SilenX EFX-12-15 120mm Effizio Quiet Case Fan

Pros: It has a nice RPM for its size and it is very quiet. It's not a silent fan but the noise is easy on the ears. Plugs into MOBO and molex. It has a good color too (red fan + black exterior). Nice price as well.

Cons: I hated the gel screws it came with. Yuck.

Pros: The fans work as advertised (so far) - they move a decent chunk of air for their noise level with the rubber mounts.

Cons: The rubber anti-vibration mounts that they provide are complete rubbish. I have 4 of these fans installed, and 12/16 of the rubber mounts snapped within a month. I e-mailed customer support and was able to get another 16 mounts sent over for $5 (no complaints about the service)... but now it's been another 2 months and 6 of the rubber mounts have snapped AGAIN.

Keep in mind that this has also been relatively light use... I have no intention of trying the rubber mounts again. And I'm guessing the sound output with screws is considerably higher.

Pros: I do not think mine is radioactive. Your mileage may vary.

Cons: 1-defective
2-defective
3-defective

bearings melt and seize in a couple months. Rattles like a 1950's window fan.

Other Thoughts: For $20 each the company offered to send me new ones.

They are really really quiet after the blade impeller falls out.

Pros: Bought 2 of these to replace the stock fans on my Corsair H80i. So much more quiet (15dBA vs. 37dBA) for the same air-flow (74 cf/m)!

Cons: None so far.

Pros: Quiet, just as advertised. Three of these are quieter than one of my old fans.

Cons: None

Other Thoughts: I replaced all my case fans with these. 2 intakes and 1 exhaust fan. They seem to move enough air because my case temp hasn't changed.

Pros: None

Cons: This fan makes more noise than it's rating of 15 dBA. In a quiet room with the fan running off a 12 volt adapter it sounds a lot louder than fans I have rate at 18.1 dBA. Very disappointed.

Other Thoughts: If your trying to build a somewhat quiet system these fans will not help.

Pros: These fans do feature pretty good static pressure and in my case the rated airflow seems accurate as well. Fans are not do not wobble and do not have problems being mounted horizontally (like sleeve bearing (cheap) fans do. Red and black color scheme looks cool in my case with red/black motherboard and ram.

Cons: These are made by a company named SilenX, and are rated for 15db noise. I used these to replace some Vantec Stealth 120's that were rated for 32db - these are louder, although not a lot. Clearly more like 33-35db, nowhere near 15db. Rubber attachment 'screws' seemed like a nice touch at first... until fans started falling down inside my case because the rubber was simply falling apart after installation (1-2 weeks, 6 out of 8 fans). After re-installing all the fans with standard screws, no more issues, and the fans are fortunately not causing any vibration noise this way that I can hear.

Other Thoughts: These are decent, fairly high airflow fans at a decent price. They are not nearly as quiet as advertised (not really 'quiet' in my opinion, but not obnoxiously loud), and the included anti-vibrational rubber installation pegs seem to wear over time and break without any cause I can see. I'd recommend the Vantec Stealth's over these, but I don't necessarily recommend against them.

Pros: It was silent when it worked.

Cons: Now its super loud now. The fan bearings went bad I believe.

Pros: Uber Silent!!
Mega Airflow!!
Best case fans I ever bought!!!

Cons: None

Pros: 1) Fan and barrings are quiet (some people think its loud because its air blowing only not the fan)
2) Good directions

Cons: none
