4 out of 5 eggsTwo L.E.D.'s DOA

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

Pros: Very nice fan, works as described. Very quite, beautiful color L.E.D.

Cons: Two of the L.E.D.'s are not working. i'm sure i just got unlucky and got a bad one.

Other Thoughts: i really like this fan, the colors are beautiful. i will by more in the future. its just not worth RMA on a 9 dollar fan for two L.E.D.'s not working. But if cooler master wants to send me another i'll be ok with that :)

5 out of 5 eggsGreat is all i can use to describe these fans!

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

Pros: I can't even beging to list them! I have 6 of these beautiful works of art in my machine currently!
-Keeps my video card at a solid 35 degrees Celsius even when overclocked more than 200mhz on both the gpu clock and memory clock!
-Uses virtually no power! these fans have no effect whatsoever on my machine though i have 3 harddrives, a powersucking gpu, a powersucking cpu, and 3 different dvd drives!
-It looks super sexy for starters, not crazy bright like light up the room bright, but that is because the shelling is made out of black plastic, not clear like the rest of the crazy colorful lights in this world. But these fans are very bright and bring a very nice ambiance to my machine that makes me one of the happiest pc builders ever!
-First impressions count, this is my very first pc build and i currently have a compaq mobo in my rig (i know nasty) with everything else upgraded and i have to say shes starting to run like a gaming pc:)))

Cons: There are almost virtually no cons that i could notice until one of my friends came over and noticed that my pc sounded rather loud. I didn't notice it because i must have been use to it but he said she sounded like a jet engine. So i played back a few of my youtube videos and sure enough if you listened closely you could hear the fans in the background, but almost so quietly that it didn't matter.
-there is only one other thing that i could find wrong, and that is the 2 120mm i have on the top of my case sometimes tend to vibrate, but almost so quietly i didn't notice until yesterday, but i mean for that fan speed what did you expect? ultra james bond silence?

Other Thoughts: If your looking to upgrade or add style to your PC via new fans, these are the way to go. there green, their mean, and the will cool the heck outta your machine!

5 out of 5 eggsGreat for money

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

Pros: Great cost efficiency
If you use it as a case fan, you can barely hear the fan

Cons: Screws are too tight, it made me feel like I'm breaking it.

Other Thoughts: Every fan screws are pretty tight!
I don't know why..

5 out of 5 eggsGreen Machine

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

Pros: Great fan for the bucks even though it is a Sleeved Bearing whick i am not a overly fond fan, but this one with Green LRD's fit the build and the price - well what can be said - inexpensive. So far she has run in perfect style with all LED's still operational and never were to bright like other blinded by the light types.
The air flow is just as specs out as and with a 19dBA rating it is really quite all though i think it is more in the 20-22 range, but hey it is still a quite fan moving lots of air.

Cons: None

Other Thoughts: The adapter is a good addition for the person wanting to connect directly to the PS and not the MoBo - Should have come with a Coke Dispenser

5 out of 5 eggsGreat buy!

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

Pros: I bought this fan as for a new case that did not come with a case fan. This CoolerMaster fan runs quiet, and improves the cooling of my CPU by about 5-10C. It was also on sale for 8 bucks, and why not get one with lights in it also?

Cons: Nothing really, but I was hoping the lights would be brighter.

Other Thoughts: Overall, a very good buy!
