Noob, if you use well water, dont do direct heat exchanging. You will fuck up your waterblock and contaminate the water vein.
Do it right and do non direct heat exchanging. You can keep your waterblook alot longer with proper coolant too.
Run three consecutive months, No problem, As long as no copper, Only plastic and aluminum, is ok
