Price History (Excluding Tax & Combo Deals) History:


from completed build First gaming build

Got these because they were blue and cheap. The only thing I don't like about them (this may be true for all LED fans but idk bc these are the only ones I have) is that the LED brightness is directly related to the fan speed i.e. at system idle there's no light. If i'd known that i would've just gotten some stand alone LEDs and Noctua fans

from completed build NeoBlue

WRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR Yeah it gets loud if you turn it all the way up. LEDs are a brilliant blue! Love the color on this one

Keeps good airflow and looks cool

from completed build All work and no play, NO WAY!!!!

they are $9 bucks but the case is small and they move air

These fans were super cheap for a fair amount of airflow, plus they are blue which I love. They are quiet even under higher load. I've set them to run a bit higher than default, which keeps the whole environment nice and cool.
