I'm assembling a system with an LGA1155 CPU. Just before applying the thermal paste I cleaned the base of the cooler and noticed what appears to be corrosion on it. It looks like the base is copper-plated, not solid copper, and the plating is missing in some spots.
How important is this? Should I toss the cooler, or consider it a non-problem because thermal paste will fill any gaps?
This is a used Intel cooler which came with a used board. Probably it was new when the board was new, and was left loose with the board when the CPU was removed before the board was sold.
