do you really want a technically assumption?
Ok..
1. The Heat sink you listed is a alu fin with a copper core heat sink.
Its design was very common on LGA775 Quadcore cpu heat sink.
LGA775 Quadcore Heat sink:
TS15A Heat sink:
What is the difference?
From the looks of it the height of the copper core.
Also the density of the alu fins which is wraped around the alu core.
Now Copper is a better thermal conductor then alu.
This is physics, so its undisputable, however many vendors have marveled on the idea to hybrid the heat sink copper / alu for weight and cost reason.
Copper is really expensive per gram vs alu, and also a lot heavier.
Now lets look at the heat sink evolution.
We used to have a lot heat sinks like the intel which used hybrid copper / alu.
A good example would be the zalman 7000 series.
what did we learn from it?
It sucked... that's why no one really got it over the full copper version from zalman.
So how did heat sinks evolve?
Heat pipes... thermal bridges which carried heat from source A to Source B using a evap process similar to what air conditioners use.
These heat pipe coolers now currently dominate the heat sink world due to how much more efficient they are in the ability to move heat from A to B much quicker and then dissipate it.
So now lets look at the cost of the TS15A
Newegg has it for 30.44 for this heat sink.

The other i recommended which is a heat pipe heat sink
Hyper Evo 212 is 29.99

So do i think intel knows what they are doing?
Of course they know what they are doing, but
they dont like what we are doing its that simple.
Also intel has no interest in the heat sink market, outside stock configurations, and if your looking at stock config, i dont see any real benifit over you getting a TS15A when a perfectly working and functional stock cooler comes with the cpu.
So if your looking at getting a cooler replacement, get a hyper 212evo, unless its too tall to fit inside your case.
if thats the case, there are much better sinks then even the hyper 212 which are low profile, but cost a bit more like a noctuna or a thermalright.
im sorry but i used to be a sponsored tester for cpu water blocks, and heat sinks.
And to me that article shows no form for credibility because he lacks to mention a lot of things for a test like that to be credible.
But without going into major details on how flawed his test bed can be, i'll just end it at that.
