Molex Battery?

[ChaseB]

So I have a NZXT fan controller. I have 4 blue led fans from corsair plugged into it. I was wondering if they make a device that when I turn off my computer, the fans still run for a period of time. I think it would be cool looking as well as to cool the devices inside. Anybody know if my fantasy exists?

You could wire it up with an Arduino or otherwise fairly easily.

 

Power in to the fan controller, and when reset switch closed, start timer. On power, reset board.

Not as simple as just flipping a switch, but fully auto!

I don't think so... 

 

I know the Enermax Revolution X't PSU has this where the fna continues spinning for a period of time after the PC turns off but unless you get really DIY I don't think there's an easy way to accomplish this for molex accessories/fans unless you know how to use Arduinos and stuff like that (I don't)

[Clear17Mud]

you dont need to have the fans still run after the pc shuts down because it isn't producing heat anymore. I know it looks cool, but  I dont think it exists

[Bussinateur]

Get an external supply that's always on and connect the fan hub to that. 

[Kyuubixchidori]

get a pico power supply, plug it into that, and leave that on 24/7?

This seems like a more elegant solution

But... where's the fun?

really you don't say well. I was just trying to help and now you created and enemy.

Calm down, guys. No need to get all upset.

[Clear17Mud]

sorry, I did calm down a lot from what I was going to say.... that just pressed my buttons all wrong

[Mujteba]

What op is asking for is a turbo timer for his pc.

This is true, you could try this http://www.instructables.com/id/Super-easy-battery-powerd-computer-fan/ and just have it wired in alongside your 3 pin connectors from your mobo.

 

Some things to think about;

A: Your going to have to wire it as separate switches from your mobo, so you won't have voltage going INTO your battery or mobo

B: Your going to need to flip a switch every time you shut off your pc.

C: Your batteries will die eventually  

 

Another possible idea is just using an nzxt grid+ hooked into all your fans (like you have) and run the controls from another pc!

This would look a lot better and be a lot easier to setup.

Some things to think about;

A: Your going to need a second pc, preferably connected to the internet so you can control it with your phone on the CAM app, this could be space consuming and the CAM software only runs on windows :\ so no tiny raspberry pi business

B: Your fans won't run in response to your systems requirements, as they would respond to the system its hooked up to's. (Your CPU gets to 70 and your fans won't turn up, etc.)

 

Other than that theres not many practical ways to do this atm :\

My solution isn't quite as complicated. You could actually wire up a 555 IC timer onto a PCB internally, using the already-integrated switches. Technically, you wouldn't even need arduino/pi.

I didn't realize he just had the nzxt grid vs the grid+, which just runs off of molex without the CAM software.

 

The problem is though, your power supply stops giving power after you shut your pc off. 

He'd have to run a battery line or have a completely separate power supply.. you couldn't just wire up a timer for what he's wanting.

The IC chip could theoretically branch the power out to keep it on until the timer is up, then the timer opens the connection, and shuts off the PSU.

I am not using a grid I am using a sentry 2 that goes in bay cover.

...without wiring to your psu I'm not sure how thats possible...Just saying...can you explain in further detail how that would work?

Gotcha, same premise, runs off molex.

Just get this to be honest, http://www.newegg.com/Product/Product.aspx?Item=N82E16812123309

Just turn your fans off when you want to

Branch right off the 24-pin cable.

Your still sending power to your entire system that would take a lot of wiring to have that timer run shutoff too, and you'd need an arduino at that point

I'm just saying branch off of it directly. It'd be some wiring, but you could do it without any boards.

 

Like, Potentiometer to control timer, timer controlling a switch on said 24-pin to hold off power (with a relay), bridged pins to keep power running up to the switch, timer ALSO shutting fan power off after time.

 

It'd be a little while, and certainly not as easy as an external brick, but it'd be an interesting mod.

Ahh that could be done then, only thing id worry about is resistance from the PSU when the pc gets power hungry, but it would probably be fine

Might be a cool project at some point though..

 

AND HOLY CRAP YOU LIVE IN FW?? I live about 10 min north of Auburn!

Oh cheers. I was up in Angola yesterday for work.

ok so I am running a Sentry Mix 2, what Mulex to Ac could power it.

No way, where do you work if you don't mind me asking? I was there yesterday too

The one I linked earlier should work fine
