RTX 5090 owner cuts hole in case for 16-pin cable, it burns anyway
An owner of a Gigabyte GeForce RTX 5090 AORUS MASTER ICE took unusual steps to keep the card’s 16-pin power cable from bending against the case side panel. The user installed a mesh panel with an opening around the connector, giving the cable plenty of clearance. Months later, the connector still suffered heat damage.
Modification didn't prevent overheating
The owner was using a Goghunters Fire F12 1200W White power supply. The mesh modification was specifically intended to avoid putting pressure on the 16-pin cable. The user says the cable was carefully routed without sharp bends or compression, yet the GPU power connector eventually began overheating.
According to the owner, the graphics card always operated at stock settings. Although the PSU was purchased around eight to nine months ago, the RTX 5090 had only accumulated around four to five months of actual use.
Resolution
The owner blamed the Goghunters cable and criticized the company’s RMA response. Goghunters reportedly first asked whether the card had been overclocked and offered a replacement cable. The company later requested that the PSU be sent back for factory inspection, with the process expected to take around one month.
The owner instead switched to a Seasonic 1600W PSU and added a fan blowing directly at the GPU power connector. The RTX 5090 was eventually sent to a Bilibili repair technician, who replaced the damaged 16-pin header for 600 RMB (around $90). A phase-change thermal pad was also installed, reportedly reducing GPU hotspot temperature by 18°C.
And it looks like that even the mesh sidepanel is gone. But will this make this RTX 5090 owner safe?
