[SOLVED] Fan Splitter Cables dilemmas

Hello!

The Motherboard has 2 x Chassis Fan Connectors (1 x 3-pin, 1 x 4-pin). The Chassis Fan Connector supports the chassis fan of maximum 1A (12W) fan power.

1. Is it safe to use Fan Splitter Cables to plug in several chassis fans on the same Chassis Fan Connector? It wont make any damage to the Motherboard or the PSU?

If the answer is yes:
2. Will all fans connected on the same connector work with their fulls speed, or their speed will be decreased because they share the same connector and the same power?

3. Is there a limit on how many fans you can connect on the same fan connector?

Thank you!
 
1. Yes it's safe as long as the total draw doesn't exceed what the motherboard can put out safely....which in your case is 1 amp.

2. They will all run at full speed.

3. The total draw shouldn't exceed the rating (in your case 1 amp).

add up the draw of the fans.....the total has to be less than 1 amp.

Thanks for your fast reply!

So, for example if I take this fan where it says:
12cm 12V 1A 4-Wire PWM Silent Large air Volume Chassis Cooling Fan

Does it mean I cannot use 2 fans like this one, connected on the same connector because each of them is 1A, so both of them will be 2A?

I need to look for 2 fans with specs 12V 0.5A ?

True....but I'm a little surprised your fan is 1 amp.
I'm used to case fans being a fraction of an amp.
For instance.....these case fans are .16 amps so you could use 6 of them on one header that is rated for 1 amp.

I just took this random fan in the example:

I think that might be a large fan....plus it's 24 volts..
If you look at normal 12V case fans I think you will find they are generally around .10-.40 amps or so.
