no shit Sherlock (that's why a personal opinion is needed)
I'm done here.
You were "done here" before you started. Your immaturity rang supreme.
And you've still missed the point. OP asked What the LEDs on Fans look like, not IF "blueballs" likes LEDs on fans.
So, no, your personal opinion was not needed.
You're wrong in every single word you uttered in this thread, except for being done here. That you are.
Now, onto something that matters...
@Biferony - The best answer here is to watch YT videos of the fans in action. I know exactly what you mean; not only is it hard to evaluate what it'll look like, but many times the same fans might even seem different. There's a reason for that. But, again, just search YT for the particular fans you're interested in, or just comparison videos (there are plenty). I had this same question a few years back but back then there weren't as many videos, so you're lucky. The Internet wins again.
Good luck mate~
