LED question

[KoukiFC3S]

I got this Xbox 360 fan but it has an ugly blue LED. I wanna put a green LED there instead. Can I buy any type of LED? Ill look for a low voltage one but apart from that I dunno which one I need.

thanks

I am sure you can swap out the LED's not sure how but I have seen How To's on them some where. Tech Daddy has done alot of work with LED's maybe he can post something..

Just about any type will work although a much smaller might burn out from excessive current and a bigger one may light a bit dimmer. Just make sure you don't get one with a built-in series resistor. There is most likely already one in the circuit.

ok thanks ill look for one thats almost the same size as the old one

LED's come in 3mm and 5mm on the fans. Some fans mount a surface mount LED on the support bridges of the fan (small, rectangular diode), are your LED's in the circumference of the fan? or are they on the support arms of the motor on the fan frame?

Looking at this (http://www.lsdiodes.com/shop/index.p...c4ea504e891212)
and comparing the blue 3mm LED with the green 3mm LED, you will note that under typical load, they both source off of the 3.3v, and draw 20mA.

*IF* the vendor used a similar spec of LED, then moving from one LED to another should not be an issue. Keep in mind that many vendors produce LED's that have different current and voltage requirements, and that this list is by no means definitive. There are 12v LED's, 5v, 3.3v, 1.8v...etc, etc. etc... However the only way to be sure is to put a multimeter across the connection and see what the voltage and current draw is across the LED.

But, LED's are pretty danged cheap, and for a true "balls to the wall" DIY'er you could simply buy it and try. and if they burned out, you are out your time and the cost of the LED's... it will not damage your fan (assuming that the two circuits are isolated.



Or you could buy a green LED fan!

I know, I like doing things the hard way a few times too, just as an exercise in learning.

Hope this helps!
