I love the beige and brown. I think it is because of what it stands for: it shows the stubbornness, the will to not give in to fashion. It shows that the looks of the fan are not what you bought the fan for: the great engineering and vastly better performance makes the NF-A12x25 a fan that does not need to care about looks.
And because of that, I actually like the looks. I know I’m weird.
(couldn’t find a similar graph in English: this test shows airflow in cfm at a measured sound level, for a fair comparison between fans)
The main reason my case has tempered glass is that there was no white case without glass. But I like the looks now.
EDIT: The NF-A12x25 fans don’t even exist in Chromax.
