Pros: Thin and quiet. 3 manual speeds, plus it works well with DC fan controllers.

Cons: None.

Other Thoughts: Thinner and a little quieter than a stock SilverStone case fan. Under motherboard fan control, it can spin down to nice and quiet, with the LEDs barely on.

Pros: At the time I ordered this, it was the only case fan that came in Red LEDs in the size I needed. I wasn't familar with the brand but since I needed fan, to help suck the hot air out of my rig, and my side vent was just sitting there, I went for it. It's got three speeds, but I leave it on the highest because it keeps everything cool and I'm too cheap to spring for a Water Cooling system yet. This fan works well and does more than what I could have asked of it. Having the three settings is nice--would be nicer if they were easier to get to than right on the center part of the fan. Since mine is sucking air out and not pulling it in, all I have to do is get a pen or pencil to move the settings--if I really wanted to.
I had to jimmy it a bit to get it to fit in my 200mm/180mm side panel and I'm not sure if it's because of how the plastic of the fan is or if my case isn't exact (it's probably the fan because I measured the case). But once it was on, it was happy.
The LEDs are REALLY bright, and that really makes my rig because the LED fans that came with my RAIDMAX aren't super bright. So the bright red LED on the mega fan in the side brings it all together.

Cons: Like I said, the speed control could be in a better spot--if I were using it to suck air in, not out it would be impossible to adjust without taking the side panel off. Other than that, none that I have run across so far.

Other Thoughts: If you want a big fan and can't find others in the color you want, this one is a great fan to go with. It runs quietly at top speed (what makes the most noise in my PC when not gaming is if I leave my RAIDMAX case-installed case fans on high) and does a great job of keeping my GPU and PSU cool during marathon MMOing.

Pros: A red LED 180mm that works! Fans are very quite and the LEDs give off a nice smooth and even glow that isn't too bright.

Cons: The built in grill acts as a restriction and even more so if you have your own grill you want to put on.

Other Thoughts: These have a 3 speed switch on the fan. A fan controller will NOT override that physical switch. Set the switch to the maximum speed and then control the actual RPM with a fan controller if you want to use one. I overlooked this.

Pros: has great air flow.Is a nice sturdy fan.quite somewhat louder on 1200rpm's for my liking but still not that loud.Nice long power connector.and comes with a 4pin adapter.Great fan for the price

Cons: The LED's are a joke how they are put on.Its one strip of LED's glued in four spots and are in the inside of the fans housing in other words its in where the fan will spin, so with a lot of heat I'm sure these "glue points" will give.I had to cut the led strip off because it was not even fully glued and already coming off when i got the fan.

Other Thoughts: With that being said other then the LED's I would buy another one and recommended it. But BEWARE if u are buying this fan for the LED's even if u get a fan with them installed correctly i feel they will become a problem in the future and you might want to remove them anyways

Other Thoughts: Basically i would recommend this fan for the fan not for the look if u get one with the led's still attached and working beware they are bound to come off in the future do to the lack of good TEMP resistance glue and do to the poor craftsmanship of the way the LED strip is applied. And this was the only fan i bought it was not one of many.But that being said other then the joke of LED's this is a good fan for the price

Pros: Looks cool, moves decent amount of air, and "Was" Quiet

Cons: Just recently started making a loud racket, almost like it was hitting something. So I checked to make sure there was no wiring or other obstructions, which there were not. So out of curiosity, I laid the computer on its side and turned it on, the Fan was silent. Then I put the tower back vertically and once again once I powered on the machine it was loud. I tried removing the fan, reinstalling, etc... to no avail. Looks like I will have to look into RMA.

Pros: Fan matches my son's ENERMAX COENUS GUNMETAL GREY ECA3290A-G case led fans pre-installed perfectly.
Has 3 fan speed selections, moves good amount of air while staying quiet. Led Color is amazing...

Cons: NONE

Pros: Nice Fan. My first Enermax fan.
Big.
Red.
Lights are bright. Perfect amount for seeing through a tinted side window of my Fractal Design Midi R2 case. Mounted fan in top as exhaust.

Cons: Speed selector switch can only be accessed on "rear" of fan. As it is installed in my case, the switch can only be accessed if the fan is removed.
Set the speed - install fan - forget.

Other Thoughts: Would definitely purchase another.

Pros: Big air flow, 180mm mount / 200 mm mount. bright red lights

Cons: havne't found any yet.

Other Thoughts: make sure you have a 200mm mount or 180mm mount
