5 out of 5 eggsThe Best Fan

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 very well constructed
Very sturdy Plastic
You have to feel the fan comparing with other "Brands", and you will notice the difference

Cons: None

Other Thoughts: It is a very relevant fan. I was kind of shocked when I notice their construction. It was made much better than the 4-pack which I purchased before.

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

Pros: Moves a lot of air
LED's look pretty nice

Cons: Loud and annoying whirring sound

Other Thoughts: They're pretty decent fans, but are not quiet. They are easily audible even with headphones and my computer under my desk. I would not recommend these as you can get quieter fans that perform just as well for the same price.

4 out of 5 eggsGreat Airflow!!!

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

Pros: These fans produce a lot of air!!! 69.69 CFM!!! Keeps my components nice and cool in my case!!! Nice and quiet too!!! Recommended by a friend. I had to buy these because the stock fans that came with my case were just horrible!

Cons: The LEDs on the fans are a little weak. I was more worried about how much air they can handle and how quiet they were. Would have been nice if the LEDs were brighter!

Other Thoughts: If you are looking to upgrade your case fans and want quiet fans with excellent airflow, these fans do an excellent job!!!

4 out of 5 eggsGood Airflow, Not SUPER Silent

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

Pros: Alright, I'll begin with this, the LED's are pretty good. The airflow is absolutely amazing too, 69 CFM. Wow, just wow. The fans have kept my case very cold and are worth the money. Picked some up during a sale for $7.99 each. Not bad.

Cons: Some cons that I would say is that if you have them behind a mesh or a front panel, they are definitely loud. Actually, they're SUPER loud. BUT, with a little modding, (which is extremely easy) I was able to reduce the voltage from 12 v to 5 v. I had the fans connected directly into the PSU so, it was pretty easy to reduce it to 5 v with the 4 pin molex connectors.

Other Thoughts: Just by reducing the voltage that was channeled to these fans, they dropped in noise level. Out of the case, they were extremely silent, but add something that obstructs the flow, it gets loud. Would highly recommend IF you are able to lower the voltage of the fans. Great fans overall. High airflow.
