Somehow I don't think Intel know more than people who are actually using it.
Uh, I tend to trust people who are engineers, have degrees, do data center design, understand what case -vs- ambient temperature coefficients mean, etc. That's my world. Not seen a water cooler in a production server or workstation I've ever worked on.
Chip makers understand more about thermal management and the thermal efficacy of their products more than people who put LED fans in cases, talk about over clocking and 'skateboard' in the same sentence, etc.
Hence, need for CPU lapping on some CPUs, Devil's Canyon with better internal thermal grease etc...

Interface materials are some of the biggest ripoffs in the industry and have been consistently debunked by engineer after engineer. Again, I rarely see these materials in production class computers and servers, and hence don't take it seriously. At best lithium grease. The best thermal interface is otherwise a non interface. Adding a few milligrams of flake silver to grease doesn't make it a better thermal conductor either.
The article (if English is your primary language) doesn't conclude anything about the necessity about water coolers. They are just 'there'.
This whole paragraph does not make sense. How is it a possible issue and not a solution? Unless you are talking about internal water cooler like the one in the link above.
What are you, my senile English teacher? The biggest producers of heat in a computer are those systems that use the most current. Once again, basic physics. Add on enthusiast GPUs consume orders of magnitude more power than CPUs and therefore produce far more heat. If you aren't using one of these GPU's then thermal issues are likely not a problem.
Conventional CPU's at stock settings are designed to work with the fan that's shipped with them.
Another solution would be to install another fan or two on the case. One on the side and one on the top. They don't have to be fast loud fans. I have very slow quite fans but designed to move a lot of air. So even though I have 6 fans running my system is barely audible.
Again, production / stock computers don't typically need augmented air flow because the engineers who design them use pretty good models to keep them cool. It's when you start adding multi hundred watt GPU's that multiply the thermal factor by an order of 5x that problems start.
So, it's really GPUs that have crappy thermal management causing most of the issues.
Depends. Some video card designs have secondary cover with fans that throw heat out of the case and since there is no heat coming from CPU with water cooler installed, inside the case is very cool.
Very few GPUs do this, and again, not everybody needs a 300watt GPU in their computer along with LED fans, over clocking, a plastic side panel, and parents yelling upstairs about taking the garbage out.
