hi guys and girls i'm in a bit of a pickle and need a bit of help

i have a 810 case with 4 fans at 12v (you know that thing at the back of the case where it has 7 fan in the 1 molex) and it's a bit loud is is there any way i can reduce the power to make it a bit quieter?

any help will be awesome!!!

It's not a fan controller, more like a HUB. If you want your fans to run at lower RPM's, you're going to have buy a reduction cable for each fan and put them between the fan and the HUB
 
ok cool i'll looking to that. anything you would recommend?
i was hoping that there was a 4 pin molex reducer...

After what i have seen and know, you can only get to the fans. So go after that, cant see the point on doing things to PSU mate ;)
 
The only manufacturers I know that make them are Nexus and Akasa. I know that when you buy Noctua fans you get them with the fan, but I'm not sure if they sell them seperately.

4 pin molex reducers don't exist, or at least not that I know of.

You could always try using the fan headers on your motherboard? You can use software like Speedfan to set the fan speeds :)
 
You can get 5v, 7v and 12v all off one molex by rearranging the cables. I don't see why you couldn't remove a couple of the cables, and rearrange the order of the remaining 2 to 5v or 7v.
Someone else may have more of an idea? But I'd have thought it would be do-able...
Unless for some reason the hub wired in all 4 of the connectors somehow...

If you could do that, you could just buy a molex extender and rewire it.

Otherwise, you could just leave the hub and buy a couple of:

It'll probably work out about the same price tbh. You'd just end up with a little more wiring.

There are also individual reducers available:

But to me it just seems stupid in getting resistors to reduce 12v to 7v when you already have a 7v power source from the molex anyway...

@Feronix - motherboard headers and fan controllers are banned :p
 
Motherboard headers look messy as you said, and can't even provide a full 12v (not that that matters)

And fan controllers are just stupid. Nobody needs to keep changing the speed of fans every time they do a demanding application. And it's just stupid to think that if you forget to put your fans up that your system is going to overheat... It just makes more sense to me to set your fans up at the noise levels you like them and leave them there, so your rig is quiet all the time. Then adjust your overclocks according to your cooling performance at the noise level that you can put up with. That way, after stress testing, you know that's the maximum temperature your system is ever going to hit...and it isn't going to overheat if you forget to up your fan controller.
Oh - and also fan controllers are messy, and half of them work by rapidly turning fans on and off which can actually make fans a lot louder and destroy their motors.

Just stick to voltage resistors or fan speed cables.
 
like above...
best thing to use would be a molex to 3pin adapter or molex extenion cable and get the pins out of the molex plug and put the 5v(red) where the 12v(yellow) was. then get rid of the 12v cable and a ground cable so you only got a black and a red cable going into the hub... that way you got 5v instead of 12v. for 7v the 12v cable stays and the 5v cable goes where the first ground was and get rid off the two ground cables.
hope you understand what i mean :)

I agree - your diagram doesn't make a lot of sense when you don't know which way up the connector is though...

Look at the bitfenix ones - that should give you a better idea:

ROFL ok, ok i get your point!

Don't use the roof for rads way to loud up there luckily the things a monster and you can place them just about anywhere else.
