What cable to use to connect all fans to Power Supply?

post #1 of 19
Thread Starter 
My power supply has extra Molex and SATA connections, so what cable do you use to connect all fans (fans have 3 pin holes) to the Power Supply through Molex or SATA? I would prefer a cable that allows multiple fans to connect to a single Molex or SATA connection if that is possible. If you could give a NewEgg or Amazon link, that would be helpful.

I also found a 2 connection for 3 pin fan to a single connection, but I'm not sure if that would cause too much stress on the motherboard. Would those cable listed below work and are they safe to use? Also my motherboard has very few fan connections left, so I would prefer to connect the fans to the power supply.

Below is the 2 connection for 3 pin fan to single connection:

One of these would be ideal - [ame="http://www.amazon.com/Sunbeam-MFPP-Multi-Fan-Power-Port/dp/B000HZM1VE/ref=sr_1_6?ie=UTF8&qid=1312030426&sr=8-6"]http://www.amazon.com/Sunbeam-MFPP-Multi-Fan-Power-Port/dp/B000HZM1VE/ref=sr_1_6?ie=UTF8&qid=1312030426&sr=8-6[/ame]

Just connect one molex connector from the power supply into it and plug your 3 pin fan connectors to the 3 pin ports on the hub.

Thanks for the reply, repped. That looks good, but my fans are spread apart in the case and the fan cables are only like 5 inches long, so I don't think all my fans would be able to reach to that hub. Are there any alternative to that and any that are cheaper (that one cost $12.50 with $5 shipping, so its kind of expensive)? I prefer the seller to be the official Amazon seller or NewEgg, so I can get free shipping, but if that is not possible, then its fine. Other website are okay too as long as its a legit and reputable site (like TigerDirect or something else).

Would these fan extension cables work too (not sure if it is the correct cable)?

http://www.newegg.com/Product/Product.aspx?Item=N82E16812189004

Those cables at NewEgg are cheaper because when I buy multiple cables, the cost of each cable goes down.

Also, for Zalman connector cable you linked, its said it can connect 5V or 12V power to any additional fans, but are 2 white cable and 1 black cable. Are there two 5V and one 12V or vice versa? Also, how can I check if my fan is 5V or 12V? Can you connect any fan to any of the 5V or 12V and it will work or does it need the proper voltage of the fan to the connection for it to work?

I think these might be good because I won't need to buy extension cables for them, since my power supply Molex cables should be long enough.

Below is the 3 pin fan to 4 pin Molex cable I found:
http://www.newegg.com/Product/Product.aspx?Item=N82E16812189119

The shipping is $2, but it cost 50 cent extra shipping for any additional cable you order. The NewEgg comments said that the cable has both a male and female Molex connection, so it should work fine with my Power Supply cable. Can anyone tell me if I picked out the correct cable?

Yeah that extension cable should work too.
For that zalman cable it has 2 5v connectors and 2 12v connectors. It might say on the label on the fan what voltage it uses. Fans can be connected to the 5v connector to reduce the noise they produce or the 12v to increase the airflow the fan produces but increases the noise they produce.

That's quite a good option actually. The 2 molex connectors provide a pass through option. This allows to you power a fan while keeping the same amount of molex connectors that you currently have.

Thanks for the help again, repped. I think I'm going to go with the single 3 pin fan to 4 pin Molex cable option (the last link I posted) because it allows for the most flexibility and I don't have to buy any extension cables.
