I want to put a cathode behind my new LCD to accent it, but it's too bright on 12v+, and I know you can put fans on 12v+ and 5v+, but what about 3.3v+ and with cathodes??

More about : cathodes fans

some fans will do 3.3(My Zalman cnps 7000alcu start on 2.6volts.

The cathodes will try to draw as much current as it can(this is what happens when a ballast gets lower voltage. its bad for it) get and most likely just kill the ballast(little box the power goes into first). If it does manage to light it will not be any dimmer....

This is the same as a fluorescence light. they normally do not dim either...

You may be able to use some kind of diffuser to dim(by blocking) the light....Try some kind if white semi translucent plastic(like a plastic lid from a container) and see if that dampens the light enough to make it more acceptable...

Um, ok? I don't even use xfire anymore. It's childish and they don't support anything useful.

the complaint is not about Xfire, its about your Xfire blogs and the racism written there.

This is neither the time or the place...but to anyone who is wondering, I consider hoodlums, gang bangers, degenerates, criminals, and sub-humans the n word, and people seem to think it's just to degrade blacks.

I am not racist, and if you look at the blog, it in fact is a question as to why the word is considered racist, when in fact, hip-hop people say the word in a different way to each other, but like I said, this is neither the time nor the place...reply to the blog if you want...don't bring it here.

When your a minority (I am since I'm white) then I suppose you will get it.

I live in San Jose, California, and it seems like the city is filled with criminals and drug addicts.
