Amount of water for rezervoir

post #1 of 77
Thread Starter 
Hello just finished the loop I've been waiting for and have this question regarding water level in reservoir.

When powered off rezervoir is almost full but as soon as I power loop on water level drops all the way down, should I add more coolant to even the water level? Please halp! not sure what to do

Warning: Spoiler! (Click to show)
This is whole setup powered off


Close up to the rezervoir so you can see amount of water


This is powered on and water level goes all the way down

You have to finish bleeding your system and that should fix it. You have a ton of air in your loop.

You can fill the res while the pump is running just be very careful thumb.gif.

Is your pump speed adjustable? You could try cycling the speed to get some of the trapped bubbles out.

After you top off the res and put the cap back on, try tilting the case in all directions that should help as well.

Ok thanks but the main problem is just with reservoir water levels... unless you mean it should always be the same level...

When on it is one level - when off its another level.

So i'm just not sure if I fill up to the top when pump running - won't it cause extra pressure and be bad for the loop? Because when loop is off water level is almost full.

The reason I filled it to that level originally because there is a small tube running to that level from top inside reservoir, sorry it's almost invisible in pictures.

Yes the res should always be at the same level whether it's on or not, maybe like a 1/4 inch difference tops. Your system is air locked. You have air bubbles that the water is pushing around but not enough to push them to the res and let them escape. Notice your upper tubing is empty when the system is off? That's the air that's trapped. When you turn on the pump it's probably pushing the air into the rad and then sitting there. The res level is a direct indication of air being pushed around the loop, just not enough to move it to the res and disperse. Hope that helps clear up what i am getting at wink.gif.

Thats normal as even a fully bled system will have water level drop as its turned on. This is due to the water pump.

Its good to fully fill up the loop. But if its fulled up and you know it might spill when you want to refill again, get a towel thumb.gif

I see in the picture its not even fulled up properly, so you'll need to run the pump at full speed and keep adding water biggrin.gif

Its going in from the top, and out form the bottom so it difrrent.

I know that if everything enters from the bottom and I fill from top, water will drop when pump starts.

Keep in mind that having air bubbles in your waterblock or radator will decreace performance, so it can be a bad Idea to not fully full up the loop
