RTX 5090 Overheating Fix Mod Posted by Reddit User
A Reddit user posted a fix for overheating RTX 5090 connectors, reducing cable temps under stress test.
Reddit user u/DallasGrave posted a fix for his RTX 5090’s overheating 12VHPWR connector. According to OC3D, the mod adds two supplemental 8-pin power connectors to the GPU’s original 12V-2×6 header via soldered connections.
Under a 48-hour, 550 W stress test, the modified RTX 5090 reportedly never exceeded 40 °C at its cable. The modification keeps the original 12V-HPWR connector in use but reduces individual conductor current to about 3 A.
Key facts
- Mod adds two supplemental 8-pin power connectors
- Reduces individual conductor current to about 3 A
- Under stress test, cable never reached 40 °C
