5 out of 5 eggsCooler Master SickleFlow 120

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

Pros: This thing moves air! And the red LED looks amazing.

Cons: I use it for CPU cooling and it tends to be somewhat loud. Although the sound doesn't bother me too much. That's why I gave it 5 eggs.

4 out of 5 eggsGreat fan for push setup

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

Pros: This fan is really powerful and quite when running as a push setup. The LEDs create a nice effect, but don't create an eye sore.

Cons: In a pull config... The things are turbines! I guess it's the fan blade design, but their soo loud!

Other Thoughts: If your using them to push air though a rad, heatsink, or out of a case, there great. If you want them as intakes pulling, they become turbines!

5 out of 5 eggsLove these fans

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

Pros: Move air very nicely, I use 2 of them side by side as exhaust fans to keep my computer cool and they're effective.

Cons: If only they'd run faster than 2,000 RPM, then they'd move even more air.

Other Thoughts: I just ordered 3 more, I like them that much.

2 out of 5 eggsLoud and Dim

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

Pros: - eh, nothing really comes to mind, considering all the other offerings out there

Cons: - really poor LED, super dim, doesn't really do much for effect
- didn't play well with NZXT fan controller, super loud and obnoxious...has something to do with under-volting, I guess

Other Thoughts: Don't get sleeve bearing fans if you want to run them horizontal. Learned the hard way, go for hydro bearing, or something that won't get crazy loud.

Manufacturer Response:

Hello Adam,

Our apologies on the fan not meeting your needs and expectations.




Sincerely,

4 out of 5 eggsSolid

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

Pros: They work, red LED lights, quiet, come with molex adapters, 3-pin

Cons: Cords are very short
Red LEDs aren't as bright as I had hoped
Screws are hard to put in the first time (to be expected on new fan install)

Other Thoughts: If you plug this in through molex, it is LOUD. In my book it's always performance over anything else, but when I unplugged my one fan from molex it was a breath of fresh air (I bought 2, one is plugged into the board). Just a warning, it is unbearably loud using molex. Otherwise, good fans.
