An overheating ASUS TUF Gaming A15 can throttle your game's frame rate, cause sudden shutdowns, and shorten the lifespan of your components. If your laptop's keyboard is uncomfortably hot, the fans are screaming constantly, or performance dips during a gaming session, these steps will help you get it under control.
Switch to Silent Mode in Armoury Crate
This is your quickest fix. The TUF A15's Armoury Crate software is your command center. Open it and switch from Performance or Turbo mode to Silent mode. This immediately lowers the CPU and GPU power limits, which drastically cuts down on heat and fan noise. It's perfect for general browsing or work.
When you're ready to game, you can switch back to Performance mode. I'd save Turbo mode for very demanding titles, as it pushes the hardware hard and generates the most heat. This simple toggle is the most effective first step.
Clean the Air Vents Thoroughly
Dust is the silent killer of gaming laptop cooling. The TUF A15's intake vents on the bottom and exhaust on the sides and back can get clogged. Power the laptop off, grab a can of compressed air, and give those vents several short bursts from the outside.
For a deeper clean, you can carefully remove the bottom panel. Once open, use the compressed air to blow dust out of the fan blades and heatsink fins. Don't use a vacuum cleaner, as it can create static electricity. A good cleaning can drop your gaming temperatures by a noticeable 10-15 degrees Celsius.
Always Use a Hard, Flat Surface
Never game with your TUF A15 on a blanket, pillow, or your lap. Those soft materials block the crucial intake vents on the bottom of the laptop, causing heat to build up instantly. Always place it on a hard desk or table.
For even better airflow, consider a laptop cooling pad. A good pad with fans that align with your laptop's own vents can lift it up and push extra air inside, often lowering temperatures by another 5-10 degrees. It's one of the best investments for long gaming sessions.
Manage Background Tasks and Power Plans
Hit Ctrl + Shift + Esc to open Task Manager. Sort by "CPU" and see if anything is using a high percentage when you're not gaming. Browser tabs, especially in Chrome, and apps like Discord can sometimes spike CPU usage.
Also, right-click the battery icon in your system tray and open Power Options. Make sure you're using the "Balanced" plan or an ASUS-specific plan instead of "High performance" for everyday use. The Windows High Performance plan keeps your CPU running fast all the time, which creates unnecessary heat.
Update Your BIOS and Drivers
ASUS periodically releases BIOS updates that can improve the fan curve and thermal management algorithms for your specific model. These updates are important. Go to the official ASUS support website, enter your TUF A15 model number, and download the latest BIOS and chipset drivers.
While you're there, also check for updates to your NVIDIA graphics drivers. Newer game-ready drivers often include optimizations that can improve efficiency and reduce GPU heat output. Keeping everything updated is a key part of thermal maintenance.
Optimize In-Game Graphics Settings
You don't always need to run every game on Ultra settings. High heat is often a sign your hardware is being pushed to its absolute limit. Try lowering a few demanding settings like shadows, anti-aliasing, or ambient occlusion.
Using a frame rate cap, either in the game's settings or through the NVIDIA Control Panel, can also work wonders. Capping your FPS to your monitor's refresh rate (like 144 FPS) stops your GPU from rendering hundreds of unnecessary frames, which significantly reduces its workload and heat.
Consider Undervolting the CPU and GPU
This is an advanced but highly effective technique. Using a tool like ThrottleStop for the CPU or MSI Afterburner for the GPU, you can slightly lower the voltage supplied to the chip. This reduces heat and power consumption without hurting performance, and can sometimes even improve it by preventing thermal throttling.
A modest CPU undervolt of -50mV to -80mV is a stable starting point for most TUF A15 models. For the GPU, a slight voltage curve adjustment in Afterburner can yield similar results. There are many good guides online specific to your laptop's processor generation.
Repaste the Thermal Compound
If your laptop is a couple of years old and still overheating after all the above steps, the factory-applied thermal paste between the CPU/GPU and the heatsink may have dried out. Replacing it with a high-quality paste like Arctic MX-6 or Thermal Grizzly Kryonaut can dramatically improve heat transfer.
This requires you to carefully open the laptop, remove the cooling assembly, clean off the old paste, and apply new paste. If you're not comfortable with disassembly, a local computer repair shop can handle this service. A fresh paste application is often the final solution for persistent overheating.
