Pros: I picked up two of these fans in June of last year. I swapped them out for some fans in my aquarium light fixture because the stock fans sounded like a hair dryer. Needless to say, they work have been running for 10 hours a day for almost a year with no increase in volume. I would highly recommend these fans for both their airflow and the fact that they are so quiet.

Cons: None

Overall Review: At $8, you can't beat the price.

Pros: This moves a lot more air than a typical stock case fan, it truly is extremely quiet in reality, and the price isn't outrageous. That's all I need to buy it.

Cons: The color might not look quite right in all cases. Yellow fins in a black case with blue accents for example would like sort of odd.

Overall Review: At the moment, the larger 92mm fan is cheaper for some reason. It moves more air and most cases can fit a 92mm fan so keep that in mind.

Pros: So quiet you'll think you're dead Silicone attachment posts actually end up being really cool Instructions are well-written and a model for how tech instructions should be

Cons: Slightly harder to mount with silicone posts when case is crowded

Overall Review: The silicone posts are weird but once you get one in you realize how brilliant they are. Don't be shy pulling them WAY out until they snap into place. They do make it harder to mount fans which are in tight corners or smushed next to each other; I had to use needle-nose pliers in a couple of places to grab the silicone nub and stretch it through the little hole. So IF you have a crowded case, expect to spend a lot of extra time getting them mounted if you use the silicone mounts. Worth it, though. I just put in four of these and they're stunningly quiet. I had a monster in my room and now it's like wind off in the distance. The instruction/installation sheet is beautifully written. I have to say this since I'm so used to badly-translated "puts red to blue sides whole" chinababble. They not only give clear directions, but take the extra step of explaining why they took certain design steps, like 3-pin vs 4-pin power header.

Pros: Quiet, Very Nice Looking, Decent Performance, Overall Satisfactory!

Cons: As with anything could always be better, in terms of silence these are Very quiet, but still one COULD say they need to move more air, but with that comes sound... which is more important?

Overall Review: I have been very satisfied with these, my computers all sit in another room and noise isnt much of a concern, but I still find myself ordering more for the rest of my computers, In fact I may change all the fans over to silenx.

Pros: Quality, good price, attractive, quiet, good air flow

Cons: NA

Overall Review: Great fans I bought 6 of these to replace the fans in my servers. Amazing is the first word that comes to mind. They are silent and keep my system the same temp as my old fans. You will not be sorry with these fans. FYI to get the 3 year warranty you have to register the fans online!

Pros: I replaced 4 x 80mm fans in my full tower case with these fans, and the fans are no longer the noisiest spindles in the PC. I now hear the hard disks more than the fans!

Cons: A 3-year warranty if you register on their web site, a 1-year standard warranty if you don't. That's nice, except THERE IS NO PLACE ON THEIR WEB SITE TO REGISTER. Try it yourself. Also, the warranty terms state that the user is responsible for shipping and handling. What a joke. I can buy a new fan from Newegg for less than their shipping and handling charge.

Overall Review: Total *ul**hi* with the warranty. I knocked them down to 3 eggs because of that. A reputable company should stand by their products with a solid warranty; not one that uses loopholes. I have placed a repeat order for more of these fans, as they are just so darned quiet and provide adequate airflow.

Pros: Moves a good amount of air for how quiet it is. Can't even tell that it's running without putting my hand up to it.

Cons: Pricey, but you get what you pay for. Installation with the rubber mounts was difficult in the front of my case since the hard drive cage couldn't be removed. Not the fan's fault so no eggs off. Felt like I could have ripped the mounts apart while pulling them through the holes, probably why there's an extra one included.

Overall Review: One of these in the front and a 92mm model in the rear of my case. AMD FX-6100 idles at 21C!

Pros: - Silent - Good airflow - Rubber fan mounts included so no vibration - Cable has molex or 3 pin connector option built right in. - Colors common to a lot of gaming series boards these days

Cons: - No grill cover?

Overall Review: Honestly best case fans I've bought. Weren't too expensive, but just a couple dollars more then cheapo ones. Included screws AND rubber mounting plugs. Also for once I didn't have to shuffle around cables because I had the option to use 3 pin OR molex, very convenient. "No grill cover" isn't really a con as pretty much no fans come with that anymore, but figured I'd throw that in there since there's really nothing else to critique.
