Hi all, could someone tell me if I can use EKWB EK-RES X3 - Multiport TOP as a inlet and just use the outlet on the EK-XRES 140 Revo D5. In the manual it says "Don't use top port as inlet only for fill" on original top which only as 1 port.
At the moment I have my system tubing going into one of the top ports and the outlet going into the bottom 240 RAD>GPU>N/B> 360 RAD>CPU>RES, but as I am trying to fill it (when I turn the pump off the water is flowing back to the res) this can't be normal
Any help would be good.
Thanks
