Y spliter help for pc fans

[Brock Tremel]

whats the best 3 way y spliter for around 10 usa dollars that will ensure a safe usage!
( they are 2 x 120mm Side Blue LED Fan Coolers by sentry)

Here's the one I installed and works perfectly for $4.99 delivered to my front door. http://www.newegg.com/Product/Product.aspx?Item=N82E16812162059&cm_re=fan_splitter_cable-_-12-162-059-_-Product. Silverstone makes products that are second to none....IN MY OPINION OF COURSE.

Thank you yes they are a great company in my opinion to!

That splitter certainly will work for you. But there are two other issues you should think about.

1. General "rule of thumb" is that any mobo fan header can power two fans, but not more. So using three as you plan is risking POSSIBLE problems, although it may still work OK.
2. Those fans are 3-pin design, as far as I can tell. Look closely at them. Are there three wires coming out of the fan motor, and a connector on the end with 3 holes? If yes, you should know that you can only control the speed of 3-pin fans when they are plugged into a mobo port that is also a 3-pin design (Voltage Control Mode). Many mobos have both 3- and 4-pin CHA_FAN ports. SOME mobos with only 4-pin ports can be set in BIOS Setup to make those ports behave in true 3-pin (Voltage Control) Mode, rather than 4-pin (PWM Control) mode. If you connect 3-pin fans only to a 4-pin PWM Mode) port, the fans will run at full speed all the time.

Theres 2 wires coming out of the fan cable, and does it really matter if there always at full speed? i game mostly and edit video on my pc.

Oh, 2 wires! So now we ask, what does the connector on the end look like, and where have you been plugging it in?

A common 3-wire or 4-wire fan connector is about 3/8" wide with 3 small holes in a straight line (or 4 and a bit wider). The plugs fit onto fan ports on a mobo with small pins sticking up. But most fans with only 2 wires end in a connector that is about 3/4" wide with four larger pins (not holes) in a straight line nestled inside a shall, but only 2 of the pins are actually used for the 2 wires. This type of connector is known as a "4-pin Molex" and plugs into a mating female output connector on 4 wires directly from the PSU. This PSU output connector originally was widely used for IDE hard drives and still is used for some optical drives.

So, if the fans you have with only 2 wires have those larger 4-pin Molex connectors on their ends, and you plug them into wires directly from the PSU, you do NOT need a fan splitter of the type linked above. In fact, that type of fan with that type of connection never has any speed control by the mobo - they only run at full speed, unless you change their wiring connections. For that fan type, you need a different splitter to make several 4-pin Molex outputs from one. Moreover, such PSU outputs have MUCH higher power ability that a mobo port, so there is no real limit on how many fans you can connect to one output by using splitters.

Here is an example of a 2-from-1 Y-splitter of the 4-pin Molex type:

If you buy two and plug the second into one of the two outputs of the first, you now have 3 outputs for fans. If you buy three and stack them, you can make 4 outputs from one.
