Too many fans, not enough slots

[Bogdan_77]

I have 6 case fans and 1 cpu fans (all pwm) and i only have one cpu fan header and 2 case fan headers on my mobo. I dont have any drive bays on my case to insert a fan controller so how can I control all these fans, they are 3 intake and 3 exhaust.

Solution A: get a fan controller. They're about 40 bucks.

Solution B: get splitters,connect 2 fans per header and connect 2 fans to the PSU -- downside those can't be controlled and will run on 12V (or 7/5V with adapters)

a: i dont have any room to place a fan controller, my case doesnt have drive bays

b: is there any way to control all of them, do three way splitters exist?

They do but can cause problems. Check you main board specs on how much power they allow to output over the header.
Also there are fan hubs that can be placed inside the case. However I'm not sure if they can be configured or just output full speed.

Also there's an external fan controller by NZXT that gets connected via usb2

yeah i've been doing a lot of research and i stumbled upon these http://www.akasa.com.tw/update.php?tpl=product/product.detail.tpl&no=181&type=Cables&type_sub=Fan%20Cable%20Adapters&model=AK-CBFA06-30 its a powered 3 way splitter. Would this work? and if it does is it okay to have 2 fans of the same kind and one different one on the same splitter?(2 140mm and 1 120mm)

I originally wanted to get the NZXT controller but i cant find it available anywhere for the time being/a reasonable price but that wouldve been ideal

You have to look in your main board manual how much power the.board can output over the fan.header. if 3 fans consume more power than the header is designed for you'll run into trouble
Check your board manual

The splitter in the link has a sata connection for the psu, do i still need to check the header in that case?

Sry link didn't open earlier today.
You can connect it directly to your PSU. You might not even need a splitter if there are enough connectors on your PSU.
The big downside is that the energy output is not regulated. So all fans connected to the PSU will run with 100% rpm all the time

So the fact that it plugs into both the psu and the motherboard doesnt mean anything? Will it just run full power the entire time?

It doesn't . matter if it Plugs into a SATA controller as the main board will not recognise it as a fan and it will draw max power.
Fan control on the main board only works when connecting to the fan header.

it has a connection for a fan header

Oh...well this could work in theory although I'm not entirely sure.
Are those 3 Pin or 4 Pin? PWR could work. Not sure about non-pwr though. Never seen a design like that before tbh

Your case doesn't have any drive bays?! Wow, that's a first.

You can get fan controllers that occupy a rear slot, such as this one.
