So I moved some parts and put return from cpu to bottom side of res for better bleeding.
I have big problems, first there I can barely fill the res over the top of res as funnel has huge leak, so this is not a problem when pump is running,
however when pump is turn off the water push to funnel leak and all over PSU and little bit on GPU.
sometimes when pump is running air gets inside reservoire and the water goes to funnel even when pump is running, only solution is to tilt case and let water fall to floor otherwise PSU and computer get totaly wet.
So now I have sealed top of reservoir and remove tube + funnel, but now air not get out?!
So I need to keep the funnel and tube and let the pump run, however there is guarantee to be alot of leak and papertowel to use.
Also I have big problem, if I turn pump off then the water push out over PSU as there is bad leak on funnel, so then there is so much air that the water gets pushed to funnel and then power supplie get alot of water on it and the fan is on top so it is not good
I now have sealed where tube and funnel was, but judging from my understanding does not work as air can't get out?
Also I have made slightly adjustment to my system as of below picture:
edit--> so even if top tube has no water during bleeding it gets full of water and start leaking over PSU when air goes to res I assume.
