![]() If you see nothing, the port is probably blown. If you see 12VDC the port is probably OK. You could set the fan port on the Quadro at 100% and put a DC volt meter on it. I am not sure what you mean by "connect fans to it (from d5)". The PWM fan ports use 12VDC so they are probably OK. Where did the smoke come from? Could you tell? If smoke came from the Quadro, the RGBpx port is probably fried. I can't think of any other reason that a cable would melt. ![]() If you somehow got +5VDC on the Data pin, that might also fry things. You may have fried the LED strip and the RGBpx port on the Quadro. If you got this backwards, it would reverse +5VDC and ground, which would probably result in smoke coming out. If you look at the pin-outs I provided, +5VDC and ground are on the 2 outer pins. As I mentioned in the post above, RGBpx cables are not pinned the same as factory made Molex Pico-Blade cables. Is it possible, that Quadro header is faulty somehow? I can try to connect fans to it (from d5) but I will be very unhappy if they will die after that test.ĭ. I can only assume that ledstrip was (probably not anymore) fully functional, as I've bought the block 2nd hand.Īny idea what could go wrong there? As mentioned, tried with multimeter and I'm sure everything was connected properly - GND to single pin in argb strip and +5 to the outer one of the other 2 pins. I've connected it to LED strip which was a part of AKWB waterblock to the Quadro controller and seen smoke literally straight away. Prior to installation I've checked everything, there were no shorts, +5 and GND where should be, data was in right place as well. Recently using same method, identical Molex cable (bought 5 at that point) I've failed miserably - +5V cable literally melted. I'll dig out this thread, as I've experienced some problem while moddind 3 pin argb to Quadro RGBpx header.Ī little over year ago I've succeed, connected 3x Arctic Cooling fans to D5 Next pump, all still working well.
