Soldering Exhaust Fan / Laptop Cooling fan

I was browsing through instructables the other day and found several projects which I wanted to try. But before I did I wanted to make a exhaust fan to keep solder fumes out of my breathing area.Thus the three fan array.

For this project you will need:

3 12v fans
Nylon Sleeving
2" of 1/4" Heat Shrink Tubing
1.5" of 1/2" Heat Shrink Tubing
1  2.5mm power jack
1  12v power supply

For the powersupply checkout goodwill you can usually pick one up anywhere between $0.49 to $1.99
Whenselecting your powersupply you should select one that can handle the current needed for all fans.
In my cas 2 of the fans draw .12 A and the third draws .17 A.
So I need a power supply with a minimum rating of  (.12+.12+.17) = 410 ma or .41  A
The Pack that i chose is rated at 1.2 A so I am well below it rated capacity.

Step 1: Select Fans and Fasten Together

The first step in this project is to select the fans that you will use to make the array. Originally I'd hoped to make this a square 4 fan array however I only found three fans out of the ones that I had that were quiet enough to use.
Once you have selected your fans arrange them into the desired configuration and tie together with 4" zip ties. You could use longer zip ties however they will be wider an may not fit through the fan screw holes.

you can buy carbon filters, just like real fume extractors
