Intel Core i5-3330 3 GHz Quad-core microprocessor, with original Intel cooling fan, Used.

The fan's original twist-lock mounts fell apart years ago, so I fashioned new ones with the included nylon screws, washers and nuts. It will mount very securely, and exactly to the motherboard in the original holes and do not require any modifications at all.

Pulled from my old gaming PC built circa 2013. Worked fine, no issues.

Ivy Bridge. LGA1155 socket.

Integrated Intel HD Graphics 2500.
