Are 4-way fan splitters available?

What if I wanted to have 4 fans all run through the CPU fan connection and be controllable.

It depends on your fans if they are 4 pin PWM you can get splitter hubs such as thees:

For 3 pin fans you will need to double check the current draw of all the fans to ensure it doesn't exceed the header's rating, usually it's 1Amp.

They're 3 pin so that Silverstone unit will not work. You will want to keep it below the 1Amp rating ideally never past the 0.75Amp amount for proper safety margin.

Does using more fans in the splitter cause it to distribute less power to each?  

 

So i look for a 0.75 splitter?

No it doesn't work like that it uses the same voltage but increases your load or amperage on your header hence the 1 Amp max rating. Looking at the specs it's only around 0.09Amp per fan (0.36Amp Total), at startup it will be more than that but even so 4 Pure Wings 2 fans shouldn't be an issue.

There are 4pin pwm PW2's. https://www.bequiet.com/en/casefans/617

Oh there are two models, @minervx which type do you have?

[minervx]

3 pin.  140mm

In that case for 4 fans it will draw a total of (0.48Amps).

is that bad?

 

i want the fans to spin slow

No, that's not bad. He's just explaining how much power the fans will draw. Most fan headers will support up to 1A which is plenty for a theoretical power draw of 0.48A.

Fan control will depend on the header you plug the fans into. What motherboard do you have?

asrock ab350m pro4 (matx)

 

non-pwm fans.

 

it has cpufan, 1 controllable chassis fan and 1 noncontrollable chassis fan. 

 

i want 5 fans in the cpufan connection and then set my bios to a silent mode profile

Are you sure that the other cha_fan header doesn't provide any control? Looking at the user's manual, I don't see anything that would indicate a lack of control options.

If you're going to plug the fan into the cpu_fan header, make sure that the header is set to DC mode if the option is available in the bios.
