4 out of 5 eggsQuiet fan but not much airflow

This review is from: Cooler Master Sleeve Bearing 140mm Silent Fan for Computer Cases and Radiators

Pros: Extremely quiet

Cons: Doesn't seem to push a lot of air

Other Thoughts: If loudness is your concern, this might be the right item. But if you need a lot of air, get something else.

5 out of 5 eggspretty quiet

This review is from: Cooler Master Sleeve Bearing 140mm Silent Fan for Computer Cases and Radiators

Pros: Using it in a HAF 912 case with 2x Cooler Master MegaFlow 200s and the stock 120mm in there. This one is pretty quiet. Maybe a little bit of bearing noise but not really a big deal.

Cons: Could be even quieter!

5 out of 5 eggsFan arrived in case with broken blade but NewEgg replaced it

This review is from: Cooler Master Sleeve Bearing 140mm Silent Fan for Computer Cases and Radiators

Pros: I sent this broken fan in a separate, smaller box with an RMA number to be replaced, instead of shipping the entire case back to them. They appreciated the effort, but they really don't replace parts that way usually. They made an exception, however, and shipped me the replacement fan. Way to go, Newegg! Another happy customer!

Cons: Fan arrived in case with broken blade.

5 out of 5 eggsWorks and it's pretty quiet

This review is from: Cooler Master Sleeve Bearing 140mm Silent Fan for Computer Cases and Radiators

Pros: Works
Pretty quiet
Good build quality

Cons: None so far

Other Thoughts: I haven't tried out lots of "quiet" fans, so I don't have much to compare to, but my computer is pretty quiet, and I have had no temperature issues.

1 out of 5 eggs75% DOA RATE

This review is from: Cooler Master Sleeve Bearing 140mm Silent Fan for Computer Cases and Radiators

Pros: Cheap.
When it works it works well.

Cons: 3 of the 4 I ordered arrived DoA. The blades had actually broken off the motor.

Other Thoughts: When it worked it was great, but with a 75% DOA rate I don't think I'll be buying again.

4 out of 5 eggsTwo years, still going strong.

This review is from: Cooler Master Sleeve Bearing 140mm Silent Fan for Computer Cases and Radiators

Pros: Pushes good amount of air, pretty quiet. Inexpensive.

Cons: On full RPM it can be pretty loud. I also think a bearing might be going out but it's still pretty good. No LEDs because LEDs make everything more awesome.

Other Thoughts: These are pretty cheap but decent quality for the price.

2 out of 5 eggsSuprisingly loud

This review is from: Cooler Master Sleeve Bearing 140mm Silent Fan for Computer Cases and Radiators

Pros: Reasonable price, good airflow.

Cons: Bought two of these for my Carbide 500R's top bay, and after installing them I noticed an annoying thrumming/humming noise; imagine ambient machinery in a video game. Yeah.

I had them hooked up to a fan controller (currently d/c'd), but will try a direct plugin to a power connector tomorrow when I get a chance to see if that fixes the issue, as I think I read someone else having a problem with them when they were undervolted. Will report back with findings.

Manufacturer Response:
