GPU Undervolting & Noise Reduction – Redneck Noctua Mod 3070ti

2 Comments

  1. Hey everyone,

    Just wanted to share a simple and honest review of why I love Noctua products.

    Without Noctua fans, I couldn’t have achieved the same level of silence. Sorry, EVGA, but the original fans felt like cheap toys in comparison.

    Overall, I’m thrilled with the mod. Installation was a breeze—I simply plugged the fans into the motherboard instead of using the GPU fan pins (EVGA has a reverse layout).

    I use Argus Monitor to control the fans. Interestingly, they can spin up at just 13% (~169 RPM), providing enough airflow to cool the GPU at 30-40% usage. The CPU fan behaves similarly. The PSU’s fan (not Noctua [yet!]) kicks in when the system draws at least 300W.

    Despite needing more cooling for more GPU power, my undervolted 3070ti stays cool with the two NF-P12 PWM fans spinning at just 5-600 RPM. The original 3×9 cm fans had to spin at least 1200-1500 RPM for the same performance.

    It’s unbelievable! I finally reached my goal.

    Now, I’m sitting near a dead silent PC with enough raw power even for gaming.

    Here’s my full setup:

    CPU: AMD Ryzen 5800X @ 4.8 GHz, 1.25 V cooled by Noctua NH-D15S
    GPU: EVGA RTX 3070 Ti FTW3 Ultra @ 1975 Mhz, 930 mV, Mem +500 MHz deshrouded with 2x NF-P12 PWM
    RAM: G.SKILL Neo 4×16 GB 3600 MHz @ 16-19-19-36-58 1T
    PSU: FSP HYDRO PTM PRO 1000W 80PLUS Platinum Modular 14 cm fan
    Monitor: SAMSUNG LC32G5XT 32″ 2560×1440 @ 144 Hz
    Motherboard: ASUS TUF Gaming B550M+ Wi-Fi
    NVME: Samsung 970 EVO Plus 500 GB
    NVME: Apacer AS2280P4 1TB
    Case: NZXT S340, top NF-A15, rear NF-P12, front 2x NFA15
    Peripherals: Microsoft Classic IntelliMouse, Cherry MX Board 6.0, Logitech G29

    Inner me wants to say chromax the GPU fans. No idea why.
