Water cooling - levels increase at night, overflowing the reservoir.
Water cooling - levels increase at night, overflowing the reservoir.
I have just set up the water cooling system and it is working properly.
The resistance value is the highest point in the case, connected to the radiator, then the pump, followed by the GPU, then the CPU, and back to the resistance.
After I confirmed that all trapped air was removed, I noticed something strange.
Every morning, the resistance has run high (because of small breather holes). There are air bubbles in the system, but there are no leaks otherwise.
So from the first impression, it seems like water has been added, which doesn’t make sense. How can there be air bubbles if there are no leaks?
I’m completely confused.

Yeah, it seems the air is still circulating, probably through the radiator. Interesting that there are breather holes in the reservoir...this could let water evaporate, which isn't ideal. It might also cause water to settle if the reservoir isn't at the top of the loop, helping balance the water levels.
depending on your loop arrangement and parts such as rads and pump, removing air might take several days (and occasionally weeks).
here are some points:
1. connect res directly to pump intake – the pump must never run without liquid.
2. once the loop is filled and all air is removed, i typically perform a stress test for around 30 minutes with fans off to increase coolant temperature, then seal the loop completely—no breathing allowed.
temperature changes in the environment can lead to expansion or contraction of the loop. because your loop isn’t sealed, liquid may be pushed out and the volume will be filled with air.

It might also cause water to settle because of gravity if the reservoir isn't at the top of the loop and doesn't help balance the water levels.
There isn't a straightforward method to link the pump-inlet directly to the reservoir. However, I prefer the concept of keeping the system well and warm, completely sealed. I'll attempt to connect the breatherholes, move the case extensively, increase the temperature, then add coolant and secure the reservoir tightly.
