Quick Answer
Yes. BIOS updates wipe NVRAM to default states, erasing custom fan curves. New firmware versions frequently invalidate older saved profile formats. Photograph fan curve points before flashing or export profile to USB drive. After flashing completes, re-enter duty cycles and temperature targets manually or reload profile if firmware accepts file.

Does Updating Motherboard BIOS Reset Custom Fan Settings? Technical Overview
In the majority of cases, a motherboard BIOS or UEFI firmware update resets custom fan curves. The reset is a side effect of how firmware stores configuration data, not a defect. Fan control parameters live in the non-volatile storage (NVRAM, or CMOS-backed variable storage) that the firmware manages. Most vendors’ flashing utilities clear or reinitialize that region when writing a new image, because the layout of configuration variables can change between firmware versions. Manufacturer documentation from ASUS, MSI, Gigabyte, and ASRock specifies that settings should be reconfigured after a flash, and several utilities load optimized defaults automatically as part of the procedure.
The practical consequence is thermal, not cosmetic. Defaults often revert PWM fan headers to a generic profile (typically “Standard” or “Auto”) with a different ramp slope, minimum duty cycle, and temperature source than the custom curve. A tuned profile that held a CPU at 62 °C under sustained load with fans at 1,100 RPM may revert to a profile that idles at 30% duty (roughly 600 RPM on a 2,000 RPM-rated fan) and ramps late. Engineering evaluations of such reversions indicate transient temperature excursions of 5-15 °C until the curve is restored.
What a BIOS Update Resets
Understanding the scope of a reset requires separating the data a firmware flash touches from the data it preserves. The behavior varies by vendor, board generation, and flashing method (in-OS utility, EZ Flash, M-Flash, Q-Flash, or BIOS Flashback).
Typically reset or reinitialized:
- Fan curve points: temperature-to-duty-cycle pairs (for example, 40 °C / 30%, 60 °C / 55%, 75 °C / 80%, 85 °C / 100%) revert to factory profiles.
- Header control mode: the PWM versus DC selection (4-pin PWM at 25 kHz nominal versus 3-pin voltage control ranging from about 5 V to 12 V) may return to “Auto-detect.”
- Minimum duty and stop thresholds: zero-RPM behavior, start-up voltage, and minimum-speed floors are reinitialized.
- Temperature source assignments: a header mapped to VRM, chipset, or an external thermistor probe reverts to CPU package temperature.
- Response and smoothing parameters: step-up and step-down time (commonly 0.1-2.0 seconds) and hysteresis values return to defaults.
- Overclocking and voltage settings: CPU core voltage offsets (for example, a -0.050 V undervolt), memory profiles (XMP/EXPO at 1.35 V), and load-line calibration levels.
- Boot order and secure boot keys: may be reset depending on the vendor.
Typically preserved:
- Software-defined curves: profiles stored by operating system applications such as Fan Xpert, Armoury Crate, MSI Center, Gigabyte Control Center, FanControl, or SIV, because they are held on the OS drive rather than in firmware NVRAM.
- Hardware fan controller settings: standalone controllers (for example, Corsair Commander, NZXT, or Aquacomputer units) retain their own onboard memory independent of the motherboard.
- Stored BIOS profiles: some vendors preserve user profile slots, but compatibility across firmware versions is not guaranteed.
Technical analysis of vendor release notes shows that even when a profile slot survives a flash, the stored values can be invalidated if the new firmware changes the variable structure. In that case the board silently falls back to defaults or displays a checksum or “settings changed” message on first boot.
Why Firmware Clears Configuration Data
Firmware images contain both executable code and a setup variable database. When a new image changes the offset, size, or meaning of a variable, such as adding a fourth fan curve point or a new hysteresis parameter, the previous stored value can be misinterpreted. Clearing NVRAM prevents undefined behavior, such as a fan duty cycle read as 255% or a temperature threshold interpreted as 0 °C. A flash may also be followed by a CMOS clear, which resets the real-time clock and configuration data held by the CR2032 backup cell (nominal 3.0 V; replace below approximately 2.6 V).
Updates that include a new AGESA or microcode revision, which change CPU boost and power behavior, commonly trigger a mandatory reset. The change in power telemetry scaling can alter the temperatures reported to the fan controller, which makes carrying over an old curve inadvisable in some cases.
Saving Your Settings Before Flashing
Preparation takes about five minutes and removes the risk of reconstructing a curve from memory. The following procedure applies to nearly all current boards.
- Record the curve numerically. Open the fan control page (Q-Fan, Smart Fan, Hardware Monitor, or equivalent) and note every header’s control mode, temperature source, curve points, minimum duty, and hysteresis values.
- Photograph every relevant setup page. A photograph of each screen provides a reliable reference for voltages, frequencies, and timings, including CPU ratio, memory frequency (for example, DDR5-6000), and primary timings such as CL30-38-38-96.
