Windows 7: A noob question

A noob question

My mobo has only 1 chassis fan connector. Let's say i want to connect 3 fans to it. How do i go about? I read somewhere that i need a fan cable splitter in order to achieve this. Is it reliable? Any other way to connect them?

My mobo specs : ASUSTeK Computer Inc. -Support- Specification P5G41-M LE

You could always buy some fans that run off the PSU instead of the Mobo? Sometimes the headers on the motherboard don't meet the power requirements of more powerful fans.

Something like this,

Newegg.com - StarTech 6.02" 6in TX3 Fan Power Splitter Cable Model TX3SPLITTER

Using a molex splitter (or adapter if the fans don't have molex connectoes) or a fan controller,

Newegg.com - Sunbeam RHK-BA Rheobus 5.25" Bay 4 Channel 20W Fan Controller Panel (Black)

would be a better option as there is no chance of possibly overloading the header on the motherboard and damaging either it or the motherboard.

I see. What i'm looking at is the CM 120mm fans. Is it ok? & what kind of fans that run off the PSU. Sorry, i don't know much abt hardware.

Thanks. The 1st link is the one i'm talking about. & is it compulsory to install the fan controller? Could i just use the cable splitter only?

From reading the user comments it looks like it can be used as just a splitter, with the motherboard connector only really needed if the header on the motherboard is a 4 pin PWM connector and the fans are PWM capable as well.

The controller is not mandatory.

Most fans use under 1 amp. Many under .5 amps. Unless you are using powerful fans, you can normally connect 3 to a single header by splitters.

Any fan will run off the PSU if you have a Molex connector for the fan, rather than the standard tiny 3 pin or 4 pin connection. Molex connectors go directly to the PSU, unlike 3 pin or 4 pin connectors, which go to the motherboard.

If you use Molex connectors, you don't have to wonder if you might be overloading the motherboard fan header.

Yeah you should be fine if your only running 120mm fans, its when you start running fans like this Thermaltake Case Fan

I see... So the recommended amp for each fan to be able to use a splitter must be 5 and below? Or any 120mm fan will do?
