Fan control idea

No none turn them off, they just turn down low enough for there to be insufficient current to start the fan spinning. That's not off. If you have led fans the leds still glow.

Untill someone has the FC8 or there is a review it could be the same.

I'd prefer a seperate switch anyway so the speed can be set and left there while still being able to turn On/Off.

I have a Scythe KM Ace and an FC5 controlling LED fans and it turns them off including the LEDs. The FC8 CLEARLY says the voltage range is 0-12v so yes this too would be OFF.
 
I have an Akasa AK-FC-03 and it doesn't turn the fans off. The FC8 spec can say what it likes, untill it's reviewed or someone has one you can't know for sure.

None turn off, as in 0 current.
 
yes they turn to such a negligable voltage its not worth worrying about.. 0.0-0.5 v isnt going to spin any fan or light a set of 4 leds up...
 
Anyone know where i can get a bike for my goldfish?

If you want to follow this dream then get 8 SPST switches, split the live lines on each fan extension, dont worry about grounding as the switch internals are isolated. Leave the tach lines and grounds intact.

Post pics of the finished mod. If you like you could get a bay bus with the switches and faceplate already done.

Edit = Just checked my FC5 and the voltage when "off" is 0.02 - 0.07 which is so negligable and within the realms of multimeter error. I would assume the FC8 is much the same ;)
 
You can use multiple pole switches, diodes, wire and solder to make fan control switches. A diode drops around 0.7v just by being in a circuit so if you can find a switch with enough poles and know how to wire it up you could have a nice solution. You could leave one if the switch posts open for zero current.

Multiple pole switches can carry a fair bit if current so could control multiple fans. Several could be mounted on a drive bay.

Thought about this idea myself but never bothered to actually do it.

Yes I've got one here, I'll swap you for a controller that meats my requirements. :D

The point is you said all controllers turn of, they don't. Some very nearly do some don't at all.

None meet my requirements. So yes I will contine, it's not a dream, it's happening. I'm confident I'll be 100% satisfied with the results too.

Multimeter error deosn't count when measuring yes or no. You could assume the FC2 is the same as you FC5, but it's not.

If your going to continue being an asshat I'll politely ask you go do it somewhere alse.

That's what this does although a simpler version with less control. Combinig switches and a controller provides the best of both worlds.
 
For what most people want, a fan controller turns the fans OFF... How many rigs do you see with a set of fan controllers and then switches for said fan controller. 0.05 volts is SOOO negligable that you could just say its OFF. Out of the 5 or 6 controllers ive had, none of them have failed to switch the fans off. You seem to be misguided.
 
Maybe I'm too dim at the moment to get what you need.

Do you want the switch just to isolate the current going to the fan completely, irrespective of the position of the dial on the fan controller?

Surely just breaking the red wire on the fan's lead and running it up to a on/off switch and another back down would be enough for that?

Running a wire from the incoming molex up to a switch would isolate the whole controller if that's what you want.

I don't relish the idea of running a computer with no fans running but each to their own I suppose.

Not dim at all, that's exactly what I want and what I am doing, switches are ordered.

I won't be turning them all off, 2 or 3 will be on all the time I'm guessing. Who knows though maybe it will run cool enough at times to be able to turn them all off.
 
Good stuff. Please post pics of your fan control mod when you have done it! :)


Here's my front panel switch mod. One switch is used to turn on and off my LED array of 2 custom strips and 2 custom modded LED fans. One other is used to turn on and off the panel LEDs.

For someone with my crafting skills and tools I thought this was a decent result. The switches were originally White LEDs.

That's a lot prettier than my effort Teal'c, nicely done.

^Yep, it seems that I've put together a diy version of that off the shelf thing. It does work well, seriously worth considering as an alternative to continuously variable voltage.

Multipole switch with diodes joining the pins is a clever solution, I like that. Beyond my skills to solder though I fear.
 
I didn't take too many shots of the process as it wasn't going to be an instructional.

Initially I was going to just mount the switches in a drilled and filed strip of 2mm steel I cut out of an old blue lockable box we'd had in the cupboard since 1994. Unfortunately the drill caused the material to bend and buckle.

Here's a close up where you can see the two holes I drilled and two LEDs fitted. I had to trim away the material of the drive bay cover to accomodate the LED legs.

I experimented shining a LED through in different ways and decided that 3mm holes drilled in the corners allowed the light to shine through the material and collect at the edges. I did consider two or four extra LEDs in the centre section but decided that it might be too much.

One small problem I did have was that the Acrylic I was using was 3mm and it needed a 3mm hole to hold the LED. I offset the hole slightly towards the backside.

I glued one or two of the LEDs in place with a tiny blob of hot glue so that they didn't fall out all the time and this made a tiny bit of mess.

I did buy another piece of Acrylic in 6mm (I think) to have another go, that was several months ago and still I haven't done anything. I suppose the first attempt was adequate enough for me.
