Hi all,
Just an update on what has been going on over at HashFast.
First the big news - our first substrates arrive on Monday, Nov 25!
These are the high precision PCBs that lie between the silicon die and the rest of the motherboard. Once substrates arrive motherboard assembly begins, followed by board bring-up, chip bring-up and system bring-up (the process of testing chips starting at low power and working up to full spec).
For the past few weeks we have been busy assembling and testing the Baby Jet and Sierra. These images are of the Baby Jet. We are optimizing the Sierra and Baby Jet to make sure they run as cool as possible and validate our configuration's thermal management.
The video below demonstrates an airflow test of the Sierra and shows that all is working correctly in order to get sufficient ventilation flowing through the chassis. We did the same with the Baby Jet, though there is much less heat with one chip.

Hashfast Guys why in the world are you even producing two different models? It appears that the baby jet takes two cards. So does the Sierra. The baby jet vents heat in three different directions, front, top, back. That is awful and won't work at scale very well. Sierra is better, cold air in the front hot air out the back. Both take up approximately the same amount of space. Please oh please just ship all sierras, I see no cost savings for you guys because of economies of scale it will cost about the same to ship all sierra case/fan combos. For those like myself that ordered batch 1 baby jets and the upgrade module for existing customers only, it would help goodwill immensely to just ship us 2 module sierras and not this 3 way heat vent monstrosity you have dubbed the baby jet.
