I read many posts about cooling systems but not enough about the actual coolant that goes in them. I have the old Corsair Nautilus 500 external cooling system for my cpu and recently the pump got clogged, which was an easy fix. But i think the coolant created residue inside it.
I am looking for a good coolant and read some bad reviews about the popular Thermaltake one, which should be used only in Thermaltake systems. And read some good reviews about the Feser One Non Conductive Cooling Fluid - 1000 ml - UV Blue which is not so popular.
Any ideas of what coolant I should get to keep my water pump alive just a bit longer ? My cpu usually idle at 40c
