Hey guys, I just bought 3 new PC Fans and a couple of DC adapters, problem is, the pc fans run at 12V and .6A and the adapters I found output 12V and 1A. Am I going to burn out the fans pretty fast or should they be fine? Thanks for any input you guys have in advance.

As long as you use the correct voltage,12v, the fans wil operate properly as long as your power supply is rated high enough to supply the current your fans need. so add up the amp rating of all your fans, this total is what your power supply will need to be minimum, rated for more amps its ok, just gives you room to ad more to it. but if your supply is rated at a lower amperage than what all your fans are gonna draw, youll more than likely burn up the power supply

So you have 2 adapters rated at 1 amp each, so your total available current is 2 amps. you have 3 fans rated at .6 amps each, 1.8 amps total. SDo you do have have enough available, but with only 2 adapters, you need to either buy another adapter for the third fan, or you could wire the adapters in parallel and run all 3 fans off the 2 adapters. More simply, Maybe get 1 adapter rated for enough amps to run all ytour 12v equip.

is it possible to run all fans off one adapter splice the wiring that will reduce the amp going to each fan i would think.

I run a PC power supply. You can get them pretty cheap about $10-15. This will also give you several lines as well as a much higher amperage availability. So if 3 fans aren't enough you can add more.

actually, it will have quite the opposite effect...
every fan pulls amperage, a fixed value of amperage per fan. say each fan pulls .5 amps. so wire 2 fans together and you have 1 amp... wire 10 fans together you have 5 amps, and so on and so on.... you dont 'reduce' amperage by adding devices that consume power!! :wall: :lol:

good post- you forgot a CRITICAL step however-
when using multiple power supplies YOU MUST CONNECT THE COMMON (negative) outputs together on ALL the power supllies of same voltage... so if you have 10 wall adapters, you best have the negative wires connected together on all 10 power supplies, lest you are playing with a very real danger called opposite potential between seperatly derived power sources. in other words, firetrap if you dont do it. most people are not even remotely aware of this!
there is an entire section of the National Electrical Code devoted to this topic....

An easy way to solve this is to either find a scrap pc power supply or buy a new one of cheapest and lowest wattage u can find, google which 2 pins on the ATX contact u need to connect together to jumpstart it without a motherboard and there u go =).. it can handle as many fans as u want and it will allways be delivering correct power to your fans. Allso even if it says its 250w it won't suck out 250w, its just the max it can handle..it will only use enough to pull its own weight, meaning the internal fan, itself and the fans u hook it up to.

Or just run with the stuff u got, should work fine as well. I went with the pc power supply since i allrdy experimented with making home made table fans glueing together like 9x120cm into a wall of fans for lan partys in my early teen years before i started growing.

Most ppl here got a pretty decent vocabulary. I'd love to get rith of what u'd call a typical foreign accent even tho we dont sound like arabs ^^ Everyone here learns English from 2 grade until they graduate and we are heavily influenced by english through music and commercials etc. I guess its just a question of decades until it becomes like a alternative everyday languish other then the allrdy existing wordplay with slang and ghetto lingo..

Just realised this would fit better in toke'n'talk so i'll call it a day from here ^^

Edit: we might not have legal pot yet but at least we got snus ^^
