Just a fan or a heatsink as well?
What budget do you have?
How quiet?
Will you be overclocking?
No overclocking as I use the system for Photoshop and Premier.
This is a great cooler for the price, nice and quiet too - will happily run with your CPU.
If you want truly silent then you could go down the passive route with the Thermalright HR-02 - however that is much more expensive at ~£52.
I'm not quite sure what you mean here. Are you saying that overclocking the CPU will not aid performance in these applications or you simply don't need the extra speed?
