Daisy chaining fans

[RedLithos]

In my setup I have an Arctic 120mm case fan plugged into my CPU fan header. The CPU fan is then plugged into the extension branch of the case fan. Does this slow down my CPU fan or am I fine?

Do you mean you have a splitter on the case (SYS/Chassis) fan header and 2 fans plugged or the CPU fan plugged directly to a case (SYS/Chassis) fan header?

I have my cpu fans separate from the case fans. The case fans are daisy chain together and goes to a separate fan header on the board.

afaik, daisy chaining is a series connection, what I think you are describing is a parallel connection (correct me if I'm wrong) so it will have an effect on the current delivered to the fans meaning a drop in fan speed for each fan at a set voltage.

The case fan plug, which is connected to the CPU fan header, branches off into: a) the fan itself, b) a header for daisy-chaining. So my CPU fan is plugged into the header branch.

Daisy chaining is just a general term for having stuff powerd in a strip type fashion. Like Christmas lights are a daisy chain and so are the sata power connectors that go down from one line.

Still a parallel connection, there'll be a drop in your CPU fan speeds, unless you increase the voltage supplied.

Christmas lights are wired up in series...so we mean the same thing.

Are half a set in series then both haves are parallel.

Sorry for the stupid format, I'm on mobile
