help with fan speed control

hi,

can anyone tell me if this will work to control fan speed...

the fan.... a 12 volt, 4inch inline fan

a fan speed controller of ebay, its a plug in one and ....here is a pic...

sounds plug in and your of..

but would it make a difference since its not 240v fan im trying to controll,,,its a 12v, so i guess ill plug my big black adapter into the control unit, then plug it in the wall ?

thank you for any help

well if that controller plugs into your outlet and your fan , and it says 12 volts on it and you plug it into 220 how would the switch know the difference right, but from my experience I buy the correct stuff I would be afaried some thing bad would happen using that, it prob will work , I would not use it, its up to you mabe plug it in watch it run for a few make sure it don't get hot

thanks for the quick reply, mmm,,am the same, i think ill take a rain check on that one...ive seen another fan on sale on ebay but it doesnt say the voltage, just that a plug will need fitting, so am guessing standard....so in all, thats should work,,,? am i right in saying that a speed controller is nessersery? im all on one about the smell when flowering....whats ona gel...????

Do you mean 120 V? 12V is generally DC, not household AC
