Get a fan splitter?

but isnt that too much voltage? i have the corsair ll series 140mm the rgb

fan splitter: A cable with two headers on its two ends, like a two headed snake. Make sure you check the maximum current draw of the header in the motherboard manual to make sure the fans dont overload it.

 

fan controller: this looks more like a USB hub, but with fan headers instead. These can handle a lot more fans and also need a molex connector to supply power.

voltage stays the same, it's the current that can change.

1A maximum for each header on the motherboard. Add up the case fan's current rating.

You could try plugging your fan headers (which I'm assuming which are 3pin) directly to your Power supply via a 3pin to 4pin adapter. I have done this with 3 of my fans for a year now and I haven't ran into any problems. I am using a Thermaltake Litepower 750W PSU

they are not 3 pins they are 4 pins and no i dont like this way thank you!

there should be a label at the back of the fan.

it says rate current 0.30 is that good or bad?

yeah, you can connect at most 3 of these fans to each header on the motherboard.

like my motherboard right now has 2 case fan headers only. i connected  2 140mm fan i still have 1. should i buy a splitter and connect it? is the current rate fine can it handle it? i didnt understand what you mean?

I have an itx board with 2 splitters...you're over worrying about it.

with a fan splitter?

[skillz]

I have 3 fans on one 3way splitter from this mobo, works great, as it does not exceed 1A in total!

how im gonna know if its gonna exceed 1A that what i cant understand ? like it says current rate as u can see is 0.30 and rgb current is 0.65 so lets say 2 fans from those on one splitter with the 0.65 rgb current is 0.30 its like more than 1A am i fucking missing something here?

[skillz]

The RGB connects to another header, yes?

I dont know about corsair fans but i assume you have one fan header and one for the RGB separately, if that is the case, then they only draw 0.3A which means you can run 3 of those fans from 1 header

0.65A is RGB current. You don't need to worry about that, they are powered and controlled separately. You are looking at fans current, which is 0.3A. Most of fan headers are 1A per. Meaning that you can safely connect 3x0.3A fans, equaling 0.3A in total. Some headers are marked for high power. You can check from mobos manual or product page if there is such. They are either 2A or 5A per. Meaning even more fans.

 

You can go ahead and get 3-way splitters. Or just Y-splitters. Remember that splitter has one master and others are slave. Which means that one fan dictates what speed all connected fans are running. Usually this doesn't matter as you want to connect fans in same region or same type to single header/splitter. But if you are mixing fans, remember to connect the one running at highest rpm to master slot so you don't get any surprises with its speed being so much higher.

Correction, 3x0.3A totals 0.9A

i ordered 2 way fan splitter. so if i connect the 2 fans to this splitter from that 1 header? ill get different speeds?

Only if fans are different model and their max speeds are different. If they are same model then speed will be same. With margin of error.

they are the same fans the same series and same size 

[skillz]

Then they will run at same speeds
