Can I connect an 80 mm Computer Fan directly to electricity?

Can I connect an 80 mm Computer Fan directly to electricity? The thing is that I opened my cabinet because the computer shut down and it seems like stuff is getting really hot in there, now I have one fan inside the cabinet, its power supply has been cut off (possibly by the service center people), I want to re-start it, but I dont know how to do it inside the cabinet, so my question is, can I connect it directly to the electricity?

Do you want to connect the fan directly to the outlet in the wall or what?

 

Yeah I want to connect the fan directly to one of the outlets in the wall.

The fan has the wires, all I have to do is to get more cable and a plug. So will it work?

No man you will burn it .... it works at lower voltages ..... do you whant to make boom

 

I'd recommend against it, the fan is not built for that kind of output.

 

So any get around to it then?

You'd need hardware that would most likely cost more than the fan.

 

I think I'll just go buy a mini table fan and put it inside the cabinet all suspended to one of the walls.

I'm keeping the cabinet open until then, that should keep the computer cool.

You don't have any space to plug to your computer wires?

 

I've got a lot of experience in building custom computers and modding and i've seen all too many times burnt out power supplies

don't overload it, could burn your house down.. im not joking lol
invest in a larger one (don't get a generic, get a branded one)

 

Should I keep the cabinet open or closed? Because it seems like a lot of cool air generated by the fans is escaping.

1st i would what to know why the pc center disconnected a fan? that is what keeps a pc alive so they should have replaced the fan, you'll find that the fan is 12v just get a replacement and plug it back into the pc, is it the CPU fan or case fan?

 

Yeah you can connect it directly to the mains, but don't expect it to work for too long

BANG

 

you keep your computer in a wooden cabinet?
how big is it inside? and what kinda tower you have?

 

Its the case fan I believe, because seems like its there to exhaust hot air out.

The PC center probably disconnected the fan when they changed my SMPS, they probably put an SMPS that couldn't handle more than 2 fans (the cheaper one)

Oh and InfoH, from the cabinet I meant the cover of the CPU that you could unscrew to get access to the inner parts of the CPU, I took it out, should I leave it that way or put it back in?

i would look for a spare lead and plug the fan back in if you are having heat issues, failing that, look for a 12v transformer and cut the plug of that and the fan, connect the wires and use that, not the mains direct,

 

you mean the side of the case?
i'd keep it closed due to dust

as for fans

I have a midi-tower and I have 4 80mm case fans.. 1 top, 2 front, 1 back
then i have my fans on cpu and gfx
but my computer is on 24/7 so it needs good fans
the average user will get away with 2 case fans..
however dust is an issue on all computers i recommend a can of compressed air if you have quite a lot of dust inside your case

 

also wire management will help with air circulation,
just zip-tie bunches of wires together so they arnt all over the place,

or if ya wanna go extreme on it like I did drill a hole in your motherboard tray and rewire most of your wires so they are hidden underneath the motherboard lol

 

I'd pay you to build me the ultimate PC if I had access to you, seems like you've got some good knowledge Thanks for all the help

are you still alive?
