That's crazy! I'm not entirely surprised by it, since I know how hot those chokesget... but Icurious about a couple things, if anyone knows the answer?Is it the Fan Header that melted? It kinda looks that way to me in this pic, as there looks to be at least 3 wires and heatshrink tubing:Then in this pic... What I've traced in red, is that some sort of metal backplate, or just the copper ground layer that is now visible?Originally I was thinking it was a sticker due to the text in blue, and that is why it caught fire in the first place; however... No, that's definitely just a resistor, same as on the other side:To my untrained eye, it looked like it's the fan header and that they routed the wires between those two 1RD 1818 chokes.As for why it would've caught fire under a simple load like browsing the internet (unless it wasYouTube vids?), the only thing I can speculate is that the heatshrink tubing was the "good" kind that has a glue in it, except in this instance it's that glue which ended up catching fire. I've used that kind of heatshrink before, but I don't have any experience as to it's resistance to prolonged high heat like what those chokes can produce. The glue in those obviously doesn't take much to melt and "flow", as I've just used a cig lighter, but I also only expose it all to heat long enough to shrink and ooze the glue a little. Exposure to continual heat could easily cause it to break down and dry out in which *poof*; or break down and emit a flammable gas or resin, in which *poof*.I'm sure any company, front-page [H[ exposure or not, would warranty it though. Any that wouldn't, I'd like to know about so I can avoid buying anything from them!
