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.

5 out of 5 eggsWorks great!

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

Pros: Moves air great and runs silently. The red LED goes with the exhaust fan which also has red LED so the inside of my case is a nice ambient red.

Cons: Nothing too bad about this. It works like it's supposed to.

Other Thoughts: Other reviews I've read say how noisy it is. Proper installation is the answer. I bought two and put both as intake in the front of the case. There's no rattling and no grinding.

4 out of 5 eggs

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 TON of air
Nearly silent.. see other thoughts
Red LED's

Cons: LED's are a little dim

Other Thoughts: this fan is silent as long as there isn't a filter or some sort of grille put right in front of the air path, if there is all you will hear is air being sucked in.

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

2 out of 5 eggsDisappointed

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

Pros: Pushes a LOT of air. Way more than any stock fan I've used. Red LEDs look really nice, good color, not over powering. Pretty quiet for about a year.

Cons: Lasted *just* over a year. 1 year and a few days. If its mounted vertically, it makes a noise like one of the blades is heavier than the rest. If horizontal, it makes a noise similar to the crackle you hear from a HDD. I'm assuming the bearing is shot, which is a real disappointment since the warranty does nothing after a year.

Manufacturer Response:

Hello,

I am sorry to hear that the fan only lasted about a year for you. Please note for any possible future issues that often we will make an exception for you if the product is only about a week outside of the warranty.

4 out of 5 eggsCooler Master Red LED 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 fan, good airflow. Look great in the case.

Cons: Bought 6 of these for my full size tower. One of the fans sounds makes an annoying grinding sound. So I either have to send it back and pay almost what I paid for it to RMA or just deal with the annoyance.

Other Thoughts: Looks great, and definitely a good value despite the one malfunctioning unit. I would still recommend this fan to anyone looking to increase the air flow in their tower.

2 out of 5 eggsLasted a Year

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

Pros: Good high speed fans and can move a decent amount of air flow.

Cons: First and foremost, the installation was a bit of a pain, I'm never a fan of fans that have to have the screws threaded into the plastic. Makes for a difficult install (at least in my opinion).

Secondly, within a year the center fan in the top of my case started to make rattling sounds like the bearings were going out. When I pushed the top of the fan down, the rattling stopped. So to fix the rattling, I actually applied pressure to the top of the fan before putting the top of my case back on. This caused one of the fan supports to snap (very little pressure was applied) causing me to simply throw the fan out. So now I'm running with a missing fan for pushing my CPU heat out.

If you're looking for a fan that can still do 2,000+ RPM, get something a little more high end than this one, it'll last a lot longer.

Other Thoughts: I've been a long time fan of Coolermaster (I own a Cosmos II) so I don't think it's Coolermaster's fault this went all bad, I own a second Coolermaster fan of the same type and it's got no issues (though I think I hear a rattling every now and then). I think these fans were designed to be cheap and be something that isn't used in a high end gaming rig like mine. Going to be ordering another type of Coolermaster fan, hopefully they last longer than this one.
