Acer swift x 14 fan LOUD constantly? Even when it's running nothing at all feels like max speed.

reptilesandmore

Hello!

Recently purchased an Acer swift x 14 laptop. It's great, except the fan is going CONSTANTLY. Even when it's running nothing at all, just being on or on a browser is enough to get the fans going at what feels like max speed. It's loud enough to be distracting, especially in lectures, and the 'silent mode' in quick access doesn't help at all. Is there a way to just turn the fans off completely when doing light stuff (literally just on word / docs).

Thank you!

Install Acer Quick Access or AcerSense and set User Mode to Silent.

You don't tell us which Swift X 14 model you have. Your full model number is usually on the same sticker as your serial number, it should look something like SFX14-xxx-xxxx. There is normally a minimum speed for the fans, and that can't be changed, but you can change profiles to allow the fans to spin up slower.

I’m experiencing the same issue, and it’s really frustrating! I have the Acer Swift X 14 (model: SFX14-72G-754M), and even when the laptop is idle with the CPU under 10% load, the fans are constantly spinning and are quite loud. I’ve tried using 'Silent Mode' from the Acer Sense app, and while it seems to make the device slightly quieter, the fans are still always on, which is distracting during light tasks like using Word or browsing.

I’ve also upgraded to BIOS 1.11, hoping for an improvement, but unfortunately, no change. Another issue I’ve run into is with the QuickSettings app, where the performance profile selector appears blank, so I can’t adjust the settings from there either.

Has anyone figured out how to fully resolve this or reduce the fan noise further? Any advice would be appreciated!

Same problem .... I think buying acer swift 14 was a big mistake for me .

Same issue, brought the swift go 14, the fan is so loud and starts automatically. I m badly in headache now. One of the worst decision of my life is buying acer

As stated before, since none of you have told us which model you have, we can only give general purpose suggestions. There have been a bunch of different SFX14 models over the years, in both Intel and AMD variants.

There are several reasons why your laptop fan might be running loudly: Overheating: Excess heat can cause your laptop's cooling system to work overtime to prevent overheating. Dust accumulation: Dust can clog vents and impede airflow, causing the fan to work harder.

I have the same problem. The fan is on constantly and loudly, even when the computer is not doing any heavy work. With silent mode it is bearable, just, but still much louder than I would expect. It's a new computer, so certainly not dust accumulation. CPU temperature hovers around 54°C, system temperature around 46°C. The computer is on a flat, hard desk, with plenty of air able to circulate. Specs are as follows:

Any help would be much appreciated.

Aha, someone told us which model they have. :) Too bad you didn't start the thread, so you can't mark answers… Anyway, for the SFX14-72G models here are the parameters used for the fans:

So, minimum fan speed is 1860RPM for all modes with ramp up starting at between 40 and 46C for the CPU and 40 to 44C on the GPU. Note the EC shutdown trigger change from earlier CPUs, they used to be 100C, not 115C, so these ones are designed to run hotter than previous chips.

I'm using Acer Swift SFG14-71 and the fan noise is very loud. I checked many software but they all didn't work. Finally I removed the fan physically and problem solved.

The computer temp was never too high due to large mental parts.

need a crewdriver set and triangular plastic piece, which can be found on aliexpress or ebay.

I really can't recommend anyone remove the fan. That is just so likely to cause thermal problems…

Hi @billsey,

Thank you for your detailed and thoughtful response—it’s much appreciated! 😊

Just to clarify, I did mention my exact model number in the original thread back in October 2024, but here it is again for reference: SFX14-72G-754M. This thread seems to confirm what I’ve been experiencing: the fan noise is still very loud.

I’ve tried several things, including adjusting the fan curve myself. My goal was to at least reduce fan noise under low-load conditions, but unfortunately, I haven’t had any success with custom fan-controlling software. Perhaps I haven’t found the right configuration yet.

While your detailed explanation of the fan curve was helpful, it hasn’t resolved the current issue. The fan ramps up even when the laptop is idling, with CPU temperatures measured at around 50–60°C (using HWInfo). The GPU is off during these measurements, so it’s really puzzling why the fan is so active.

Is there anything else you can suggest to improve this situation? It’s becoming increasingly frustrating, especially since I have an older device from another brand that operates much quieter—even with similar specifications. It’s difficult to understand how a new device like this could behave so differently.

For example, in a university setting, it’s nearly impossible to use this laptop during class because the fan noise is constant and disruptive. By comparison, other brands’ devices with the same CPU handle similar conditions much better.

Do you think there might be a firmware update or additional settings I could try? I’d love to hear your thoughts. Thank you again for your time and assistance! 😊

Information on my device:
Bios: V1.11
OS: Microsoft Windows 11 Home (64-Bit)Version (Build)24H2 (10.0.26100)
CPU: Intel(R) Core(TM) Ultra 7 155H
GPU: NVIDIA RTX 460 Mobile
RAM: 32GB
Software: All UpToDate on 18.01.2025 (including drivers and Intel Firmware)

As shown in the fan tables, even in silent mode, the minimum speed for the fan is 1860RPM and in silent mode ramping to 2000 at 52C, 2200 at 55C and 2500 at 60C. So the fan is doing pretty much exactly as it is designed to do. The Core Ultra chips do run hotter than older designs, with a maximum allowed temperature of 115C instead of the 100C for earlier versions. There is not a lot to be done to drop the sound level from the fan, since it's a result of the air moving through the system and without that the temperatures would run even higher. Maybe something like one of the laptop stands with fans built in would keep the temperature down enough for the fans to stay at the 1860RPM state, but even that is going to have some noise…

Hi @billsey,

I understand that this is the "design" choice, and Acer decided to turn this laptop into a leaf blower. However, I have a few questions:

I have access to other laptops, including older Acer models, and all of them are significantly quieter. I also noticed that the air coming out of those devices is much hotter compared to the Acer Swift X. On the Swift X, the air is at most warm but never truly hot. This makes me wonder if the temperature curve could be adjusted.

It seems ridiculous that in Silent Mode, the fan kicks in at 46°C, ramping up to around 50% of its maximum speed. I completely understand that the fan will get loud at higher temperatures, which is totally acceptable. However, it's extremely annoying that it spins up so quickly and aggressively even at low temperatures.

At 1800–2200 RPM, the airflow is clearly noticeable by hand, but the air itself is only mildly warm—because there simply isn’t that much heat to dissipate.

Is it possible to get a hint about which EC (Embedded Controller) manages the fan control? Ideally, it would be great if you could provide the READ and WRITE register addresses, so I can create a custom fan curve for my device. I fully understand the risks associated with making these changes.

TL;DR: Why does the fan ramp up so aggressively, even at low temperatures?

Thanks!

Your computer fan gets loud because of high internal temps caused by 100% disk usage, high RAM usage, dust and dirt in the vents, or lack of airflow.
If you notice the computer fan running constantly and making an abnormal or loud noise, this might indicate that the computer is not running as efficiently as possible, and/or clogged air vents. It is important to keep dust from accumulating in your computer and ensure adequate ventilation to help reduce heat.

@Axxo thanks for your response. The issue is not that the fan gets loud under heavy load-that's expected. My problem is the overly aggressive fan curve. The fan starts running at nearly 50°C and reaches almost 50% of its maximum RPM even when the laptop is idle. The device is not dusty, the air isn't even warm, and all resource usage (CPU, RAM, Disk) stays below 20% in idle.
I work in the IT industry and have already ensured there are no unnecessary processes running or thermal issues present. just want to adjust the fan control to reduce noise at lower temperatures.

billsey

I believe it is likely the speed control for the fan doesn't work below 1850RPM. That's not too uncommon for the small fans used in laptops. Unfortunately, though Acer does expose a memory map in their service guide, it lists most of the possible sources as "Motherboard resources", so no easy way to override the fan curves.
