First watercooled build, need advice.

archangel543 · November 30, 2021

Hello,

i built my first watercooling system and have some questions.

1. the system makes bubbling noises. as i understand there still is air in the loop, how to get them out without having to shake or tilt the case?(corsair 1000 with 2X480 and 2X360 rads, very heavy)

2.the loop creates a vacuum, is this normal? every time i open the fill port the loop sucks in air.

3.is it best to have a fan curve for the pump or have it set to a fixed speed?

Thx in advance!

1.) You can vary the pump speed, but shaking and tilting the case is the best way to get it out.

2.) As far as I'm aware, no. Are you opening the fill port when the system is still running?

3.) Either one is fine. My system has a fan curve for the pump, since I water cooled my system for silence, and thus having the pump run slower when it can means it has lower noise output.

Yes, i am opening the fill port when the system is running

OK, that might be what's causing it. See if it still creates a vacuum when the system is off.

1) Unless u have a vacuum pump to pull the air to the res ull have to shift the system around to get the air out.

2) Yes this is normal, a slight pressure changes will occur as water temps change. This will be more pronounced whilst u still have air pockets shifting around the loop. When bleeding air from other areas of the loop, once the air gets into the res, open the top of the res to bleed the air, then repeat.

3) Higher the pump speed the better. Run it as high as u can handle noise wise. I for example run my D5 vario pump on its highest setting (5) and have done for ~7 years.
