computer fan question
    #848383 - 08/28/02 03:43 AM (22 years, 5 months ago)

hello.
i wanna use a computer fan in my growing chamber.
on the fan there stands "12V 0,08A".
but i can't find any tranasformator with 0,08A...
what would happen if i run this thing with 0,4A for example?
would it break down?
is there any way to lower the Ampere-number?

if the fan is 8 mA and the transformer is 4 mA the result will be...

to BURN the transformer, because the fan will "pull" double the power the transformer can produce.

i use a computer fan for my grow chamber. I took an old AT style power supply and I'm using that along with a digital timer to automate my "fanning". I've also setup an array of 480nm LEDs tied into the 100mA/5V output available on most power supplies.

@ kykeon
thanks for your answer
i'm not really good in these electronic things, but i think 1 mA is 0,001 A, right?
then i need 80 mA...

so the transformator must have at least the power the fan needs, right?
what would happen if i use a 0,1 Ampere or a 1 Ampere transformator?

Lemme get this straight...
you can't find a "transformer" with an 0.08A output...
your biggest problem is that a transformer only increases or decreases amperes for AC. Your "computer fan" runs off DC. instead of worrying about having to increase/decrease amperage and then converting to DC, just use my previous example of an old computer power supply. It already converts AC to DC, and the fan is designed to operate using the power supply's outputs. you want an "AT" style and can prolly find one on E-Bay for a couple $.

transformators cost more than computer fans. so if you do have a transformator, take it with you and go to a electric/electronic shop which sells those kinds of things and ask for a fan that complies with it. its simple.

if you do have a computer fan, then a computer transformer must be perfect [check it out first].

btw, i have seen some NEW ROUND computer fans sold in my neighboorhood, in a computer shop and they were sooooo cool!!!

@ fosphor
> Lemme get this straight...
thats what i want

i don't know if i really agree with you...
a transformator is connected to an outlet (which has AC power, right?) and converts it to DC. i don't know what type of transformators you think of, but mine do this...
i don't want to use a computer power supply. it's to expensive on ebay (price only some Euro, but the transport is about 6 Euro) and transformators you'll get at ebay for 1 Euro... (ebay.de)
my only question is, can i use a transformator, which gives you DC12V and 1,25A for example to run my DC12V and 0,08A fan... someone please say yes or no...

@ kykeon
thanks, i have the fan and i only don't want to buy a transformator, even if it only costs a few bucks, if i can't run it with the fan...

My hairless cat went through the hassle of trying to use an old DC fan with an old computer power supply. Too bulky and it eventually sparked up and died on him. He found an AC fan of the same size/power online for 12.00, spliced it into a normal plug and he runs that on a digital timer for his ventilation. Works great and you just have to figure out the right intervals to maintain your humidity. Plus it's a hell of a lot less bulky than a CPU power supply.

uh! i forgot to write that if you plan using a fan for your terrarium, TAKE CARE!

Your shrooms will be white... thats why my equadors were born white. You have to make a shield to protect them from direct air current. Its important! Air movement make them 'crack' their caps and eventually lose their color...
