Simple water cooling question using AIO

[SteinerW]

I recently bought all the parts seen in my profile system, I've revived most of the parts, but I haven't built it yet. The only question is if I'm using an EK Predator 360 AIO to cool the GPU and CPU, should I still use a reservoir in the system?

The EKWB 360 comes with an integrated reservoir, you're all good.

 

Can't hurt, but not required.

Thanks. I might get a small one for the looks then. I'll see when I put it together.

I would. Sometimes water evaporates or gets dirty, would help to be able to see when it does though probably isn't needed for your setup

How could it evaporate from a closed loop? Not saying your wrong, I'm a watercooling noob, but I'm genuinely curious how this is possible? Even if it evaporated into vapor surely it would have nowhere else to condense but inside the loop preventing any net-loss of water?

well evaporate isn't the word i should have used but in a sense it fits. yes you are correct about how it shouldn't but not all loops are perfectly air tight. you may have a tiny leak that isn't noticeableand doesn't drip and over time that would cause water to escape(evaporate) and also once you take apart a loop and add to it there would be air gaps inside the loop that will eventually make it to the res in which case having a visible res would help.

Makes sense, thanks for the explanation.
