2 pin female to 4 pin male molex, OK?

[NHguy]

Hi Guys,
Hopefully my last question. Thanks for your prior answers and understanding.
The "fan only" cable that came w/ the power supply has 2 pin female molex connectors. The two front fans in the case are 4 pin male. Is going to be a problem? And if so, can I assume I can get an adaptor easily?

No need for an adapter. Those "fan only" power connectors are specifically for fans with a 2/3-pin connector. But if your case fans already have standard 4-pin molex power connectors, then you can plug them directly into the regular 4-pin molex connectors that PSU's have. Nice and simple.

In other words, the 4-wire molex connectors supply 5 volts and 12 volts.

The fan only needs 12 volts; only two wires are needed.

Yep, just the two wires are used by a fan. But many case fans come with the standard 4-pin molex connector so that you can hook them up without the need for any adapters. Makes it easier for people who don't know why there are so many different power connectors in a computer. And don't even get me started on proprietary power connectors!!
