Can i use this USB hub for 2x gekkoscience compac f?
I need 12V/3A each usb port?

The spec for that HUB says 2.4A per port (12 watts per port)

So with the 36Watt PSU that comes with it, it should be enough to run 2 of them and enough power left for fans provided you dont over-clock them.

Anyway, I found this info a while back that gives a guide to load Vs clock rate for the compac f.

Code:

Clock : Hub Power : Hashrate
400Mhz : 2.0A : 200GH/s
500Mhz : 2.75A : 300GH/s
545Mhz : 3.0A : 366GH/s
600Mhz : 3.3A : 400GH/s
700Mhz : 4.0A : 460GH/s
800Mhz : 5.0A : 550GH/s

Typically I run mine at 450Mhz, it seems most stable at that rate and averages around 275-320GH/s

Higher clocks and it starts to get very hot and unstable even with forced air cooling. Don't be tempted to overclock too much it'll get too hot.

That means even if i use 5A with a good cooler (maybe a 120mm from noctua) and make a dyi cooler to use it in both miner together it will be run instabile?
