2 Pack 4-Pin Molex to 2 x 3 Pin / 4 Pin PMW 12V PC Case Fan Power Adapter Cable, 3-Pin or 4-Pin (PWM Connector) to Molex Computer Cooler Cooling Fan Splitter Y Power (Molex-3Pin/4Pin Cable (Splitter))

Usually when I get a molex Im afraid it is going to melt because usually they are made cheaply. But this one didn't and have no issue with them. I was able to hook up many fans to my pc.

Great little connector, no issues on it. Worked as described and I added 2 additional fans to my PC with it. Wires are sturdy and connections are firm!

This adaptor cable passes +12v and ground connection from the Molex cable. This is great for powering 4-pin case fans that might draw too much current to be connected to motherboard headers. Another use is running a case fan at full speed vs. having the motherboard alter it's speed, which is how I'm using it. The cable is nice and flexible. It's a pain to get the Molex connector connected to another Molex, but ALL Molex connectors are lousy and I only use them when I have to. I recommend this product.

I have a modified orignal xbox and this molex splitter made it much easier to tap my 2 fans into the 12v power of the console rather than just solder another pin header into an already 20yr old console. Good length too. I was more impressed by the molex connector itself actually having some rigidity on the pins where rather most of the tike their just loosely in there and you have to fight it to get them to line up. Overall quite nice for what is. Saved me alot of time from making my own.

I had to buy this because the replacement fan I bought did not come with a molex connector. I thought the wires were a tad on the flimsy side and the price a bit high--but you do get two cable sets, which is one too many if you only need one. Anyway, the moral of the story is check the fan's description to make sure it's equipped with the connector you need. Then you won't need this adapter.
