Today an end-user (japan0827) who comes from Taiwan.
He unboxed the X79-UD3 mobo yesterday but when he wants to keep going
test about the mobo,suddenly amazing event happened!
The mobo X79-UD3 happens self-ignition and burn by it self!
He uses video camera and pictures capture to record all evidences!

Please have a look! and original link!

woah... that's crazy!
X79 VRM need cooling heh

IMO, that's sort of his own fault, particularly when we don't know the backround story (ie: voltages, clock speeds, etc).
ANY heatsink is in place to dissipate heat through the use of airflow. In a computer case, there's airflow moving over them which is why most people clue into the fact that out of case testing needs the same type of air movement.
See EVA2000's response above. That's the SMART way to do open system testing. In the video above, you see the clueless way.
Yeah, no airflow over the VRM results in toasty consequences

its not his fault. stupid gigabutt product.
It's like blaming Intel for a CPU catching fire because you didn't put a fan on the heatsink. Or perhaps suing McDonalds after dumping a hot cup of coffee in your lap. Thank god a higher court overturned the verdict and she didn't get a dime of the $3 million award.Originally Posted by Hondacity

Ive heard the McDonalds coffee thing for years and didnt know the woman didnt get the money, so thats cool!
if he didnt have airflow on his MOBO then it would be an unfortunate result of natural selection

Wonder how the "warr return" will work out on this?????

the motherboard had a heatsink.
Ever since time begun it has been known amongst overclockers that if you use water cooling you have to provide additional airflow around the VRM area, and if you are benchmarking or stability testing then are are looking at even greater load and heat which requires even greater VRM cooling.
What happened to that guy is a common mistake that newbies make.
I'd say it was more likely a faulty vrm or whatever that smd that blew off is (can't remember if brown smd bricks are resistor or capacitor).
Or, the fact that its a UD3, not a UD7, and may have been pushed a bit harder than it should have been without a fan on the VRM (as people have already mentioned). I'm not seeing this as being the fault of the manufacturer per-se. It's like me putting nitrous in a honda civic and expecting it to be fine (the analogy being- even though I have some cursory knowledge, I'm a noob at adding nitrous and the honda civic is an entry-level vehicle not made for those sorts of stresses).
i7 2600k, 8GB 1866Mhz DDR3, GTX560 Ti, Gigabyte Z68XP-UD4, CM Cosmos 1000 Case, and some green crap everywhere.So you're saying I could use my own pee as coolant?
most of the time the manufacturer would install heatsinks with them intending to have some air flow of some kind usually from case fans etc

Yes the heatsink will absorb the heat at the start, but once the metal reaches the same temperature as the heat source, there will be no cooling from the heatsink unless air blows at it to remove the heat.
defect board out of the box maybe, it not supose to be but sometimes it happen, no luck ...

Interesting set of comments regarding PWM cooling.
Has anyone ever seen a statement on a mobo box (ANY vendor) that says extra airflow IS needed? If the cooling is a must-have, why is it not included? Top-end GPUs don't come with passive heatsinks, expecting the user to add their own fan because it's so obvious.
I hope i'm coming across as devils advocate.

lol did anyone click on the links in his video description. He even did a really nice photochop with flames in one of the Taiwanese forums .... righttttttttttttt

I feel it's his fault, but then again...most high end boards today (save MSI) have had functional VRM over temp shutdown...

Not on a Mobo box, but I remember I had ASUS P5NT Deluxe socket 775, it came with an additional clip on fan for the VRM heatsink, it had a warning that the fan needs to be installed if water cooling is used.
But another point is Mobo makers don't need to say that, it says in the stress testing tools that excess stress will be applied and components can be damaged, a warning like that should make you research what it's about and how to stress test safely.
hmm...
I see nobody has commented about how USELESS the VRM heatsinks usually are.
They often make poor contact and the TIM can act as an insulator if its too thick or the motherboard bows due to poor isntallation methods.
With that said, the fault lies likely with a faulty component as there is not a rash of them blowing up yet, unlike the Asus Z7S-WS for example of which there were many that did blow up due to the poor VRM design.
All along the watchtower the watchmen watch the eternal return.
The most pointless post here.
It looks like a failed MOSFET. I wonder if Gigabyte is using substandard NIKOS MOSFETS in their high end boards. Would love to see a pic of the VRM MOSFETS without the heatsink on it to determine the make.
I can't belive Gigabyte is using this lousy transistor in such an expensive board.
Definitely NOT this guy's fault.
