140mm fans, all things equal, move more air with less noise. The advantage of 120mm fans, very generally speaking, is that they tend to have better static pressure vs. their 140mm counterparts with a smaller 'dead spot' at the fan hub. Now, from the radiator side of things, a 360mm rad has just under 75% of the surface area of a 420mm, so in order to show some kind of disadvantage, the 140mm 'dead spot' would have to impact ~25% of the radiator surface. Which it doesn't. Ever. So even making broad generalizations, I can't see how a 360 could possibly outperform a 420mm, all things equal. I always go for the maximum surface area when choosing radiators. Always.
There are still more factors to consider though, which is why I was asking earlier about your specific goals. If we are only talking about performance, the answer is to get a 1080 rad and San Ace fans, but we're humans that actually enjoy simple comforts and have budgetary requirements.
Considerations:
-Space: Does a 120 or 140-based rad make the most sense from an installation perspective?
-Availability: 120-based products are vastly more popular and widespread, does your ideal product exist at a price that makes sense? (Gentle Typhoons, for example, don't exist in 140mm format)
-Price: Because of the aforementioned, 140-based products are generally at a premium. Fans are probably the worst offender, often incurring a 30-50% markup over their 120mm counterparts
-Noise: 140mm fans with low to mid density 140-based rads will offer similar heat dissipation at lower noise levels, but cost more and take up more space (this one is tricky to state equivocally as there are some fantastic 120mm products out there as there is simply a wider selection of excellent niche products)
-Need: Do you need an extra 25% cooling surface? (in the case of the 360 vs. 420)
I'm sure there are more, but those were the ones I could sit down and explain. If you just do the basic math you'll find that 140-based rads have more potential capacity vs. their 120-based counterparts, but stating that one is better is back to the 'which tire is best for my thing that uses tires' argument. It depends a LOT on your specific needs.
To your first question, yes, the PH-F140MP and NF-A14 are quite excellent. (the Noctua definitely being better overall, but at a 20% or more cost penalty)
