Review on Noctua NF-A20 PWM: The Ultimate 200x30mm Brown Quiet Fan by Alfred Paiz

I got it as a replacement for the front 200mm fan that came over the case with my fantex entu. The fan does not fit as it is thicker and larger than the one supplied. But it's a little quieter when running at full power and moves more air, which I find to be more beneficial than having to use the rubber mounts it uses as screws to hold it in place. Unfortunately, it doesn't really fit my case, but it does the job quite well. And in case it doesn't work with hard drive trays. So it's a mess. While the fan is very quiet and does a good job, it's a bit clunky and can be measured before it's placed in the case. If you can't put something in a place where it doesn't have to hang and get in the way of other components, it's better to use a thinner case or the standard fan. But if you have a case with free space for it, then this is a really good fan.
