G-Helper Fan Curves Guide: Silent, Balanced, and Turbo Profiles
Stock ASUS laptop fan curves are tuned for safety, not for what most people actually want. Your laptop’s fans could be seriously aggressive while you’re browsing or dead weak at moments with the most heat. This article is going to go over how to use G-Helper’s fan curves to optimize your laptop, getting you the perfect profile that suits any situation.
If you’re stuck or confused on how to work through the details or are new to G-helper in general, it will go through the basics of each as well. No more having your laptop sound like a jet engine during a study session, or needing a cooling pad just to game with your friends.
What is a Fan Curve in G-Helper?
Fan curves are essentially the graphs that decide when and how powerful your fans are spinning, based on how hot your laptop gets. There are usually 3 main fans in your laptop: the CPU fan and GPU fan, with an extra mid fan for keeping any separate parts cool as well. Let’s check out the graph below for a quick rundown of the essentials.
Here is a simple fan curve for my laptop’s (ASUS G16 Zephyrus) CPU. Looking on the left side (Y axis), we have your fans’ RPM (Rotations per minute). The X axis shows exactly how hot your CPU (in this case) will have to be for the fans to work.
The way to change these is very intuitive, as it consists of a few “Nodes”. Moving these will decide the distribution of fan speeds depending on your system’s current heat.
How to Access and Edit Fan Curves in G-Helper
Now let’s check out how they actually look within G-Helper. If you don’t have G-Helper installed just yet, install it here. If you are hoping to get a quick guide on the installation, check out the G-Helper installation guide here. Once you’re on your basic G-Helper screen, click Fans + Power (on the top right) to open up your own custom fan profiles. Make sure your screen matches the one below.
Looking at this page, you will see on the top right a different selection of fan curves depending on your mode. The three main modes here are Silent, Balanced, and Turbo. As seen in the image, I’m currently in silent mode. Each of these modes should be switched out depending on your usage.
Here you will be creating your very own fan curves, specific to each mode and the way you want to use them.
Quick Tip – Make sure to click “Apply Custom Fan Curves to be able to edit.
Silent Profile (Battery / Quiet use)
When you’re working in a quiet library, scrolling Twitter, or just want to keep noise to a minimum –– This is the profile you want.
Overall, the silent profile is made to preserve as much battery as possible, while also keeping your system quiet when there isn’t a need for its fans. This is useful if you’re using your laptop for multiple hours a day, or simply don’t like the noise it can make at times. I used G-Helper for these same exact reasons, fine-tuning my fan curves to essentially get zero fan noise (as long as it’s safe). Listed below are the direct fan curves for the CPU, GPU, and Mid fans, giving you exact node placements so there’s no room for confusion.
If you find a liking for the silent mode because of efficiency towards battery life, check out my article on the best G-helper settings for battery life for more information on the topic.
Silent — The Recommended Curves
CPU Curves
- 0% fan from 0°C to ~60°C
- 30% at 70°C (gentle ramp)
- 50% at 80°C
- 80% at 90°C
- 100% at 95°C+
GPU Curves
- 0% fan from 0°C up to ~65°C
- 30% at 75°C
- 60% at 85°C
- 100% at 95°C+
Mid Fan Curves
- 0% up to 60°C
- 40% at about 80°C (Gentle)
- 60% at 95°C (Aggressive)
- Max at 100°C
Why these specific numbers?
Modern Ryzen and Intel laptop chips are designed to run safely up to around 95-100 °C, giving you a lot of room to breathe in quiet mode. Keeping in mind that light work or browsing keeps my personal laptop at around 45C on the CPU and 48C on the GPU, a limit around 60-65C will allow your laptop to run dead silent at low loads. Personally, this has been a game-changer for my own workflow, as I always found the stock-tuned fan curves to be utterly distracting while writing or even watching sports.
Balanced Profile (Strong but Efficient)
The balanced mode is going to be best used when you know your laptop’s gonna be performing under some load, and want to make sure to keep it cool while also not getting it too loud. I tuned this specific profile to maintain a low heat at most times, allowing you consistent low fan noise instead of inconsistent rising and falling that you’re probably used to. For this one, you’re gonna have to switch your G-Helper profile to “Balanced”, which was previously shown to be on the top right, and simply follow each node once again.
Balanced — The Recommended Curves
CPU Curves
- 20% from 0°C to ~50°C
- 40% at 65°C
- 60% at 75°C
- 85% at 85°C
- 100% at 92°C+
GPU Curves
- 20% from 0°C to ~55°C
- 50% at 70°C
- 80% at 80°C
- 100% at 90°C+
Mid Fan Curves
- 20% up to 55°C
- 50% at about 75°C (Steady)
- 80% at 88°C (Aggressive)
- Max at 95°C
Why these specific numbers?
As previously stated, I personally tuned the balanced profile to keep your laptop cool in times when you know it will be going under load. I did this by having a small noise floor, preventing any quick ramp-ups that could happen when using heavy software or playing a specific game. This profile I personally prefer when my laptops are plugged in, and I’m simply working on it, as there are always times it might be put under solid load.
Whether you’re running a coding program or downloading a large file, it should stay relatively cool at all times. This is unless you have to push your laptop to its limit, in which case please check out the final profile below, as it’s tuned for getting the most out of your hardware.
Turbo Profile (For Max Power)
The Turbo profile is built with one simple goal in mind: as much cooling as your system will possibly need, especially at times when you’re going to be under the biggest load. The key here is starting with a high base level, giving your machine no room to heat up before the fans can cool it down. This is best chosen when using very heavy software, creative tools, or when you’re gaming and trying to get the best quality.
Turbo – The Recommended Curves
CPU Curves
- 30% from 0°C to ~40°C
- 60% at 60°C (aggressive ramp)
- 90% at 75°C
- 100% at 85°C+
GPU Curves
- 40% from 0°C to ~50°C
- 80% at 70°C
- 100% at 80°C+
Mid Fan Curves
- 40% up to 50°C
- 70% at 65°C (Aggressive)
- 100% at 80°C+ (Max)
Why these specific numbers?
This profile is made for one thing: preventing the heat that you know is coming. Whether you’re gonna be testing your GPU to its limits in Cyberpunk 2077 or using your CPU to render high-resolution videos, this profile will be ready to handle any ramp-up in heat. Now, even if you’re not touching your laptop, you will see a performance boost in these high-intensity tasks due to the limited thermal throttling. A CPU will perform significantly better at 70 °C than at ~95 °C when under the same load, giving you not just better cooling but overall consistency in your laptop’s performance.
How to Save and Switch Between Profiles
Now that you’ve fine-tuned each of the 3 fan curves, the main benefit is being able to switch between each mode based on what exactly you’re doing. G-Helper automatically switches the fan curves when you simply click a different mode, allowing you the convenience of never having to edit them again. As long as the “Apply Custom Fan Curve” checkbox stays checked, your fan curves will transition smoothly between profiles.
How to switch modes
As seen on the left, your basic G-Helper menu has each of these modes on standby, so you simply need to open G-Helper from your tray and choose the mode that best fits whichever task you plan to do.
In around 30 minutes, you have now completely overhauled your laptop’s fan profiles, giving you not just better cooling, but better performance overall. Whether your goal was to save the most battery at light loads or to stretch your laptop’s gaming capabilities to its limits, these fan profiles are sure to fit any possible need. Of course, each system has its differences, so don’t be scared to play around with it if you find something amiss. These were simply the ones that worked the best for me, on my ASUS Zephyrus G16 – 2024 model.
