Anyone ever have this happen? Motherboard fire?

VRM on DFI Lanparty X48 LT blew out! I knew the board had a problem (no post LED) and hence had no CPU/Mem. (heck even the NB cooler was removed) Nice pink flames/flash from beneath the board so I removed the heatsink and tried again. (and again!)

Don't breathe that (motherboard smoke) it's pungent! D:

Can't say I've had the pleasure, but uh, breathing smoke from electronic components isn't exactly conducive to good health. I hope you took that video somewhere with good air circulation - especially if you kept hitting the button until it stopped sparking. 😀
 
Ive seen a PSU blowing flames, not a little bit either about 12-18" from the fan. I was working as a computer tech in the RMA dept of a local wholesaler and i got this PC back with a note saying "PSU on fire", i was like well it aint on fire right now so lets see what happens when i plug it in and hit the button. And they wernt kidding it was on fire alright, i set my desk on fire with it.

Yes - Enermax Liberty 620s can flame pretty bad if your line allows it.
 
That is one poorly designed board. They should have used an LC at the input to the VRM or at least a fuse. I have seen a lot of that lately though, relying on the PSU to catch failures. If the PSU is putting out 20A it is more than enough current to burn out fets, resistors or anything else before the PSU trips.

I'm starting to wonder if we need smoke detectors inside cases 🙂

Problem is space on the board and resistance is too high at the given current levels. Fortunately failures like this don't happen too often AND the PSUs used in such systems normally do trip off fairly quickly.

I had a fan wire that was wired to a spare 12V (HDD) connector that got pinched in a side panel and shorted out. Because the wire was so thin (24AWG) it heated up to incandescence and burned off its insulation while the system was running - fans pumping smoke into the air like a lawnmower engine that has too much oil! 😱
 
My Evga 680i from long ago burst into flames. I don't remember the exact details but Nvidia blamed me because they claimed there wasn't enough voltage in that area to do it. (Was some soldered part near the bottom of the board)
 
Had a Deer power supply (okay a buddy built it for us as a loaner and it was our first computer) torch a board.

Is that the antistatic bag under the motherboard? Isn't the *outside* of those bags conductive?
 
So this is the thread the video came from!
Was wondering what was going on in the video linked @ nefferthread 😱

Only incident I ever had with flames was a 6600GT that had one of the capacitors burst into a blue jet flame. Lots of smoke. Could see it through the case bay window.. Was really wtf'ed when I saw it. Luckily MSI rma covered it!
