We're demonstrating how NZXT's H1 case (or BLD prebuilt) can catch fire, diagnosing the electrical problem, and discussing whether it remains unsafe even with the new screws.

In this content, we'll feature Steve trying to initially trigger the fire problem described by NZXT in its H1 case, followed by Patrick Stone diagnosing the issue, then Patrick Lathan mapping the PCIe slot electrical wiring. In short, we believe that NZXT is shorting 12V to ground, which can turn the trace at fault into a tiny heating element that ignites a fire. If you have not yet replaced the screws in the riser, please do it immediately -- but we're also concerned that the riser itself remains problematic since we believe there may be an exposed trace in the PCB.

NZXT RESPONDS: mndown.info/fast/video/v6Omiaygp6yOq30 Part 2 is up: mndown.info/fast/video/y5-3pZeKs4Kwoqs If you have one of these computers or cases, even if you have not experienced fire, please replace both screws immediately with something non-conductive. We would also personally advise replacing the PCIe riser in its entirety and getting rid of the included one in a way that it can't accidentally be used with a metal screw in the future.

@Player Slot Available You are be good if that picture is what yours looks like. The plastic screws can't conduct electricity so the electrical short as shown isn't possible. Well, as long as the plastic screws are used. Who knows in 10 years if someone doesn't replace those with steel screws. Or whatever.

Lets see, the riser is grounding out, yet their answer is to use a plastic screw, to secure the metal riser, to the metal case, that has a metal cased power source attached, yep, that'll stop the loop, like replacing the bolt in the ground clamp on your car with a plastic one.

Look at that PCB at 26:26. That's not a fire yet; the real fire doesn't start until 26:50. It looks like the PCB 12V plane is glowing red-hot like a lightbulb. You need to be well over 500 degrees C to get it to glow that bright. Which makes sense after a little napkin math. Ohm's Law says a Current in a circuit will equal the Voltage divided by Resistance, or I=V/R. I heard someone call out 'point-three' before the fire, so I'll use that for resistance. 12V/0.3Ohms = 40 Amps. 40 Amps is A LOT of current. Most household circuit breakers will trip at 15. The reason for this is that Current makes things REALLY hot. The Power dissipated in a circuit equals Current SQUARED times Resistance. So 40 Amps Squared times 0.3 Ohms is 480 Watts of power, all going right through that PCB with no heatsink and no thermal throttling. No wonder that shit lit up.

The animation at 21:10 of the screw going in and the threads rotating to contact the 12v trace is not correct. The threads will make contact at the same depth no matter how the screw is turned. The animation shows it operating like a drill bit Imagine the pcb has female threads. The screw going into it is going to follow those. What may be happening is that the screw can move side to side enough to contact the trace, or when screwed in very tight, it's squishing the 12v trace into the ground path. Beyond the defect pcie riser, I'd consider this a bigger failure of the power supply overcurrent protection. This is exactly why that feature exists. The traces are very small and overheat with very little current but the overcurrent should be sensitive enough to detect on the ground plane.

In theory if the top screw were to bite into a PCI data lane and the bottom into a 12v plane, you could fry both the cpu and the gpu aswell as burning down your home

if you look at all the predrilled holes, the hole they used for mounting is larger then the rest. I assume somewhere in they blue printing speciation's of the case a engineer used the wrong size hole and screws when designing the case and I believe that is where you get your short from the screws cutting into the pcb. Something to look into when the new case comes. i would also look and ask did someone drill to oversize the hole they use for mounting the pcb to the case to fit a larges screw who know just putting it out there

I have warned about NZXT multiple times on MNdown and the GN site but it is good to see GN is starting to have caught on. NZTX is known to sell faulty and dangerous products. Their normal way of doing business is how they did with the CAM software (to this day still not working as advertised and the forum they shut down after massive complaints is still down). I like GN but as long as any NZXT product review isn't started with a HUGE caveat I can't take anything said as neutral reporting. If 90% of products are crap or moneygraps then a test of the 10% without a warning is clearly very biased journalism.

Sounds like the pcb board trace and the diameter of the screw is the issue. If the pcb hole diameter was larger than the screw there would be no contact. NZXT was using a counter sunk screw anyways so why not have a larger hole in the PCB.
P Wood

your analysis is silly, and overcomplicated. The real problem is not that silly screw, and that "explanation" about the "loop" is nowhere near accurate. The real problem is the PCB design. No way should a +12 trace be close enough to that hole to contact that screw. There was no reason for any trace to be within 1/2" of that hole. Three videos and I covered it in seconds. That oversized screw only brought the real problem to the fore....

Kind of an iffy design to not have any separation between the trace and screw hole, in such a way that the ridges on the screw would cause a short to occur if arranges in the right way. Also I would be checking if they used the same riser cable/board in other cases aside from in this specific model as well. Check the board and revision no and see if any matches.

I do PCBA design semi-professionally. The mere idea that someone would have left a power trace so close to a mechanical edge is probably the most amateur mistake anyone would do. My guess is that one of the inner layers of that board fab is a plane on the 12v rail with ZERO edge clearance. The "engineer" who laid out this board was probably using MS Paint, at best. All of the layout tools I'm aware of (including open source FREE) have design rulesets which can flag or even limit possible errors and safety issues. Even if the rules are disabled (not advised) drawing a screw hole has some elementary constants. Like, NOT putting power traces anywhere near an external contact surface unless it's part of that circuit. Using the wisdom I learned at 4 years old by trying out a pair of wire cutters on a lamp cord... while it was plugged in... Put stuff in between 2 metal things with electricity so they don't touch. Personally (space permitting) when I include a screw hole in a layout, I size and locate traces and planes outside the diameter of a domed screw head. Regardless of layer. That way if some goof decides to ream the hole out a bit for slightly bigger screws, it'll help avoid a flaming disaster.

A rare occurrence doesn't mean a small percentage of units have this problem. Every unit has this problem. It's just a small percentage had the screw in the right position to trigger. That's not okay. Or safe. A small amount of fan or pump vibration over time could cause a tiny shift in the screw at any given point.
