Will those fans fit? Which one is better?

Would those 120mm fans fit above the cpu cooler? if yes, should I have 2? and which one is better? and why?
Case: carbide 500r
cooler on cpu: noctua NH D15
fan(2) for the top of the case: Noctua NF-F12 PWM 120mm Case Fan 1500RPM or Noctua NF-P12 PWM 120mm Case Fan 1300RPM. For some reason, the 1300RPM one costs a fraction more than the 1500RPM one.

The 1300 RPM fan will provide sufficient airflow and be quieter. The 1500RPM model moves 93.4 cubic meters of air each hour and makes 22.4 dB of audible sound, while the 1300RPM model moves 92.3 cubic meters of air each hour (almost no difference) and produces 19.8 dB of audible sound (that's a pretty good difference). The 1300RPM model costs more because it has a more intricate blade design, which makes it more difficult to manufacture, which raises the price, and so on.

And the Corsair Carbide 500r is specifically designed to have all fan mounts occupied while CPU and GPU coolers are also installed, you should have no clearance issues.

Thanks. One last question: with the two fans (a couple of the 1300RPM model) mounted in the top, above the Noctua NH-D15, I'm just wondering if it actually benefits to have two fans above the Noctua NH-D15? because of the architecture of the Noctua NH-D15, I wonder if air flow from the top will actually help or might actually make the Noctua NH-D15 less effective of a CPU cooler. Might be a silly question...

As long as you're using them as exhaust, you will have no problems related to airflow.

Here's the thing, having an exhaust right next to a heatsink helps for the heat from the CPU to escape rather than just mixing in with all the different temperatures of air throughout the chassis
