I wanna DIY my grow led with 4 3070cree cobs.. I will power them at 50w each.. My question is should i Use passive heat sink or should i use pc cooler heat sinks
?? I have tgl60 and he has passive heatsink
, it raises my tent temp by 3c..And in summer that is too much.. So should i use passive or active heat sinks?
