Hi Chris thanks for the information. That is ruled out then.
I have seen that i have one memory waterblock upside down. I can not folow the exact route inside the memory coolblock so i wil change it.
For the rest i have to look what els can be that couses this problem problem.
Like i mention befor it start with 1,9 liter p\m and within seconds the flow almost ends to 0,4 g\pm for two pomp on two radiators.
The flow start at the res, pomp , pomp, radiators, motherboard and then back to the res. between the pomps and the quick disconnect the tubing is hard as if it cant go tru. Mayby the valve of the outgoing from the pedestel closes because the flow pushing upward.
I am glad you mention that thanks
