Pros: Very good airflow have had it running constantly for 6 months now with no problems going to be getting more soon

Cons: none as long as you understand its going to be loud and keep ur fingers clear of it....

Other Thoughts: Make sure if you are working around this fan with it on to keep yourself clear I wasn't paying close attention and got too close to it and bumped into it while it was running at full speed....it hurt very bad drew blood and my finger was numb from it for almost a day dont make a silly mistake and get too close.

Pros: Keeps PC idling at 27ºC and when i run crysis the max my GPU gets is 54ºC I have one installed and i bought another one for my friend.

Cons: Loud? I dont care though.

Pros: This fan pushes a lot of air.

Cons: It sounds like a turbine in my Coolermaster HAF X case. The 200 mm fans are relatively quite but this thing sounds like a jet engine in it. I've decided to go to a lower flow, quieter fan and it's working well enough to not use this fan.

Other Thoughts: If you like a medium noise fan, this is far too loud for that purpose.

Pros: value, for the air that these fans move, I dont think there is a better value. The flat out blow (thats a good thing this time). For a 3000rpm fan, they arent near as loud as I though they would be. Static pressure is good and cfm is out of this world

Cons: they are loud, but not what you would expect for the air movement.

Pros: quiet even when turning the power up and spinning fast, lots of cfm*(air movement), very reliable as i have had two running 24/7 for the last year and no change in performance or development of nasty noises etc.....

Cons: none

Other Thoughts: this is probably one of the best fans available considering the size, the schear volume of air that it moves, and the level of noise that it makes is relatively ok.

Pros: This fan moves so much air that it can be felt in the room.

I'm using mine with a Corsair H-50 water cooling system and I only need this one fan to keep my CPU's temp to 52C at full load for over 24 hours straight. My standard Corsair fan that came with the H-50 allowed the temps to rise to over 63C after 24 hours of full load testing.

I love this fan. It is by far the best bang for the buck out there today.

It is built like a tank and although a sleeve bearing, it seems to hold up very well even if something accidentally gets put into the blades. Like a finger or dust rag.

The fan is 38 mm thick so it really funnels the air through it efficiently. You may have to go to the hardware store to get screws to mount this fan.

I highly recommend this fan if you are not too concerned about a little extra noise. There are ways to prevent the noise and I'll mention them in the final thoughts.

I like this fan so much I just ordered another for another computer build.

Cons: Can be noisy. Depends on where and how you mount it.

So far it has lasted @ 24/7 running for over a year. But I've had other sleeve bearing fans die on me where my ball bearing fans have lasted for almost ever. Time will tell.

Dangerous. Don't get your fingers near this thing. It'll slice and dice your digits if you get them in the fan.

Dust....it sucks so much air that you will not need an air purifier or filter...this thing will suck all the dust in the air into your computer. So you will be cleaning the dust out more often. That's OK if you are like me and like a nice clean computer case.

My Corsair radiator gets really dusty after just a few weeks use so I pull it out every two weeks to clean it up.

May not fit in some cases. Being 30 mm thick, it requires different screws to hold it down. And as thick as it is, it may hit some parts where a standard fan would fit just fine.

Other Thoughts: If you are having a noise problem with this fan...get rid of constrictions in the air flow. I have mine mounted on the rear fan area along with my Corsair H-50. I cut out the perforations on the case and made one big hole instead of about 50 small holes. That cut down the noise tremendously. No more whistling sound but just the sound of the blades cutting through the air like a quiet whoooosh.

If you are looking for a fan to cool things down quite a bit, this fan is it.

Pros: Tons of airflow, actually makes it cooler by my desk. I have four of these in the side of an HAF 932, directly pointing into my 480 SLI setup. With the stock fan, Furmark fullscreen 1920x1080 32x MSAA samples, GPU temp on the hotter card would hit 100 degrees in less than a minute. After putting these wind tunnels in, it took almost 5 minutes running at full settings for the temp to get to 92-3, where it stayed for the next few minutes till i got tired of looking at a furry donut.

Cons: The hype is real, these are loud, real loud. Sounds like you're at the airport. I am ordering a fan control to see if i can harness the beast. I knew this going in, though so no eggs off for that. Know what you're getting into here.

Other Thoughts: VRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRMMMMMMMM!

Pros: This thing pumps like a beast. Compared to my stock fans these completely decimate them. Comp temps are surely way down from before.

Cons: It's a little bit loud, but usually music is playing so I never really hear the fan noise.

Other Thoughts: Anyone looking to keep air cooling and not switch to liquid or to have this cool your radiator or just to have it in general will love this fan. Does exactly what it's supposed to.

Pros: Pushes A LOT of air on highest setting!

Cons: Somewhat loud but what do you expect.

Other Thoughts: Bought three of em about 6 months ago, and one of them is making a grinding noise, took apart and lubed with silicon grease, but it still kept making the noise. destroyed in a fit of rage cause it was keeping me up at night.

Pros: Great quality feel (very thick plastic)
Moves a lot of air on high
Not extremely loud
Comes with a 3pin to 4pin connector
Very cheap for a 130 CFM fan

Cons: Fan controller is recommended im using this with the fan controller that came with my Rosewill RFX-120BL 120mm and it loud on high but its not excessively loud.
I put a fan grill on this i look like it cause cause some serious damage if someone got their hand caught in it or if a wire got into it.

Other Thoughts: Have this as an exhaust fan in my Cooler Master ATCS 840 right behind my Zalman 9700 and i notice a CPU temp drop of about 5 degrees Celcius when i turn it from low to high.
