moddoing a computer fan so it reaches higher speeds
64 replies, posted
is there any way of modding a fan so it would spin faster?
increasing voltage would help, but I cant do that on a normal powersupply
so is there any way of increasing the current that it draws from the powersupply?
I'm doing this because I have a drawer full of 8cm fans which I wanna use for experimenting
No, you might be able to lubricate it better, but afaik there's no way to just make it spin faster unless you're putting more voltage into it.
You'll gonna have to install some turbo, engine upgrades and some Nos.
Oh yeah, don't forget to get some spoilers too.

You forgot LED's
Those make it go faster but only red ones
You could just buy one of those fans that spins so fast it hovers if you put it on a table.

But you need some blue ones too, so it won't overheat when you push it too hard with the NOS.
and with all that power being used, some green fans are a necessity.
Don't forget to buy bodykit either, it will modify the fan blades so it moves more air so you get all out of your mods!
Don't listen to these fools!
You need [b]BLUE[/b] led's so you can run cooler.
THEN you can Xtreme overclock the fans to max potential!
You might be able to make them go faster, but you'd need to take them appart and re-solder some stuff
Plus, it would only work on some types of fans
I remember it being possible on stepper fans
Hook it up to a car battery.
Because of the low drain, one car battery can power like 10 fans for ages.
We're talking years and years of non-stop fanning action.

Throw in a green one too so it's Alienware. Then it'll be more powerful just because.

I thought the green ones made your PC more energy efficient?
No, the green ones are alien tech so they got blue and red's advantages, cooling AND faster.

yeah I was thinking that
what would I have to resolder, if you know?

If it's plugged into the motherboard, get rid of the yellow cable, it will run at full pelt constantly.
If it's a Molex fan currently connected on the 5v cable, switch it around with the 12v
It'll make a lot of noise and the fan probably won't survive more than a few days.
Needs a jet engine
The only way to make it go faster is to overvolt it, and the easiest way to do that in a PC requires some explaination.
If I hook up the negative wire on a fan to 0 volts or Ground and the positive to +12 volts, i get a difference in potential by 12 volts (from 0 to 12) which essentially just means i'm giving it 12 volts. What you need to understand is that I could just as well hook up the negative wire to +5 volts with the positive on +12, I would then get a difference in potential of 7 volts (12-5=7) meaning I would essentially be supplying the fan with 7 volts.
Because there are no ATX leads in a pc with a voltage over 12 volts, you have to use the -12v wire on the 24-pin mobo ATX connector, which is blue.
(refer to [url]http://en.wikipedia.org/wiki/Atx#Power_supply[/url])
What you need to do is cut off and splice the blue cable, solder on the negative lead on the fan to it, then do the same on an Orange wire, which is +3.3 volts with the positive lead on the fan. This will result in a difference in potential by 15.3 volts, and if the fan doesn't fry immediately I can guarantee it will spill faster.

Just a word of warning regarding lubrication. Don't use petrolium based lubricants, they'll just heat up and grind into carbon, seizing up the fan and destroying it.
I'll give that a try, but I think it wont be needed
I found a powersupply in my garage and it's capable of controlling the voltage from 5-24 volts
lets just hope that the fans can handle twice the voltage

They can't. It's extremely dangerous to go beyond 12 volts.
I've fried a fan by accident with roughly 17 volts. But by all means, go nuts and experiment.
I ran some fans at 15V. They aren't supposed to melt, right?
The funny thing is that your thread icon is perfect.
just add some ice with red led
If you want it to go [I]really[/I] fast:

Put a bunch of them in a row, the first will 2x spin the second which will 3x spin the third which will 4x spin the fourth and so on
theoretically you could make the last one go millions of miles per hour!

Joking aside, chaining fans just increases the static pressure, not airspeed.
You can't just chain a bunch of fans and make your own high speed wind tunnel, the blades are still spinning at the same speed with 10 fans as it is with 1.
Yes that's true
I tried to do that once with 6 fans and was confused why the airflow was roughly the same
