Are you overclocking?  If not, you should not need a better heat
sink/fan, you probably have a bad physical mating of the heatsink to the
CPU.  Almost all processors come with a sufficient fan/heatsink for cooling.

I might be overclocking. I have a DFI nF3 250Gb MoBo running at 2.4 GHz, 
which the documentation says is supposed to support overclocking, but I 
don't know how to tell if it is overclocking, or manage it, or turn 
overclocking off.
