Topic 7 volt Fan Mod - Anyone tried this?

wifiry

Hi All,

I'm using a generic system fan which is pretty loud! I was just wondering if anyone had tried the 7 Volt Fan mod? Apparently it can really quieten then fans to save paying over the odds for silent ones. Search Google for 7volt Fan Mod, there are loads of references to it. Let me know if you've tried this.

Cheers

I've tested it a while ago on my old computer and it works fine.
The fan speed and noise gets reduced.

But it can be a bit tricky to remove the wires from the connector, so it can be a good idea to have a spare or two since you may break it when you remove/connect the wires (depending on the connector type)

Found a quick guide here by the way:

But I haven't needed to mod the fans the last couple of years since silent running case fans are really cheap now anyway.

Yeah I noticed last night that the PC I have running my entertainment systems is a weeee bit noisy in the fan department...I'm probably going to look into replacing all the fans with silent running fans...

But why bother taking the fan apart just get some mating connectors and a resistor and make a pass through...You are already putting losses in with the resistor so any other losses with the connectors are, well who cares...plus it is only a fan so connection losses, are well who cares...

I think I'll give it a try on my next days off, I'll let you know.

I always go with larger fans. They run at a lower RPM and put out more air. The larger the fan the less noise trail it is going to produce because their sound is at a lower octave. You get the "hummmmm" sound instead of the "wizzzz".

I've just ordered two 80mm Nexus Real Silent case fans.
They've got very good reviews, and it says that they shouldn't produce anymore than 17.6 dB(A) and that shouldn't be bad at all.

A fan control would help, slowing your fans when not working your machine would make it much more quite....
