A clear example is Noctua, one of the world's most famous and tallest manufacturers of PC cooling. The Austrians have been exposed to their barbarian heatsinks and black followers and beiges, but have recently introduced a new range of black heatsinks that is, improve thermal performance Why is this so if it's just one color?
It's not paint, it's a drag process
The secret is that the matte black color of these heatsinks doesn't really paint. Manufacturers often cover aluminum strips of heatsinks with a thin layer (referring to microns) of anodised aluminum oxide by an electrochemical process that forms a thin porous layer it protects against being worn
Now what they have done is to incorporate carbon particles into this anodizing process, filling the pores, because they take advantage thermodynamic property of black color. This property is based on the measurement process, which states that the absorption capacity (anything, light, heat, etc.) of an object is proportional to its removal power. In this case, the darker color is better the ability to absorb and release heat that is the typical silver color of aluminum, and that's why it develops (slowly, don't go away and believes it will improve many degrees) of heat.
In addition, this creates a product that wears a more fun uniform, and is actually more impressive and fun to watch than a heatsink with standard aluminum sheets.
How much performance is achieved with a black heatsink?
A little bit, certainly. According to tests conducted by ABL Heatsinks, the net gain is around 30%, which is a total figure that looks great, but is actually a 30% improvement in terms of input and output power.
This translates into the fact that performance gains in fact do not reach their full potential, and at least can reach half the Celsius minimum. At high heatsinks, all the tithing wins, of course, and if at the same time we find weaknesses, resistance and longevity, then why not do it?
Reasons why black heatsinks are better
We've talked about them all but we'll summarize them. Black heatsinks are better because they provide slightly better performancebut also because they resist the passing of time better because of that layer of anti corrosion they have, they are low drivers electric, something that really interests us within the PC, and it also has a lot of good and more beautiful (You know that black blends well with everything, right?).
If all is service, and there is no difficulty, why not all heatsinks are black? Yes, because there are no user interfaces but manufacturer, since this means introducing one more process during manufacture, and the subsequent cost of materials and time. Also, not everyone likes blacks.
