The Blue Fan is 12v. The Original CSPPC Fan uses 5v so you will have to power this Heatsink/Fan Combo from a Molex plug using a convertor to mate with the Blue Fan's 3 Pin Mobo Header.
Also, the original PPC Heatsink is cut specifically to take the 2 x Metal Clips to hold in place with the PPC Chip, so @ best, you will only be able to screw the Blue Fan to the Original PPC Heat Sink unless you machine (Mill) the blue Heat sink to fit!
