Price History (Excluding Tax & Combo Deals) History:


from completed build First gaming build (update)

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 Beginner Blue Beast

A bit noisy without a fan controller to turn them down.

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.

from completed build Northwind

These fans are holding strong and are not that loud at all. The lights are bright and the blue aura is beautiful in the dark. They move more than enough air to keep my CPU, motherboard and RAM nice and cool. Temps never get way to high and they seem to have no problems with the stickers flying off the center (as pointed out by other builders). I only want to point out that if you want absolute quiet running: Get a solid state drive with as little fans as possible in general. Fans will make at least a little bit of noise, and to me these aren't even half as bad as some systems I have been around. It depends on how anal you are about such things.

from completed build First Budget PC

little loud at full bore but still a great fan if you don't want to spend a lot.

from completed build 14 Year Old's First Build

Really nice, I got two when they were on sale even cheaper and there relatively quiet. The lights go well with the NZXT HUE LED's i have in my case and even though i only have 3 fans (2 of which are the blue cooler masters and one a crappy one that came with the case) these things keep the case and the components inside it cool to the touch.

Nearly perfect! It looks really cool, and moves a pretty good amount of air. It's not exceptionally quiet, but it's not loud, either. The only issue is that there wasn't any easily visible arrow designating the correct direction to install it, so I installed it the wrong way first time around
