could i not also just replace the cpu use the sealed box method as i didnt damage seal keep the fresh cpu fan in there return for idk better price elsewhere and if they do ask after a while returning asking for the correct item i can deny and say this is what i had recieved and then seeing the fresh cpu fan compared to my dirty one would help support it along with the untampered seal?

Amazon checks/opens sealed box returns.

When they do, they'd know that It's Impossible for the manufacturer to pack an old CPU. As such, Amazon will be firm with their request to return the correct one. Moreover, It's their policy to dispose of Incorrect returns, so say goodbye to your CPU.
