The Heatsink/Fan combo is based on the processor socket used.
After a few search hits, I have seen E210882 on Intel based motherboards, that use two different processor sockets.
The Socket 478, and the LGA 775 processor socket.
The socket for the Socket 478 has the pin holes. The Processor has the pins. (478 of them)http://en.wikipedia.org/wiki/Socket_478
The socket for the LGA 775 processor socket has the pins. The Processor has the pin holes. (775 of them)http://en.wikipedia.org/wiki/LGA_775
Identify which processor socket you have, buy accordingly as to the Heatsink/Fan combo.

Remember to observe Anti-Static Precautions, Thoroughly clean the top of the Processor's case, and aplly fresh new thermal paste.
(A Processor is the most susceptible hardware component to Static shock)

If you would like advice on how to properly clean the processor's case, properly apply thermal paste, and/or what Anti-Static Precautions are, post in a Comment.
