Well, screwdriver did the trick, and yup, the anodizing has failed in two places, one about the size of a dime, the other only a third as big. The block has been eaten away maybe halfway through in these spots. Is there anything that can be done to save the block? Was planning to use Zerex super coolant(10%? more=better as far as anti-corrosion goes, right?)+distilled water, but am unsure whether this would be enough to basically STOP the corrosion, leaving the block functional, or if it would merely slow it, given that the alum. is no longer protected by the anodization.
Obviously I'd be better off getting my money back, but this doesn't seem too likely given that I bought these things at least 3 months ago now... Positive heat left and everything. I feel like a total fool for not taking the time to inspect them better. Plus, I sold my heatsinks already and don't even have the money to buy another set of those, let alone new waterblocks...
