If the shop that machined it had been able to cut it right exactly to my CAD model, it would have weighed 1.4 lbs, compared to the stock Magnesium fan weight of 1.2lbs. While it would have been nice for the fan to have been lighter, I'm certainly not complaining about the weight... this is a prototype, and fan weight is not a concern for me as this time. The output and efficiency are though and this fan is perfect for testing those attributes.
