Shielding a fan

[Nate53085]

i need to mod a fan into my monitor because of heat blackout problems. Only problem is the only fan i have is unsheilded. I'm up for a mod, so what can i do to shield the fan?

Without the sheilding it makes the picture warble.

thanx in advance

maybe put the fan as far back away from the screen itself in the monitor casing... if that still doesnt work.. mod a tube that runs from the monitor side to a couple fans OUTSIDE the monitor far away that puts air thru the tube and into the monitor casing.. u can get those tubes for the chimney things for the exhaust thing above kitchen stoves or boiler chimney

i ll be doing a mod soon, a led fan inside the back of the monitor to have good airflow and light up the insides, and a window on the top to show off the insides

will try the fan outback. But i want to keep the fan inside. So piping isn't a possibility.

Use a DC fan, not an AC fan. THere is no way to shield a fan, unless you compoletely enclose it, then it wouldn't be much for airflow.

It is a DC fan thats the thing, plugs into a molex. Was gonna mod it 2 5 volts on the monitor .

i m just going to mod a wire othat runs out of the back of the monitor along the vga cable to one of my usb ports and get 5volts of power from that

that may not be a good idea...you wouldn't want to stress the vid card with the extra current draw the fan would produce.

someone else may want to prove otherwise, but it would be a concern of mine if I were doing it...so I'd want more input on any side effects it may cause.

The power wouldnt be coming from the vid card, it would be coming from a usb port

LOL...sorry, i must have said it wrong, i meant running along the vga cable but not taking power from it... meaning theres an extra wire that runs with the vga cable and power towards the computer and when that wire gets there, it'll run off an usb port

You don't need to have any kind of shielding, just stick it on there. It's actually a good idea, monitors can get pretty hot. Be careful of dust buildup though.

i found a motor in a dumpster 17 trinitron flat screen
it would flicker on and off 120 mm fan later no more flickering
but i run mine of a molex from in the case

it was probably caused by a bad solder joint. When the monitor would heat up and that particular component was at it's peak temp, the solder probably softened up and lost connection. The fan would have prevented that component from reaching it's peak temp.

you could also re-do all the solder joints on the bottom of the monitor's mainboard. Of course...this is only a good idea if you're good with soldering and are VERY board....
