Key Takeaways
1. Lack of Alternatives: There are no complete Acer-specific substitutes for NitroSense or PredatorSense, making it hard for users to find suitable tools for performance and system management.
2. User-Friendly Options: Fan Control is a user-friendly application that allows users to set fan curves based on temperature readings, providing some control over fan speed.
3. Limitations on New Models: Newer Acer laptops restrict fan control at the BIOS or embedded controller level, preventing third-party applications from accessing necessary sensors.
4. Custom Configuration Challenges: Creating custom configuration files for tools like NotebookFanControl is difficult due to Acer’s restrictions and the lack of available profiles for newer models.
5. Partial Solutions: While tools like MSI Afterburner and NotebookFanControl can manage some aspects of performance, they do not fully replace Acer’s proprietary software for comprehensive control.
We’ve had it pretty good with G-Helper, a fantastic open-source app discussed in the last part of this series. Made and updated by a single developer, it’s so sleek, straightforward, and effective that it made us forget about Asus’ official software, Armoury Crate and MyAsus, along with their inbuilt tracking and advertising features.
Finding Alternatives for Acer
Looking for a similar tool for Acer laptops is proving to be quite the challenge. There doesn’t seem to be a complete Acer-specific substitute for NitroSense or PredatorSense, which includes options for performance profiles and system management. Instead, users are often directed to general fan control apps like NotebookFanControl (Github) or another program simply called Fan Control (official website).
User-Friendly Options
Among these, Fan Control is the easier one to use. Its main advantage is the capacity to set up fan curves based on temperature readings—and even merge multiple sensors into a singular control point.
For instance, you might set a rule like “increase fan speed to 60% when the temperature goes over 70 °C” and utilize both CPU and GPU temperature sensors (or other ones) as triggers. The component that hits the temperature limit first will initiate the pre-established fan reaction.
Limitations on New Acer Laptops
This method works nicely on desktop PCs—and might work on older Acer laptops too. However, on newer Acer models, the situation is quite different.
On our Acer Nitro V 17 (review) and other recent Acer gaming laptops, Acer restricts fan control at the BIOS or embedded controller (EC) level. Consequently, firmware-controlled fans can only be accessed through NitroSense or PredatorSense. Third-party applications cannot read or manage the required sensors directly.
NotebookFanControl (NBFC) doesn’t function right away. Instead, it needs a special configuration file—usually community-made profiles that are designed for specific laptop models. The issue here is that most available config files are for older devices, while profiles for the latest laptops are extremely limited.
Creating Custom Configurations
Making your own config file is a tricky task, even with the help of the Github wiki. It involves checking specific registers, which becomes significantly harder—or even impossible—due to Acer’s EC restrictions.
Another popular universal fan control tool, SpeedFan, faces the same challenges on modern Acer laptops.
This leaves MSI Afterburner as a less-than-ideal alternative. It’s less than ideal because it only manages GPU settings, not the CPU. Nevertheless, the 43 MB application allows users to set profiles for GPU clock speeds and fan operations, giving at least a bit of control over performance and thermal management.
For Acer desktop PCs, NotebookFanControl and Fan Control can act as partial substitutes. While they don’t come close to matching G-Helper for Asus machines in terms of polish, they can still handle a lot of basic tasks.
Sadly, Acer locks fan control on the majority of its current gaming laptops at the BIOS or embedded controller level. Therefore, to our knowledge, there isn’t a solid open-source alternative to NitroSense or PredatorSense on Acer laptops today. MSI Afterburner can manage GPU settings to some degree, but it doesn’t adequately replace Acer’s proprietary control software.
