Unstable fan RPM, fan cycling on off noise.

[Dibbo]

The core issues are as follows:

1. Unstable and Fluctuating Fan RPM at any speed:
When the fan is set to a specific  percentage (e.g., 30%), the actual RPM is not stable. It fluctuates wildly by approximately ±200 RPM. This constant hunting for a stable speed creates an inconsistent and irritating audible hum or whine. This is not a smooth operation and indicates poor control logic in the fan curve algorithm.

2. Aggressive and Noisy Fan Start/Stop Cycling :                                                                                        

This is the most disruptive issue. Using the default "Balanced" or similar fan profile:

• The fan repeatedly cycles on and off at short intervals (every 5-10 seconds) when the GPU is under light load or idling.

• The fan ramps from 0 RPM (0%) to approximately 1050 RPM (30%) almost instantly. This violent, jarring spin-up creates a loud and very audible "whirr" or "surge" noise that is clearly noticeable from inside my computer case. ( Screenshots 

• This cycle repeats indefinitely, creating a distracting pattern of: Silence... sudden loud WHIRR... 5 seconds of fan noise... sudden stop... Silence... and so on.

Requested Actions:

1. Release a driver/software update that fundamentally fixes the fan control algorithm. This must eliminate the rapid on/off cycling and smooth ramps

2. Fine tuning the fan control to reduce rpm fluctuation.

Your fan RPM is all over the place, jumping ±200 RPM even at the same % setting. That’s why you’re hearing that weird hum. The fan keeps ramping up and down crazy fast when idle or under light load like silence…WHIRR…then silence again every few seconds. Not fun. What you can do now is update your GPU driver to the latest Intel Arc driver (32.0.101.8331). Drivers usually smooth out fan control. Tweak fan settings in Intel Graphics Command Center (IGC/IGS): Go to the Tuning/Performance tab. Switch from "Balanced" to "Silent" or set up a custom fan curve. Smooth ramps = less whirr. Check temps and load: Make sure this isn’t just happening under light load fans naturally ramp at different temps. BIOS/Firmware updates: Sometimes updating your motherboard or GPU firmware helps with fan behavior. Worth checking if updates are available.

i think intel engineering is aware of the rapid fan cycling + RPM swings, so a future driver update may fix it fully. For now, these tweaks should help cut down the noise and smooth things out.

My gpu driver is updated to the lastest one (version 32.0.101.8332).  this happens under no load. 
All firmware is up to date.
This issue is not mine only. Here is a post from a different user on the same problems.

Even with the latest GPU driver (32.0.101.8332) and all firmware fully updated, the issue still occurs under no load, which is frankly unacceptable. That immediately rules out user misconfiguration or stress-related behavior. This points to a driver-level or firmware-level defect, not an edge case. Worse, this isn’t an isolated incident. The fact that multiple users are reporting the exact same behavior, as shown in the linked Intel Community post, strongly suggests a known stability issue with the Arc platform, particularly around fan control or power management logic. When a problem reproduces across different systems, different users, same symptoms? That’s not coincidence, that’s a systemic problem. 

but, looks like a quality and maturity gap in the Arc software stack. For hardware that’s supposed to run stable at idle, instability under no load is a red flag. Drivers being “up to date” doesn’t mean much if the updates themselves aren’t resolving real-world issues.
