Now you say you can hear the SP120 QE at 4-5ft, something is not right? What fans are where and on what cooler? I know the 550D case very well, and one that is the biggest disappointment I've worked with.
Im not disagreeing that the Helix fans are good. For coming with the kit, and the price they go for, they seem to be great. However, I was stating that I doubt they can be "dead silent" at 1300rpm, since no moving object is "dead silent", and the Corsair SP120 QEs are generally known to be very quiet, but I didn't personally think so. I also don't mind spending more for top tier when it comes to certain things like noise.
Just saying, I wouldn't go as far to say the Helix fans at 1300rpm are dead silent, because there is no factual information behind that. Its not physically possible. Noise is generally based on a person and condition basis.
The tone of the above is not meant in any foul manor, just stating I disagree with the terminology that was used.
As for the 550D, I was fairly happy with it over all, however it (and the Antec P280) have shown me that noise dampened cases does not really mean quieter. Finding a balance of getting the most air flow from as few fans as possible, and trying to balance for speed/noise of the fans, will give quieter results then a case that is dampened but doesn't have much airflow. Because under load the CPU/GPU fans will need to spin higher.
So my next project is a Phantom 630 with Noctuas.
