What do you mean wiring for the "mains?" I have many different power supplies I use. Some from cell phones, but the must powerful one I use is from an old laptop power supply. The wiring was simply from a PC's power supply I scavanged. For your fan, look for a 12Volt, maybe 1-2 amp. I can run all the fans I have off of this one power supply. I have 6 2inch fans, and 3 6inch I run all from this one...it is 18V 4amp.
go to walmart..and get a variable voltage DC charger in the electronics dept..(by cell phone chargers and what not.) it'll come with many different tips..and a adjustable voltage switch... 3-12V. Just cut the ends off..and hardwire it to the fans. THats what I do for my pc grow. Or get a pc power supply..and it'll give you a constant 12v of DC power
thanks for the info, and by wiring for the mains i meant hardwiring if thats what you call it. i have a couple of power supplys i could try and wire, one from a scanner and one 12v DC plug from i dont know where, i already tried to wire up a set of pc fans but it didnt work, i think the fans were dead cos im sure i wired it properly, and i would find it hard to go to walmart as i live in england
look around your house for an ac to dc wall adapter with the same voltage as the fans. Cut the head off the wire then strip and seperate the wires. Use those as the power source
get a power supply for a computer, 480 is good if your gonna run alot of things from it, alot of large fans, led's etc,take on of the power conections and short the Green wire with any Black Ground, That will let the Power Supply fire up without a motherboard, that why you must get the jummper of that. Then jsut plug the power cord into a plug, plug in your fans for the power connections comming from the power supply and get it in your room.
