Yeah i Know, i've had cheapo 0.5$ led fans, they ran silent for a year then BZZZZ , plastic fans hitting base of fan.
What is CFM? They are rated at 33, but on Corsair RGB they are rated 43?
It seems like these are the "Generic" are similar to this one's HereYoutube review (at temperature diffirence between Corsair and AMZtronics)
Well as you said, you lose software control, airflow,( but the leds are actually good, i have generic ebay led strip and they are stunning).
Just asking for opinion thats all
