You might as well go all the way now you have bought one package of c1.
The most important part to cool is the lower 4 clusters as they feed the CPU.
The upper single cluster is for the memory controller and it should not heat up as much as the ones feeding the CPU core.
All four clusters for the CPU are stressed evenly, ignoring component variation, they will all need the same degree of cooling.
If you only mount heatsinks on one cluster, the remaining 3 cluster will still overheat.
