use of a corrosion inhibitor with alu is always recommended
so you recommended a solution not relevant to the problem ?
"I never claimed that galvanic corrosion was a real problem in water cooling. I have simply pointed out that if there is no metallic path between the waterblock and rad there will be no corrosion cell between the two."
ok, you win

Bahhhhhh,
No DI/DW will not stop corrosion, but it will help to minimize it. High resistivity electrolyte will slow the e-chem process.
Second, Galvanic or disimiler metal corrosion (al rad and CU block) may be a problem within some peoples WC systems. In most cases there won't be a metallic path so their will be no need for concern.
Third, if a specific component is found to have problems there are a number of solutions. For example. A piece of thin zinc ribbon submerged in part of the WC loop (say the res or T line) then connected to the object that is to be protected (the Al rad) would likely provide enough Cathodic Protection to reduce the corrosion rate to a crawl. As many people know this is often done on boats. It is also used for protecting burried pipelines, underground storage tanks, sheet pile walls, H piles, and industrial water cooling applications.
