NZXT H1 PCIe Riser Replacement Kit Hands-On

In response to reports of the PCIe riser cable of its H1 case posing a fire hazard, NZXT in February 2021 instituted a recall of the case in the U.S. and Canada. The flaw in the component's design came to light in early-2020, but it was only by November that it responded to the issue. In its original design, the PCIe riser component was improperly grounded, and a short-circuit could result in a fire. NZXT's first response to this was sending out non-conductive Nylon screws for the users to replace the metal ones the part originally shipped with. This solution wasn't found to be effective, and resulted in a product recall this February. Regulators in the U.S. and Canada directed NZXT to send out free repair kits to existing owners of the H1, along with disposal instructions for the entire case, if the user wishes to discontinue use. We got our Repair Kit, and decided to go hands-on.

The NZXT Repair Kit, and replacement riser card appears to be one of the most solidly built PCIe risers in the market. Thanks to the crypto-mining boom, the market is flooded with PCIe risers of all shapes and sizes, and the NZXT riser looks to be among the better designed ones. What sets this apart from the original design is that now, the downstream (female end) of the riser comes with grounding rings around the mounting holes, similar to motherboards. These are bits of exposed copper that facilitate contact between the ground layer of the PCB, with the sheet-metal of the case. The original design lacked grounding pads on either side of the PCB, and when installed with metal screws, certain PCB traces could get shorted, causing them to heat up and start a fire. NZXT's first solution to this problem was non-conductive Nylon screws. End users with an H1 case, can request this riser cable from here.
