In my system cabinet the exhausts fan (120mm, 3 pin connectable by 3 color cable-red,blake,yellow), I connected directly to power supply (smps) as red to red, black to black and yellow to yellow of smps –but the fan rpm is very slow or insufficient to cool my system.
So I connected as follow to increase fan rpm
Fan 3 color cable Smps 4 color cable
^ ^
Black---------------------------black
Red-----------------------------yellow Black
Is there any wrong to my system/smps ?
