[Resolved]Quieting a 4 Pin laptop fan.

post #1 of 6
Thread Starter 
So here's an odd request / question for you air cooling guru's out there.

I have a spare Dell e6410 laptop fan that I'd like to.. test with.

The fan is somewhat loud, even when idling it's audible. All whilst my temps are well within check. That led me to think, if there was a way to slow teh fan down, then my problems would be solved!

SpeedFan failed, since it's.. well a laptop and Dell isn't exactly #1 on the modder friendly side. It simply couldn't read the fan, fine whatever.

So here's the fan in question:


So, my exact question would be, is there simply a wire I can cut so it receives less power? If so, which one? Granted this can only be done once since this is my only spare fan, and I dare not try this on my last fan

Or is there another option?

FWIW, the bearing isn't shot and it isn't dirty, both fans make the same noise, even the Dell rep which seemed to know his stuff said it makes noise.. it's just the way it is.

Thanks

Well, you can't cut a wire to slow the fan down. Doesn't work that way.

You can use something like this,

Or if you are handy with wire do it yourselves.

Try i8kfanGUI which is a free utility for fan control of Dell laptops. It is a little outdated but there is no hard to try. It supports up to Vista and if it does not work for Win 7 (if you use that), try the compatibility mode.

If you wish to use the 'voltage reduction' cable suggested above, make sure the 4-pin connector is of the proper size. Usually this kind of cable is meant for desktop. For a laptop, the connector size is often smaller and then you will have to find another converter cable.

Maybe replace the fan. Same dimensions but different spec? Kind of a long shotvlooking for one though.
For a more reckless approach, remove grills on the laptop housing. It could be that giving air movement noise.

You can purchase that resistor connector, or you can splice in a resistor in yourself.

Thanks for the responses guys. Instead of quoting I'll just hit each one of you guys with a quick snippet

@trumpet: Good idea, that never crossed my mind, but one that connector is too big and two there really isn't much room at all to even try this :\\

@windfire: Another good idea, tried it, had to disable driver signatures and play with a few things to try to get it working, but I bluescreened out. Seems it and Win 7 with SP1 don't play nice.

@CrUk: I've spent countless hours looking, they all conform to Dell's speed / rotation specs so the noise will be there

@rawfuls: same as what was said for trumpet applies here, there no room really.. and to be quite honest, I'm not great with tiny wires like these

Thanks for the help guys, I'll just stick with what I've got and deal with it [insert dealwithit.jpg here]. Reps all round
