Swift Edge 16 Loud Fan during everday tasks on Silent Mode

Long Story Short:
I got the Acer Swift Edge 16 because of its large screen and very low weight but i really regret it. Won't buy from Acer again. They got really good hardware but the software is unacceptable for its price. Even if you put the laptop to "silent" mode from Acer's software and best efficiency from windows, slightest action causes to fans to spin up annoyingly. And theres a crackling noise that is sometimes present near the fan which is audible in silent environments. If you are considering this model and you dont have LG Gram, consider asus vivobook 15.6 oled. It is a little heavier but wont have this fan issue and thus wont be a regret. (My friend has 14" oled asus and it doesnt have the fan issue)

Long Version:
We got on the market to buy the largest and lightest laptop and found the Acer Swift Edge 16. But the laptop has a very annoying fan problem. The slightest action you take causes the fan to spin up audibly. For example opening; a new chrome tab, windows settings, youtube, word, or even moving the mouse while the laptop has been idle for a while. And this is with the laptop set to silent in Acer Sense application and best power efficiency in windows power profile.
I know about this stuff. I downloaded Hardwafe Info to check the power consumption, temperature etc. of the cpu. And I looked up other threads with people having the same issue. The cpu is silent at 40C. The moment cpu hits 44C, fans ramp to 3400rpm. So you go from complete silence to an annoying fan noise. The noise increases with every 4 degrees. Lets say there was a slight cpu load and temps got up to 48C, then you are met with a fan noise as if you are gaming / rendering.
This honestly sucks. If you look at laptops with proper software, like ASUS, the fans are still inactive at 50C. As they should be. Or if you look at macbooks with fans, they start to SLOWLY ramp up the fans when the cpu hits 60C. They dont jump from 0 to 3400rpm and annoy you like with this Acer.
Since they bothered to put "Silent - Normal - Performance" modes, why didnt they just put a truly silent mode? This cpu (7840U) gives more than satisfactory performance around 7-10 Watt range. Therefore it could be cooled passively at low demand. And if the cpu hits 50/60C, they could slowly ramp up the fan like 1000rpm, 1500rpm and throttle the cpu. But this laptop jumps to 3400rpm at 44C instead which is just utter stupidity. It would be more logical if they called the fan modes "Performance - Higher Performance - Highest Performance".
I did download the latest bios from Acer's page, V1.64. But there wasnt any improvement.

I regret buying this laptop. Screen is spectacular and 7840U is an amazing chipset. And its so light. But this little, completely software related issue, kills the whole experience. You cant return items where i am so this is more than infuriating. I wont trust Acer with expensive purchases anymore.

    The Swift Edge 16's fans can be loud even in Silent Mode during everyday tasks, but this is often due to a combination of factors like the device's cooling design and the level of activity.
    Here's a breakdown of why this might be happening and what you can do:-

    Why the fan might be loud:-
    Cooling Design: The Swift Edge 16's cooling design, while efficient, may be more susceptible to noise during heavier tasks.
    System Load: Even on Silent Mode, the fan may kick in if the system is under load, like running multiple programs or playing videos.
    Silent Mode Limitations: Silent Mode focuses on reducing noise, but it also limits performance to some extent, which can affect how quickly the system can handle tasks.

    Things you can try to reduce fan noise:-
    Close Unnecessary Programs: Running fewer programs can reduce the workload on the CPU, leading to lower fan speeds.
    Adjust Power Settings: Explore your power settings to see if you can adjust the CPU's power usage to a lower level, which may reduce fan activity.
    Clean Vents and Fan: Regular cleaning of the vents and fan can prevent dust buildup, which can make the fan work harder and louder.
    Use Acer Quick Access: If you have access to Acer Quick Access, try enabling the "silent mode" option within it.
    Consider an External Cooler: If you frequently perform demanding tasks, an external laptop cooler can help keep the laptop cooler and reduce fan noise.

    Acer's return policy in many countries is 15 days from delivery, in the Philippines it is one week. I use 2 laptops the Swift X SFX14-51G-7003 and Asus Vivobook OLED K3502ZA and the cooling fans are equally quiet, I like the Swift better because of the very light aluminum body and the Asus is twice as expensive. There are reports about a noisy fan after a BIOS update for the Acer Swift Edge 16, check for BIOS updates and also this thread: SFE16-43-R5U9 2023 nosy after software upgrade. CPU usage is about 2-3%, and fans still runs noisy — Acer Community

    You don't tell us which Swift Edge 16 model you have. If it's one of the Intel based versions, using the new Ultra chipsets, then it will run hotter than older designs, and that typically means the fans will be spinning faster, so generating more noise. That is inherent in the new chipsets and there is little that Acer can do with these designs to make them quieter. Hopefully as Intel continues development on newer chipsets they will lower the heat, but for now all the first and second generation Ultras will continue to run hot in laptops.

    If you have one of the AMD based designs instead, they also tend to run hot, but not as hot as the Intel. I believe those are running two fans, which does tend to double the noise…

    Your full model number is usually on the same sticker as your serial number, it should look something like SFE16-xxx-xxxx. That will give us a better idea as to what you actually have.

    Its 7840u. SFE16-43. Thing is, as I have greatly detailed, it doesnt run hot, fans are simply too aggresive. They could have adjusted the fans to start at a lower rpm and at a higher temp, like 50 C and it would have been perfect. I wouldnt mind a slightly warmer keyboard. Afterall, thats what different fan profiles should be for. User preference.

    Anyways, i took display down to 60hz and that greatly reduced fan noise. It still cycles on and off watching 1080 60fps video though. Whereas it would be always on with 120hz.

    OK, so AMD based then. Here are the fan modes:

    As you can see they aren't kicking it in until the CPU gets into the 40s, but ramp up a bunch by the time it's in the 50s. I'd guess they are working off guidelines from AMD for where the temps should stay, so there's not going to be a lot to be done.

    I have seen these graphs as my original comment has data from them. Based on my experience; right temperature is the initial threshold where level is activated, and left is exit thershold where its deactivated/lowered. This aligns with my experience where level 1 initializes when cpu hits 44 and deactivates when it hits 40, in silent mode.

    "As you can see they aren't kicking it in until the CPU gets into the 40s" The cpu is pretty much always at ~40C on idle and 40s on the light loads. A proper calibration would allow silent or near silent operation under light load, aka web browsing / watching video. 3400 rpm isnt silent unfortunately.

    Very likely the CFM curve on the fans is such that slower than 3400 RPM doesn't move enough air to actually provide cooling… If it really bothers you I suppose you could look into other fan designs to see if there are any that provide more air movement at slower speeds in the same form factor…

    The issue isnt really airflow. I believe the issue is Acer's insistence to keep surface temperatures down. I get that since the laptop is thin, more heat is transferred to the bottom panel and keyboard. It is noticable. But i wish silent mode prioritised noise rather than surface temps. There is not much of a reason to put different fan modes if they are %95 same.
