Strange Rad noise

post #1 of 10
Thread Starter 
I fired up my loop last night and let it run for 3hrs straight for leak test and it passed with no problems BUT.... i dont know what it is, my 120 rad sounds like water is being poured into it. i dont know if its air that just will not get out. Its really hard to explain but all of sudden the pump sounds like it did when i first started it with tons of air being pushed through. Also when the pump is silent with no air going through it.... the rad still sounds like its pouring water into it.... i have a koolance flow meter and the flow is great with 5000rpm according to it. anyone have any suggestion as what it could or what i can try to making is completely silent? image attached of the loop with the 120 rad on the left.

It just needs more time to settle a bit. Give it a couple of day and you can rock the case side to side gently, that should help dislodge the bubbles. But generally takes a few days, as did mine.

mine does the same thing when i drain it and refill it. its just air in the rads and it'll work itself out. it takes mine about 1-2 weeks to get all the air out. watch the level in your res and over the next week or 2 it'll slowly go down as the air gets replaced with the water. you can try tilting the case around to get the air out but that only helps so much. so just give it some time.

No, the cap can stay. Your not adding more to the Res, the water is being replaced. No need to open it. You can't cause a magical addition of mass inside the loop...
