Perfect RTX 5090 FE Undervolt! | Guide Cooler, Quieter, Better Than Stock

Want to make your RTX 5090 FE run cooler, quieter, and more efficient — without sacrificing performance?

In this video, I’ll walk you through the exact undervolt settings I use on the RTX 5090 Founders Edition. With just a few tweaks in MSI Afterburner, I was able to drop GPU temps, reduce power consumption by over 100W, and actually score higher in 3DMark Steel Nomad than the stock profile.

🔥 Stock Score: 14,217
🔥 Undervolt Score: 14,587
🔥 Peak Temps: 72°C → 67°C
🔥 Power Draw: 567W → 464W

I’ll show you step-by-step how to safely undervolt your 5090, explain why this specific voltage/frequency curve works, and show real-world results across benchmarks and games.

💡 Whether you’re building in a small form factor case like the FormD T1 or just want to maximize efficiency, this is a must-try tweak for your 5090 FE.

🔧 Tools Used:
• MSI Afterburner
