I have 3 fans already (3 120mm normal fan and a radiator) and my motherboard 3/4 pin conectors are already being used.
I will buy 3 new fans but i have no more motherboard connectors so i will buy a 3x3 pin connector adapter to molex.
I want to know how many watts does a single molex support and if the 3 fans will run at full speed in only 1 molex
