They would fit but its inly rated for 2.1A per port. So the CompacFs wouldnt be able to run full speed

Ive got the bitcoin merch usb hub which is also 2.1a per port

Im only running 4 compac f's. If you dont use all of the ports, does that mean you get extra amperage in the ports youre using?

right now, im running at 400mhz, and fluctuating between 260-310 gh/s. I feel like i can push it a little further. Ive got the 3d printed fans on each one, AND 2 artic fans. I dont feel any heat coming off them at all.

What do you all think? Should I push them farther? How do you know how fast you can take them? I dont wanna fry em out. or should I just wait and get the gekko science hub?

BTW, thanks for all the great info here! my first post. Only been into btc less than a year, and I just began learning about mining.
