Default Adding more case fans

Hi all,

I recently got a new case and it has got 4 or 5 (i think) fans. However my motherboard only has 3 system fan heads. Im not sure what the adaptor is called, but is there something that will allow me to grab power from the PSU or share the power coming out of the fan header from the mobo?

Also if I share the power coming out of the fan header, will the speed of the fan(s) connected to the header be notably slower, thus have less air flow?

it depends on the fans themselves.

what case did you buy?

molex - 3/4 pin adapter is usually what you are chasing.

fans run directly off molex will generally run full speed unless connected to 5V so some sort of fan controller is usually a better way to go.

couple options you have

something like this

https://www.scorptec.com.au/product/...3162-SST-CPF01

just a standard cable, allowing you to plug 2 fans into the one header on the mobo.

or you can go something like this

https://www.scorptec.com.au/product/...81-AC-GRDP2-M1

Allows you to control the fans via software in windows.

From memory, most motherboards allow about 1amp of power draw.

This is plenty.

If all your fans are the same run them with a splitter from the motherboard, as long as the current draw is less than one. If it is more use a spliter with a molex. That way the motherboard controls the fan speed, yet power is directly from the psu.

This link should show everything you need.

as power said i would recommend a fan controller if you don't want to use fan spliters that run off the motherboard headers.

I have until my last build never used a fan controller but i dont think i will use anything else now.
I went a bit overboard and got the corsair commander mini. considering everything else i have is corsair (H100i and AX1200i) it all shows up in corsair link and i can set everything in one place.

the commanders are great. i didnt link that one since its twice the price as teh nzxt

having used both, the commander is better then the grid.

Hahahaha seems like alot. Can never have too many!

If I remember correctly, they are positioned:

  • 1 x side panel (blowing at CPU and GPU)
  • 1 x rear
  • 2 x front for HDDs

Well it just takes extra power that isn't necessary.

Checked the sys temps with 2 less fans and see what you find ; )
