That, was a bargain.

Can't get over how amazing this Blackberry camera is !
Quick write up on findings so far. They are heavy. That isn't surprising, given their nature. The shroud around the blades is very thick (the white part) mostly because it needs to carry all of the LEDs. The outer frame though is nice, and reassuringly thick. The grey area on each corner is rubberised, meaning they shouldn't vibrate.
They are pretty quiet but then right now they are meeting no resistance. However, I did catch my finger in one (natch) and was surprised at how heavy the blades were.
I've seen the motors in a review on YT and they don't look huge. I would surmise they are better at flow than static pressure, just given the motor size. However, that doesn't matter to me as I will be running push/pull on a 120mm AIO that will be cooling a 2.4ghz 10 core Broadwell. It's not known for being hot, especially at the clocks it runs at.
Overall? very happy. The hub thing is a real bonus, it means you literally need one single Molex to power the whole lot. I saw a video of these running side by side with Corsair Maglevs, and tbh? you would be hard pushed to pick them out. Until, of course, the Corsairs light up in the centre, which these don't.
