POV-Ray is very FPU intensive, your other programms probably don't use 
the FPU as much.
If an application use the CPU at 100%, but is mostly doing logical 
tests, bit-wise operations, branchings and data moves, it will hardly 
make any heat.
A good example of something that can use the CPU at 100% and don't 
generate heat is the "idle process" that is only a small loop...

I don't know if you checked, but some dust on the heat sink can have a 
huge negative effect on the cooling. It acts as insulation and restrict 
air flow.
