easy install, well made.
Glow is only really visible on one side of fan so if you want to use as intake, glow will be outside case/ and not inside. And vice versa for using as exhaust.
Does the trick.

keeps cool'
led is dim and can barely see it in my mini itx case with a window. uncontrollable speeds in cpu.
I did not like the speeds this fan was hitting. 2000rpm without throttling. the fan got hot itself at this speed...literally.

massive air-flow
pretty silent
The red led color seems to be intense on the image for this product. Actually, the light is not that strong. It will not be enough to light up your entire case, so do not expect too much
Would buy it again in conjunction with others kinds of lightning to light my entire computer case

Red LEDs.
Keep the computer nice and cool.
Quiet, especially when you take into consideration how well it does its job.
Cannot seem to control the speed of the fans when they're connected to the CPU fan header on the motherboard, but when they're connected to SYS FAN headers, then it is possible.
These fans work perfectly with my case. I bought them primarily because of their price and the red LEDs but they work great. They keep the case cool and that's what matters most to me.

Red, Quiet
The girl I installed this for loves the red lights! Best valentine's day gift ever she says! Oh it's quietly blowing air like it should.

Price when on sale, pushes fair amount of air
Noisy, LED is a bit dim
Pushes a lot of air, but also generates noise that reflects how hard the fan is working. I'd like the LED on the fan to be a bit brighter.

Experience: 1 Months


- Great price
- Pushes a lot of air
- Looks great
- Included adapter
- Loud
Cheap, good looking fan. Overall a fantastic value. Used this and the blue versions multiple times. They've always worked great.
