Summary: I thought the LED on the fan died. It was the PSU. So this fan was awesome for another reason. It helped me determine I had a power supply issue. Replaced the PSU. Light is on in case again, no crashes, life is good.
Pros: Runs pretty quiet. Moves a lot of air. Keeps case very cool. Will buy again in the future.
Summary: If you have a case with a side mount for one of these, make sure it will clear your power supply. I ran into a problem on a build with a Xion Xon 956 (micro atx) case with a 200mm side panel mount - the fan would not clear the power supply, near the bottom left "corner" of the fan.
Pros: Super quiet, looks great, LED is perfect amount of bright
Cons: I ran into a clearance issue, which wasn't the fan's fault. See Other thoughts:
Summary: Before purchase, check the specifications to make sure this will fit your case. Some case manufacturers have hole placement in different locations. I built this computer about 3 years ago and decided to pick up an extra 200mm fan, just in case one eventually failed.
Pros: Outstanding longevity Great performance Quiet Comes with screws [black fan does not]
Summary: I'm using this in the back of my entertainment center for cooling. It is dead quiet if you're more than 3 feet away, and it's not even loud up close. I have it hooked up to a digital thermostat, so the blue LED was an easy way to tell when it's on or not. Highly recommended!!!
Summary: The case I have has 200mm in and out. It has a 200mm outlet on top (heat rises- whodda thunk?). It supports a 5820K system that has no heat struggles at all. You can feel the airflow move quietly with good volume with this system.
Pros: Quiet as advertised. Basic, functional, No-Bling fan. That means no lights or other gaudy features. Great airflow. Use it as my inlet fan on a Corsair 650D and you can feel the air move at the inlet. I may get another for the outlet as I don't like the blue light on the one there.
Cons: I'll let you know after a year or too- if any. This replaces a stock fan that had the blades separate from the housing. I don't think this will do the same, but ....
