Adding LED to GPU fan?

[tobsmonster2]

Spotted this today and decided I'd like to do the same to a reference 570 or 580. Any ideas?

That's a KFA GTX 570 in the picture.

Thanks tealc. I was pretty much thinking of cutting maybe 3 or 4 little holes on the 'inside' of the shroud, and poking them through there. The other issue would be how I'd power the LED's .

I suppose if I opt for a second hand 570 , I'd just find a 12V or 5V source on the board and solder to that. Wouldn't mind voiding my warranty on something that cheap. If I got the 580 however, I was thinking I'd like to mod my way into the 4pin fan connector and have a go at stealing 12V from there .

Any idea which of the pins are which? And what exactly is the connector called? Any attempt to research a 4pin fan connector points me to the 4pin PWM on motherboards, and searching mini 4pin returns much of the same.

Thanks tealc, you're an absolute star. Just noticed from your sig, it was your thread that gave me the idea of cutting little holes for the LED's .

If I can find a supplier of the connectors it wouldn't be too difficult to split off power for the LED's and run them through a switch. Thing is though, I'd still need to solder directly to the board at some point for a higher amperage source. At which point I might as well skip the connector completely; though having the LED's brightness scale with load/heat would be pretty cool so the transistor idea isn't totally off the table .

Either way, if I do get anything done you'll be the first to know . Thanks again.
