If you have a power supply with dual fans like the case that's way down below in the link above, does that significantly help make the computer cooler?

It would certainly help keep your PSU cooler.

Yes, typically a dual-fan PSU (one sucking air into the PSU from inside the case, the other blowing air out the back) will perform better than a single-fan one in terms of airflow and thus cooling. You pay for that in the form of extra noise.
