2 out of 5 eggsNot meat for silent

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Red LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Nice looking fans, good LED red tone.

Cons: Lets start that my main focus is to build a PC as quiet as I can while not breaking the bank. and with red LEDs

Based on reviews some saying that the fan was loud others saying that it was OK once you controlled the RPM (which I have a fan controller), I went ahead and bought two. To my surprise even with 40% fan speed these things a are quite loud and make an annoying noise which is a bit lower when a HDD is working.

I wanted to return them but for the cost it takes to ship them back I would loose more $$$

Other Thoughts: Anyone who does not care about a silent PC its a good buy

5 out of 5 eggsNice Fan

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Red LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Good air flow, quiet and red led is a low non intrusive glow.

Cons: None

Other Thoughts: Fan is quiet installed as out-take, haven't tried as an intake. I do have another Cool Master w/Green Led(don't know model, was given to me), but is very loud as an in-take.

3 out of 5 eggsPulls air, but has bad buzzing

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Red LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: The fan looks cool, was cheap and moves air.

Cons: The fan emits a near unbearable buzzing sound

Other Thoughts: I'm using the 3 to 4-pin adapter to go into my fan controller. On the highest setting the fan has the usual "whoosh" sound you would expect. The problem is when the fan is turned down to a low or medium setting, it emits an incessant buzzing.

5 out of 5 eggsQuiet and sleek

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Red LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: I added this fan to my 212 Evo heat sink and get better cooling. These fans are quiet and i love the rich color it gives off in my case! Thumbs up for this product!

Cons: none

5 out of 5 eggsExcellent Fan, Slightly Noisy

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Red LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Red LEDs are not offensively bright. They provide a nice glow that won't keep you awake at night if you leave your computer on.

Quite a bit of air moved with these. After four years of operation I have to say, even now they still move quite a lot of air.

Cons: Loud at max speed. It doesn't bother me at all because I don't mind noise, but at half speed they are still more than audible

Can't turn the LEDs off with the button on my case, but that's about it.

Other Thoughts: I've had two of these on the side panel of my Coolermaster Scout case for almost five years now, and it's only recently have they even started to sound like I need to replace them. They run loud, but move a lot of air, even still, Oddly, turning the fan speed down also affects the brightness of the LED.

I'd recommend these, at least if they're still being made with the same level of quality. If noise at max speed does not bother you, and you want more subtle LEDs rather than ones that will light up the inside of your case by themselves, these are it.

5 out of 5 eggsWhip out the hair dryers!

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Red LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Excellent fans, period. I've used 2 of these to replace the stock 120mm fan on my Coolermaster EVO 212 heatsink/fan combo for some higher fan speeds and more "red glow" for my case. A VERY powerful combo of fans and in conjunction with the heatsink at keeping my CPU nice and frosty, as I haven't seen the CPU get over 35c on idle yet! At load, I think the highest I've seen it get yet is only 45c! (AMD Athlon X4 860K @ 4Ghz) It will be interesting to see how well this setup works at full load in the hottest room in my house during the summer, haha!

Cons: When these things get winded up at top speed, the "woosh" is very noticeable over my 6 other Apevia 120mm case fans, but to me it's not bothersome. Your mileage may vary... Personally, I have a 5.1 sound system hooked up to my computer to drown that kind of white noise out while gaming, haha!

Other Thoughts: Great CPU heatsink fan replacements, they work with my motherboard great in giving RPM listing and in speed adjustments. Great fans for the price, don't hesitate or debate, GIT U SUM!

2 out of 5 eggsMediocre at best

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Red LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: It is a cheap fan with decent looking cables. They aren't terribly loud even at full speed.

Cons: After about a month they started squeaking in oscillating manner relative to the speed I used on the fan controller. I usually have them off now because of this unless it is really hot.
