420 Rad /w 140mm Fans or 360 Rad /w 120mm Fans?

Can anyone recommend some of the best Static Pressure 140mm Fans for Radiator? I'm planning to use either a 420 Rad or 360 Rad. I know that the 420 Rad would have a larger cooling surface area which gives better performance over the 360 Rad, but then I heard 140mm Fans for 420 Rad are not very good with Static Pressure as compare to a 120mm Fans which has a higher Static Pressure. So which route should I go with? 420 Rad /w 140mm Fans or 360 Rad /w 120mm fans? Any info would be appreciated, thx.

Let's say both Radiators have the same thickness and fins, but one is 420 Rad and the other is 360 Rad.

Um thickness for Rad is around 45mm to 60mm max, and FPI between 8 fins and 20fins.

Let's just make it more simple, What are the best 140mm Static pressure fans on the market today? I know The NoiseBlocker PK-2 and PK-3 140mm fans are pretty good, but are there any better ones out there? thx.

The HIGHEST static pressure fans readily available are probably the San Ace 109P1412M101 @ 5.309mm/H2O, but sweet jebus, they will make you deaf. I personally like the performance/noise ratio of the Phanteks PH-F140MP, Noctua NF-A14 PWM, Noctua NF-A14 iPPC2000, and the unusual Thermaltake Riing 14's. The biggest driver for selection is noise when all things are equal. I personally use some of the Swiftech Helix 140 (non-PWM) on my 30FPI 420mm rad today and keep them at around 750-800rpm idle, 1000rpm load, but then, I'm not super sensitive to noise while gaming. (heatset is on) At 750rpm, I can't hear them at all through that rad and still get ok performance. My bottom 16FPI rad uses the Thermaltake Riing 14's as they push a lot more CFM with great static pressure to provide the primary airflow for my chassis itself.

I only do push/pull, so ultimate, world-ending static pressure isn't a huge concern. Noise and airflow are, with static pressure being important up to a point.

Well.....that narrows it down to "just about every rad on the market"......

First, all fans have static pressure, so all fans are "static pressure fans". Second, certain fans will work far better under certain conditions than others. There is no "best fan", there is "best fan for the application".

Until you have some idea of what you are looking to do in terms of rads, or what you are looking for as an end result, it is absolutely impossible to give you any input. What you are asking is as vague as asking "what is the best tire for something that uses tires". Is it a hand truck, computer cart or monster truck?

Ok I like low FPI Rad, like around 8fpi - 9fpi Rad like those HardwaveLab SR-2 Rad with 60mm thickness. So you can say I'm looking for 140mm fans that are good for Low RPM (like around 700rpm - 1300rpm).

Cool. If you can supply your own decoupling, the Vardar F2-140 (1600rpm max) and Akasa Apache S-Flow are both pretty good. If you need integrated decouplers, I'm a fan of the Phanteks PH-F140MP and Noctua NF-A14. I'm only really giving feedback on fans I've personally used, so I'll let some others chime in and provide other answers. I have a coworker that uses the NB PK-3's and he loves them, so take that for what it's worth. The Tt Riing 14's are great, but can get 'wooshy' really quick at ~950rpm or more, so that might clash with your desired rpm range.

So since you used the Phanteks and Noctua NF-A14 fan, these are good 140mm fans right? but still no where as good as a 120mm fan correct? so a 360m Rad would still give better performance?

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)

This is exactly what I was referring to when I stated the "best fan for the application". You are looking at using very low fpi rads with very low air restriction, but you are busying yourself with chasing after static pressure that you don't need for the application.

To answer your question directly - you would have to make ridiculously bad fan choices for the 360mm SR2 to ever outperform the 420mm SR2 at like noise levels.

This should help you out quite a bit. Concern yourself with the linear flow through radiator tests, as well as noise tests -

Actually 420 rad with 120mm fans will give the best performance just need to use adapters. 120mm fans give better performance than 140's on rads IMHO...

Thx, this is "exactly" the answer I was looking for

With a number of 140mm fans geared toward rad use having come to market over the last year, this really isn't the case any longer.

so what 140mm fans are they?

Still dont believe they are as good as the 120mm fans and a adapter..

The Phantek F140XPs or similar are the way to go. My next favourite are the 140mmm medium speed Yate Loons. The Yate Loons are significantly better built than the Yate Loon 120mms. Stay away from the Swiftech Helix 140s. Unlike the 120mm version the 140mm has zero static pressure. Out of all the 140mm fans I've tried they are by far the worst. I also use 120mm Gentle Typhoons w/ the Bgears adapters, but I do believe the Phantek F140XPs are a better choice now. Although the F140XPs have more motor noise and likely won't last near as long.

What about those new EK Vadar F-2 140 fans? And those NoiseBlockers 140 PK-2 and 140-PS?

Also, what about PHantek F140HP and F140MP? is the XP version newest?

I haven't used the Vardar's yet. The Noiseblockers are ok. Not great though. The GT AP-15 w/ adapters and the Phanteks will perform better.

I should have specified the PK-2 not the eLoop. I didn't even know their was a 140mm eLoop.

Realistically no one is going to notice a difference in performance between the top bunch of fans anyways. IMO I'd just try to find a fan that sounds best to your ears. Martin use to post vids on Youtube w/ sound clips. Not sure if the new reviewers out there do or not.
