Spirica Extended heatsink with fan for Radeon 9000 supports Radeon 9000 Pro 64MB/128MB Mac Edition. You cannot install the Radeon 9000 in the Cube because the card is too wide and interferes with the VRM. You need to relocate the VRM, which is possible with a PowerCube, for example.

This kit includes a two-layer heatsink with fan and four screws.

This heatsink includes a fan for better cooling.

Put the thermal sheet over the original heatsink. Then just attach the extended heatsink on the original heatsink, using the four screws.

Fan connector can go to J2 connector near the memory slot.
