    I have some fairly new fans that are quiet and have good airflow and blue led's. Currently they are mounted in my Antec 900 system. I just ordered a CM 922 case and I want to change the led's in three of the 120mm fans and install them in the new case, after I paint the inside black. I know I should just buy red fans, but I always like a challenge. I have been building systems for along time but changing fan led's is something I have never done. It doesn't seem like a big project but what I do need to know is what led's do I need to get and where do I buy them from. Using a voltmeter the voltage to the led looks like 3.3 volts and 3mm in dia. Appreciate any and all comments. Thanks

    Yes, you can run them straight into a 4 pin molex connector but just using the + and - terminals.

    drill a hole in the fans and use hot glue to secure them. Just make sure the molex uses the 3.3V / 5V and ground line, unless your LED's are rated for more.

    You may need resisors as athlonX2 pointed out...here is a tutorial I found gooling it. http://www.instructables.com/id/LEDs-for-Beginners/

    Are you sure these are bright enough? 18-20MCD is very not very bright as the high intensity ones run 2000-3000MCD. Have you personally used these leds?? If the're as bright or brighter than the standard ones that are supplied in the fans that is good. Thanks for the reply

    Would it be easier to just get new fans with red led's then you can give me the old one's.
