Case cooling is becoming more essential these days. Quality fans with better airflow inside your chassis will give you a more stable system. The SickleFlow 120 with 2000 RPM is no doubt one of the best case fans in the market.

It's my firm belief that, when ever possible, utilize board control of fans. The boards censors know more than we do about what temperatures to avoid and what are ok. So, letting the board decide to have them on high or low or even not at all is much better. I have an ASUS ROG Maximus VIII Hero motherboard, and it utilizes a fan control system that will go as far as turning fans off completely when they're not needed. That is as silent as you could possibly get.
If you don't have on board fan connections, and are not wanting a loud fan, you're either going to need to buy a fan with a speed controller already wired in, or by a fan control module to set the speeds yourself.
Pros: exactly what we paid for and what the product was described as. Does the work very well, and delivers on low speed silence promised. Doesn't end up all that loud when on high.
Cons: the attached fan cable is pretty short, so if you have a long distance to go, or are worried about keeping cable management looking perfect you will need an extension cable.
Bottom Line: A smart choice and super quiet! Can't believe I waited this long to replace the original noisy fan.

I am just an Amazon Prime member who reviews products as a hobby. I author my reviews seriously and will only provide my true feedback. Thank you!
And Yes I have used them on my computer builds and fan replacements!
(Appearance) Clear smoky plastic color helps Capture and reflect out the Blue Light coming off the LED's (My Favorite Color BTW)
(Parts) They do give you the Adaptor so you can easily plug into the computers power supply
(Sound) Very Quiet, Yes you can hear the sounds of air passing and sight Vibration, but quieter then other fans I've tried
'Any less & I'd be wandering if its Spinning!'
(Lifespan) I have not had any die on me yet! so this might Update!
'But I try not to let dust build up, because that will kill your fan/(s)'
My Next Project possible including these fans
I might make a homemade Laptop cooler If I can make it Sturdy but not an ugly sight!
As for the review: These are the cheaper 'Sleeve Bearing' fans, not ball bearing. They're quiet and I usually get an easy 5 years of use even in harsh dirty environments with the cheaper sleeve bearing fans. The blue colored LEDs are a nice touch too as all 4 of these got installed on the side of my case; it looks like a cool drone now...
Unlike most 120mm fans, this one pumps out a lot of air, consuming 4watts vs slower 120mm fans using only 1watt.
Pros: Huge amounts of air. Quiet for how much airflow you get. Reliable.
Cons: Higher power consumption than slower fans (+3watts). Louder.
If you want high airflow without much noise, this fan is it.
I just finished installing four of these on my H100. Four of them are noticeably quieter than two of the Corsair factory fans. I've ordered regulators to spin them down to medium output, but after listening to them for a few minutes, I might not even want to.
Under sustained load, the ASUS tool reports a four degree Fahrenheit drop on the first CPU core using these. I haven't tried using only two for an apples to apples cooling comparison with the Corsair factory fans. But, four of these do slightly out perform two of the higher db Corsairs.
The blue LED is dimmer than some other fans I've seen, but enhances the blade edges and creates a pleasant glow against the type of plastic used.
This fan is the one which comes on one side of the Cooler Master Hyper 212 EVO CPU cooler. If you are looking for a second fan for that cooler, this is the right one.
I was going to remove one star due to the lack of built-in speed control. But, for the price, you can buy one and still be under the cost point of the big name fans everyone talks about.
