What and what can be removed from motherboard to lower the energy consumption while mining? What is the possible lowest energy consumption someone can go? I'm using a second generation motherboard i3 2130 3.4ghz and 3x gtx1660 Ti
the cheap mobo without riser integrated mobile cpu, check the lowest ssd consumption, low voltage ram, disable audio, use titanium psu at half power, and ambient temperature is the key
if your place is hot, then 3M liquid is good enough to cooling all parts except psu, atleast you would see 20-30% power saving with this liquid
