The H influx do look interesting. A little disappointing efficacy given the LM301B diodes but I guess they're using cheaper bins?

''They'' (Samsung) use their own top bin diodes.

The efficacy is only supassed by the Q-series because of they run cooler, I think you might have been mislead by salesmen copying the specs on the LM301B diode to their PCB

Yeah I was comparing it to Q series and the specs for the diode itself

Yeah, Q-series is top dog, but expensive and same PCB design as the F-series (bendy plastic PCBs with indents for mounting)

The H inFlux are nice aluminium PCBs with holes for mounting, and around 15% cheaper per diode compared to Q-series, and you get a lot more intensity and potential than you get with the Q-series.

That would mean better potential for delivering heat to the heatsinks? I wonder if aluminum channels can do the trick or if purposemade heatsinks need to be employed.

Better potential with or without heatsinks.

Level of heatsink needed is determined by how hard you run them, and how much you are ready to pay for cooling. (cooler is a little more efficient)
