I would like to know if an additional res will work with the pump/res combo of an Eisbaer. I have added a 120mm rad and replaced tubing with clear tubes and Eiswasser crystal red coolant. I am having issues with bleeding the air out of the system as it would be complicated to fill and purge out of case and then install. Just installing one component at a time is challenging with limited space. Also can not see the window on the pump/res at all unless I cut an ugly hole in my case, don't want to do that. A small reservoir where I could fill and bleed from would be great but don't know if it will work with existing res, will air get trapped at pump, added res or both ?
