Good video. Basically this thing throttles, pretty badly in an OPEN bench rig.
The one criticism I have about this video is that Jay does not state the obvious, which is that he has been able to resolve the throttling issues, by adjusting power, temp, and fan speed limits, but that is at STOCK clocks...which means that the actual headroom for overclocking will be extremely limited, especially in real cases, and will essentially need the fan to run at very high speeds (possibly 100% constantly).
Either way, I suggest waiting for AIB vendor versions.
