Only if you trying to levitate your case off your desk ?

Im think you are gonna use these on a cooler but I'm not quite sure as yu references a rad fan article, so will try and cover all the bases
1. While higher SP fans were useful in the 90s for water cooling in the days of 30 fpi radiators, they simply not required with today's radiators which are typically 8 - 12 fpi and air coolers. Up thru 2010, we sometimes used 1500 and 1800 rpm fans but since then, we haven't used anyting other than 1200 rpm fans in all of our builds. You will rarely see an air cooler with greater than 1500 rpm fans. AIOs with aluminum rads will go as high as 2400 rpm to offset the poor heat transfer of the aluminum ... but frankly I'd want 30 foot KB, mouse and monitor cables as I'd have to put the box in the next room.
2. Lets look here:

The NH-D15 manages to keep the CPU @ 70C @ 33 dbA with its 1500 rpm fans
The Cordair H100i only manages to keep the CPU @ 73C @ 68dbA with its 2700 rpm fans
The AIO w/ High SP fans leaves you with a system that is
11.3 times as loud all for the benefit of a CPU that runs 2C hotter.
3. Be aware that published fan specs are "phoney baloney"
This is just a quick graphing demonstration of why fan box specs using static pressure and max air flow are generally poor tools in comparing fan performance. Very much like pumps, fans have a pre…

Here we see that the specs are:
Cougar Vortex PWM
Max Airflow = 70.5CFM
Static Pressure = 2.2 mm H20 (0.087 H2O)
And the reality is .... the fan delivered 33 cfm @ 0.04 in H2O
IOW, 47% of its claimed flow and 46% of its claimed SP
Gentle Typhoon AP-15
Max Airflow = 58CFM
Static Pressure = .08inwg = 2.03mm H20
And the reality is .... the fan delivered 38 cfm @ 0.047 in H2O
IOW, 66% of its claimed flow and 59% of its claimed SP
4. What are these fans for ? Are we talking heat sinks or case fans ?
5. Here's some "let's see what happens when we swap fans articles"

Take the 1500 rpm NF-A15 fans off a Noctua cooler and replace with 1200 rpm Phanteks and , at the same rpm, temps drop 6.3 C. Even with an extra 300 cfm, at 1500 rpm, the Noctuas leave the CPU 3C hotter

Scroll all the way, way, way down to see the temperature / noise rankings ... and read the conclusion. At this point in time (2013) fan design had reached a point where one no longer has to sacrifice performance for low noise. Today's coolers, rads and even case designs are optimized for lower (1200 rpm) to medium (1500 rpm) speed fans. We last used medium speed fans on SLI / CF builds, mounted on the back of HD cages to blow air between GFX cards ... haven't done any of those tho in last 5 years.
"In our last 120 mm fan roundup we lamented the fact that many of the best sounding fans faltered in our thermal test, posing our readership with a vexing question: Which is more important, acoustics or cooling performance? For this first batch of 140 mm fans, there is no such dilemma. The Phanteks PH-F140HP/TS is the clear winner in every respect. It edged out the new Noctuas every step of the way, delivering the best overall results of any fan we’ve tested thus far. To top it off, it had cleanest, smoothest sound of all the new fans in this roundup. If we had to start from scratch, this might be our new reference model."
I'm not saying higher rpm, which brings both more cfm and more SP won't make things cooler.... I'm saying that reducing temperatures beyond a certain point doesn't bring anything to the table. In the comparison referenced in Item 2, going from 1500 rpm to 2400 rpm not only lost 2C but delivered more than 11 times the noise. And lets say id dropped ya 2 or 3C ... what does 68 or 67 do for ya that 70C wasn't ? We have an ancient SLI build here.... and if I run the fans at max speed, my GPU temps are 39C under Furmark and the system is quiet but audible, If I let the fan curve control fan speeds (50% speed at 75C on CPU), GPU temps rise to 44C under Furmark. So it's 39C and the noise is not annoying or 44C and you can't rtell that the system is on as fan speeds only get up to around 625 rpm (Furmark) ... in gaming, hey significantly slower.
All that being said, you may have no other option if say using a small ITX case with inadequate air flow or a poor case design that doesn't allow for adequate cooling ... A $50 air cooler like the Scyther Fume 2 with 1200 rpm fans outperforms almost every 2 x 120mm AIO. The $150 Corsair 115i Platinum w/ 2000 rpm fans edges the $50 cooler by 2C but at the cost of being twice as loud. I just don't see that kinda trade off being worth it.
I looked at the review linked above and I would agree with some of the the autor said .... if this was say 1995 or 2002 even ... If you have a radiator with a high FPI then you will want high SP fans... but since those are pretty much extinct, I don't see how it applies today.
On a cooler... there's a reason Noctua uses 1500 rpm fans.... they chose NOT to use the 2000 rpm ones.
Now we get to the nitty gritty.....The 2000 rpm fans you looked at cost $60. For the same $60, you could buy a new Scythe Fuma 2 cooler which will outperform most 2 x 120mm AIOs, beat the Noctua NH-D15 in AIDA 64 temps and by 3 dbA in sound (for just 2/3 the NH-D156's price) ... and it's not too tall either... about 154mm IIRC.. your current cooler is about 141 mm ... and it can mount a 3rd fan ....better cooler, better fans, better temps, better sound at no extra cost.
