[SOLVED] How does this molex PWM fan splitter work?

[FrankClinton_XPV]

Hey guys I found this fan splitter , and I have some questions about it.

What will happen If I connect 6 PWM fans via this adapter? Do all fans run at same speed because they get same PWM signal?
If one fan's speed increases due to heat, speed of all other connected fans will also increase similarly? I mean will all run at same RPM?

My mobo is Gigabyte H81M-S2PV Rev 3.0.
This gets additional power from one molex connector, so do I need to worry about frying mobo's 4 pin PWM fan header?

Any help is appreciated......

in order asked
1 see number 2
2 yes
3 presumably, the splitter must share all signals across all connected fans.
4 yes. the PWM from the motherboard will be duplicated to all connected fans
5 no. the molex will supply the extra power for the extra fans, the molex can carry the amperage needed, the motherboard header has enough power for maybe two maximum fans per port, the speeds will decrease as the load increases on a fan header.

Thanks.....

the speeds will decrease as the load increases on a fan header.

with or without this adapter?

without. system has DC power and like a battery that has too many bulbs connected each bulb will dim more as more bulbs are added.

with the setup (adapter and connected fans) are powered by the power supply (which in the analogy is a much bigger battery)
