My dell optiplex 755 needs a new fan

[charlescoke]

I bought 2 generic fans for the optiplex 755. They have different plug in. I was told I could use the power supply. I don't see and place tp plug them in. Any help

Hi

you can get adapters for fan to molex connectors (assuming you have any spare molex connectors)
some fans have 3 pin others especially for CPU heat sinks have 4 pins and some fans have molex connectors
