Which makes less noise?

[helen_24]

I have the option between an i5 520m processor with an ATI FirePro 8720M graphics card and an i5 560m processor with a Nvidia Quadro FX 2800M.

Which would make less noise?

Is this a laptop we are talking about ?

I might be wrong but I thought CPUs don't make noise, only the fans on them did.
