5 volt 4-pin molex doesn't completely work
Posted: Sun Mar 04, 2018 4:44 pm
i have a corsair case with 3 front fans with blue led and a top 20cm fan (i think) all use the old legacy 4 pin legacy.
there are 3 such fans and my own 2-pin 120mm fan, the 3 fans each have a 4-pin with a pass through
using a pass through molex 4-pin with 3-pin fan connector i connect 2-pin 120mm fan
using a pair of pliers i cut throught he very hard plastic and then reversed the connection on the power molex from PSU a corsair PSU to fans, from power to the first one, but the other 2 are normal.
now the 2-pin 120mm fan works fine, it whirs and is almost silent.
the led fanlights up very dim but visible
but none of the 3 case fans are running.
at normal 4-pin molex alignment it works but too noisy for my taste.
can this be made to work somehow?
