Molex Alternative?
 

I have 7 case fans in my chassis and those Molex to 3 Pin adapters are starting to pile up and are really messy. Would there be any available options? Such as a PSU with a bunch of 3 Pin connectors? or Fans with a stright up Molex or Sata connection even? or am I just nuts?

My homemade fan splitter - one cable in, nine out :biggrin:

I've got one of these in red. 11 fan headers, but 4 are 12v, 4 are 7v, and 3 are 5v. Good for undervolting those 3000 rpm fans, not so good if you plug your pump into a 5v like I did on the weekend.

What kind of voltage distribution do you get on that?

Parallel distribution - every output voltage is identical to the input voltage. Obviously, I have to pay attention to the total current draw, but the PCB itself is fine up to around 3-4 amps, and probably just as high as 5-6 amps total. And I'm getting power right off the PSU, so there's no danger of overloading a motherboard header. The rpm sensing is also useless - I only soldered those on to make the pin headers more solid.

Agreed, but don't all those signals get bunged up? I guess not if that's what you say...:haha:. That is a great PCB you have there and now I'm thinking of getting one.

There shouldn't be any problem - at least I'm pretty sure. To the best of my understanding, fan rpm signals are just Hall-effect pulses, so they shouldn't strong enough to affect each other.

Or did you mean "bunched up"? Because there's no (reasonable) way to sync the pulses up between fans, so any sensor on that line would be getting a whole shower of pulses at weird intervals. Nine fans at 1000rpm might give out a reading of 1000rpm, or they might give a reading of 9000rpm. :biggrin: And you'll never see 0rpm unless all nine fail, so it's not even any good for a fan failure check.
