It is always helpful to search the manufacturer's website for such questions.

But as far as I can tell, the German premium manufacturer be quiet! has opted for the highest quality and maximum energy efficiency. This means that there is no need for any purely optical and technically completely useless frills, as a glowing cooler is about as useful as a third leg and only costs extra money, which you would be better off investing in higher-quality components.
Or asked the other way round:
What do you prefer: a CPU at 65°C or a CPU at 85°C but with a brightly coloured propeller?

Measured figures (ACPI) are usually more convincing than putting a dinner jacket on a goat.

If it absolutely has to be something because you think you can impress your mates with it, get yourself a water cooling system.
But then please get a real one and not one with only two propellers.
