RTX 4060 Undervolt Guide: Cooler and Quieter, Same FPS

Published

On this page

The RTX 4060 is a frugal little card, but it still leaves efficiency on the table by running more voltage than most samples need. A quick undervolt in MSI Afterburner brings load temps down, trims its already-low power draw further, and lets the compact coolers most 4060s ship with spin slower and quieter — all at the same FPS. Here’s the curve editor method tuned for the 4060’s AD107 silicon.

RTX 4060 Undervolt Guide: Cooler and Quieter, Same FPS

The 4060’s small coolers benefit a lot from an undervolt — less heat means much quieter fans.

Why undervolt an RTX 4060

  • Quieter operation — the biggest win, since 4060 coolers are small and ramp up fast when they get warm.
  • Lower temps that help in tight mini-ITX and prebuilt cases with limited airflow.
  • Even lower power draw below its modest ~115W stock figure.
  • Steadier clocks in long sessions instead of brushing thermal limits.

What you need

  • MSI Afterburner plus RivaTuner Statistics Server — see our MSI Afterburner guide.
  • The on-screen overlay for clock, voltage, temp, and power.
  • A stress test and a demanding game for validation.

Step 1 – Open the curve editor

  1. Launch MSI Afterburner.
  2. Press Ctrl + F to open the Voltage/Frequency curve editor.
  3. Check stock load behaviour — a 4060 usually boosts around the mid-2600 MHz range near 1.0–1.05V.

Step 2 – Pick a target point

  1. Locate the 0.925V point on the curve.
  2. Aim to hold roughly 2650 MHz there as a starting target.
  3. This is a test point. Thanks to the silicon lottery, some 4060s manage more clock at 0.925V and a few need slightly less.

Step 3 – Flatten the curve

  1. Click the point at 0.925V and drag it up to around 2650 MHz.
  2. Hold Shift, select every point to the right of 0.925V, and drag them down so the curve flattens after your target.
  3. Click Apply (the checkmark). The 4060 is now capped at 0.925V while keeping a high clock.

Step 4 – Test for stability

  1. Run a stress test for 15–20 minutes, then play demanding games for 20–30 minutes.
  2. Watch for crashes, artifacts, or black screens — these signal the clock is too high for 0.925V.
  3. If it crashes, drop the clock at your target by 15–30 MHz and retest. If solid, you can edge the clock up a little.
  4. Once stable, save the profile and enable “Apply overclocking at system startup”.

How to revert

Click the reset (circular arrow) icon in Afterburner to go back to stock, or disable the startup-apply option and reboot. Reinstalling the drivers also clears the setting.

Expected results

Expect a noticeably quieter card with lower load temps and a small reduction in power, at unchanged FPS. The exact numbers depend on your specific 4060, cooler, and case — the reliable outcome is cooler and quieter for the same performance rather than extra frames.

Undervolting the RTX 4060 is the single best way to tame its eager little fans. Flatten the curve around 0.925V, validate with a stress test and a few games, then save the profile — you’ll get the same FPS from a cooler, quieter card.

Frequently asked questions

Is undervolting the RTX 4060 safe?

Yes. You are running the 4060 below its stock voltage, never above it, so there is no risk to the hardware. If you go too low the worst outcome is a driver crash or black screen that resets on reboot with no lasting effect.

How much can I undervolt an RTX 4060?

The 4060 is already a low-power card at around 115W, but most samples still hold their boost clock comfortably near 0.925V instead of the stock 1.0–1.05V peak. A target around 2650 MHz at 0.925V is a realistic starting point for many chips.

Does undervolting the RTX 4060 lose FPS?

Not when done right. You keep the same clock at a lower voltage, so FPS is unchanged. The 4060 often benefits from steadier boost in small or warm cases because it stops nudging against its thermal and power limits.

What's a good undervolt for the RTX 4060?

Try a flattened curve at about 0.925V targeting roughly 2650 MHz, then test. Because of the silicon lottery some 4060s will hold a higher clock at that voltage and others will need a small reduction, so treat the figure as a starting test point.

Will undervolting void my RTX 4060 warranty?

No. The undervolt is a reversible MSI Afterburner setting that makes no permanent change to the card. Resetting Afterburner or reinstalling the GPU drivers restores stock behaviour entirely.
