Hi.
That's the one from your ex system, yes. I don't need it as I already have an extra CSPPC in my A4000. I did a splendid job on reconditioning it though (cleaning, etc.). You had a very noisy fan over the PPC chip which seemed to be on its last legs, plus the heatsink grease between the heatsink and PPC chip definitely needed change as it dried off during the years.
