4 out of 5 eggsCooler master sickleflow

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

Pros: Good fan
Moves air efficiently
Quiet

Cons: Second fan was loud

Other Thoughts: So the first sickle flow I purchased was great, so I decided to purchase a second which turned out to be annoyingly loud. What happened?

4 out of 5 eggsNot so blue LED

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

Pros: Great cooling, and it's quiet.

Cons: If you're getting this for the blue lights, look elsewhere. The lights are practically non-existent. My old fan that I replaced had a better glow than this, and that was just one fan.
I have 2 of these for a push-pull effect and both of them combined don't even give much of a blue glow.
As of right now the only reason i'm still using them is because the cooling is fantastic (which is what you want) and the sound is pretty quiet with the right settings, but since I'd like to also have pretty lights I was kind of disappointed by this.

Other Thoughts: Great for cooling, bad for lighting effects.

2 out of 5 eggsRebate

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

Pros: Good quiet fans with a nice color to them. Currently using them for fans on my radiator that's within my water loop.

Cons: Company did not value rebate. Out of all the rebates sent in for the current build, this company is the only one that didn't deliver. Also, theirs was the smallest rebate of them all!

Other Thoughts: Will avoid this company in the future.

Manufacturer Response:

Dear Valued Customer,

We do honor the rebates to our customers as long as all the required information is mailed in.

Please contact me directly so that I can help to resolve this issue.

2 out of 5 eggsYou Get a Little Less Than You Payed for

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

Pros: These fans look amazing. Between the Semi translucent plastic and the vibrant blue leds, these fans look amazing in any style of build. Also, they really do move a lot of air. Even on lower RPMs they should not have any problems providing enough airflow for any build. Lastly, the cost is very reasonable.

Cons: These fans are loud! Even on very low RPMs their noise is very audible. On higher RPMs they sound like a jet is taking off! In addition, after only about 2 months, one of the five fans I bought has developed a sqeaky whine noise that is extremely annoying.

Other Thoughts: If you really don't mind loud fans, I guess these aren't too bad while they work. I would really reccomend some higher quality fans for any build because if the fans are loud, then so is the rest of your build.

Manufacturer Response:

4 out of 5 eggsgood but loud

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

Pros: Fan is working just as promised.

Cons: I thought the complaints about the noise were by those that wanted no sound at all but I was surprised at how loud this fan is. Unless you run it at a lower speed it has a very high hum to it and I probably will purchase another fan and keep this around just in case I need a quick replacement.
