starter 
I guess I should have done more research but I have found bad things out after buying this radiator (bout these Xflow rads)

....

So I changed up my loop, added a GTZ block and a 120mm Rad in the rear (see pix)

The loop has been running for 48+ hours now and getting great temps, blows away that hold H50 i had, temps are still holding strong @ 40c idle

Anyways when I turn it off, the water flows back from the top inlet of the radiator ??? WHY????
Air in the radiator?
Way the loop is setup?
Not enough pump?

Res/Pump > 3x120 rad > GTZ block > 120mm rad > GPUs > Res







Thanks

If it flows back (and that is your rad on the back exhaust port) and there is an air bubble, it's air. Take the rad off and twist/tilt it around till all the bubbles are worked out.

I have a 360 Xflow mounted on the top of my Haf X. I have seen this problem at all. There may be a air pocket in the rad possibly. How full is your res?

Maybe I could try standing the case on the end where the rad is mounted? not sure if there is enough tubing to remove the rad at all.

Ya I am thinking there is air in the rad, I figured it would go away but it has been over 48 hours and still when I turn it off this happens.

Nyghtryder_9, you have seen this problem or you have NOT seen this??? I was thinking about getting a Xflow xtreme for the top but now I am not sure

Res is full, XSPC 750 res/pump btw and I would say it is about 1cm or less to max
