[SOLVED] how do i controle 4 fans with 1 motherboard PWM

[ikRick]

i nede help, i have 4 fans but with the stock connector the fans will always be at 100 percent, what kind of splitter do i need? i already have a splitter but thats not working.

You would need a PWM fan splitter.

Something like these....

Fan Splitter

Fan Splitters

You'd need a powered fan hub. A splitter is going to be problematic as most ports can only power 2 maybe 3 fans. With a powered hub you can run multiple fans from 1 port and it gets it power from a sata power connection which can easily power multiple fans and the fan speed is controlled by the motherboards pwm port.

To get the right answer, you need to tell us more details.

1. What maker and exact model mobo?
2. Assuming all 4 of these fans are the same, tell us maker and model number. If you don't know, here are the two key items we need from them:

(a) How many wires from the fan? 3, ending in a connector with 3 holes, or 4, and a 4-hole connector?
(b) On the fan label, what does it say for Amps (A) or Watts (W)?

Background: 3-pin and 4-pin fans required different types of signals from the mobo header to control them. And this impacts exactly how you can connect several to a header. So fan details and the mobo header capability are required to get he right solution.

A PWM fan hub will do the trick, I bought the Phanteks one, sata powered, everything worked a treat.

That new Phanteks Hub is the most capable on the market right now, but you may be able to do what you want with less complexity and cost, OP, if we get those bits of info I asked.
