I have a bitaxe gamma 601 board with the following settings:

Core voltage: 1150
ASIC Freq: 525
Automatic Fan Control: ON
Target Temp: 58 °C

Is this graph normal / expected? My other ones dont seem to have temp swing as much and all 3 are sitting on the same table

a full view of dashboard. it seems like its staying hot longer. might it need new thermal paste or something?

On first glance I find it pulling 21.5 watts at the settings you specified to be a bit off.

how would i debug more? should i call the people i bought it from? my other 2 are at 18.49 J/Th and 15.99 J/Th while its still 20.2 J/Th but one is a 602 board

Are you in a particularly warm environment? Ensured the heatsink is seated properly? Otherwise I can't really see why the temps are behaving that way. 5.1V input suggests the power supply is fine. ASIC voltage is correct.

I let mine run for about an hour with the tab left open so it would log a good bit of data. You'll notice the frequency is a lot higher at 600MHz but my power draw is like 10% lower than yours with the commensurate efficiency improvement. You'll also notice the temperature is basically flat with a room temperature of about 25 celsius.

Looks like air conditioning lowering ambient temperature?
