then i put the bottom on, and only the left fan came on. i took the bottom back off, and the right fan came on for about 2 seconds and then turned off. does this sound like a fan issue or something on the mobo? i don't want to waste money on a talisman or some other replacement fans if they're going to do the same thing...i have no soldering experience so the 12v mod isn't really an option at this point

Try wiggling the cable and make sure its plugged in all the way.

ive had the same problem once....see ur fan has 4 little squares, look into them and most lickely 1 of them is not level with the others, thus not making contact with the power. Just push the wire so it becomes level with the other wires
level with the other wires? i don't follow. oh you mean on the connector that goes into the power plug on the mobo?

Are you powering any other fan/device from the main fan plug?
yeah i have 2 sets of led's, but even when i took those off it still worked intermittently...either way i ordered the talismoon fans off ebay, i think i might cut a hole in the top of the case as a vent for the processor's heatsink...i have an extra case anyways...

The transistors are Q3M1 (powers fan close to video plug) and Q3A2 (fan by power plug)
The part number is BCP51, I sell replacements or can install them for you, it can be done with a regular soldering iron but is much easier with a SMD reflow station

If you were running LED's off of the fan plug you may have damaged the transistors on the motherboard that control the fans, they can be easily overloaded and damaged.

could it be possible to damage a transistor to working sporatically though? i thought it was kind of an on-off thing, not a sometimes on sometimes off thing...and i can't solder jack lol...did it once for a project in high-school, since then, nada
*edit*
and i've had the led's installed the same way for at least 8 months with no issues...not sure if that matters or not

It really doesn't, the constant strain on the 12v line probably just got the best of it and finally it decided to go (IMG:style_emoticons/default/wink.gif)
