Gaming laptop thermal throttling occurs when your CPU or GPU hits a temperature or power limit and drops clock speed to protect the hardware. Fix it by monitoring with HWiNFO64, undervolting with ThrottleStop (Intel) or Ryzen Master (AMD), adjusting fan curves via manufacturer software, and repasting when temps remain extreme after software tuning. This guide covers Intel and AMD gaming laptops equally.
Thermal throttling is the silent FPS killer. Your gaming laptop might have an Intel Core i9-13900HX or AMD Ryzen 7 7745HX on paper, but if it throttles within minutes of starting a game, you are getting mid-range performance from a premium chip. The fix is not difficult — it requires the right tools and the right understanding of your specific platform.
How to Confirm Your Laptop Is Thermal Throttling
Download and run HWiNFO64 in Sensors-only mode during a gaming session. In the Sensors view, look for the CPU column labeled Thermal Throttling — if it reads TRUE at any point while you are gaming, your CPU is actively pulling back clock speeds to manage heat. That single indicator is more reliable than any FPS counter or temperature readout alone.
A second signal is the clock speed pattern. Check the CPU clock speed in HWiNFO64 under load. If your laptop boosts to 4.5GHz in the first 30 seconds and then settles at 2.0GHz to 2.5GHz after two to three minutes, that sustained clock collapse is thermal throttling. Compare this against your CPU spec sheet: the sustained base clock should be reachable without throttling on a properly cooled system.
Also watch the PL1 and PL2 power limit values in HWiNFO64. PL2 is the short burst power limit, and PL1 is the sustained limit. If PL1 is set aggressively low by the manufacturer, common on thin-and-light gaming laptops, the CPU reaches it quickly and throttles even before hitting thermal limits. This is a power throttle rather than a temperature throttle, and the fix differs slightly from a pure thermal solution.
Fix for Intel Gaming Laptops: ThrottleStop Undervolting
ThrottleStop 9.6 is the standard tool for Intel gaming laptop thermal management. It allows you to apply a core voltage offset that reduces heat output without reducing performance, effectively letting your CPU run at the same clock speeds while generating less thermal energy. This is the fix for Acer Predator, ASUS ROG Intel models, MSI Titan, and Lenovo Legion Intel variants.
Open ThrottleStop and click the FIVR button. Under CPU Core, enable the voltage offset and start at -80mV. Save and run a 30-minute gaming session. If the system remains stable, increase to -100mV. Most Intel laptop CPUs tolerate -80mV to -120mV without instability; pushing beyond -120mV risks system crashes during heavy workloads. Apply the same offset to CPU Cache for maximum thermal benefit.
If your laptop throttles aggressively even at low temperatures, locate the BD PROCHOT checkbox in ThrottleStop and disable it. BD PROCHOT is a signal that triggers CPU throttling when the GPU gets hot, even if the CPU itself is running cool — a conservative factory setting that penalizes the CPU unfairly during GPU-heavy scenes. Disabling it allows the CPU to maintain full speed regardless of GPU thermals.
To make ThrottleStop settings persist across reboots, use Windows Task Scheduler to run ThrottleStop at startup with your saved .ini profile. This ensures undervolting is always active without manual intervention after each restart.
Fix for AMD Gaming Laptops: Ryzen Master and PPM Provisioning
AMD gaming laptops cannot use ThrottleStop — that tool is Intel-only. For laptops running Ryzen 7 7745HX, Ryzen 9 8845HS, Ryzen 9 7945HX, or similar Ryzen mobile CPUs, the correct tools are Ryzen Master and the manufacturer power management software. This is the gap that nearly every thermal throttling guide ignores, leaving AMD laptop owners without actionable steps.
On ASUS ROG and TUF AMD laptops, open Armory Crate and switch to Manual mode under the Fan and System configuration. Here you can set custom TDP values. For the Ryzen 7 7745HX, raising the long-duration power limit from the factory 45W to 55W or 60W (if cooling allows) can eliminate throttling without excessive temperature increase. Monitor temps in HWiNFO64 and keep CPU junction temperature below 95C.
On Lenovo Legion AMD laptops, open Lenovo Vantage and navigate to Power, then Thermal Mode, then Custom. Lenovo exposes fan speed and power limit controls here. Set the thermal profile to Performance mode as a baseline before making manual adjustments to individual power limits.
For deeper AMD control, Ryzen Master allows you to set TDP, scalar values, and frequency limits directly. Use the Creator or Game mode profiles as a starting point, then adjust the PPT (Package Power Tracking) value upward incrementally. On the 7745HX and 8845HS, setting PPT to 65W to 70W while running aggressive fan curves typically eliminates throttling in sustained workloads.
Custom Fan Curves by Manufacturer
Software undervolting and power tuning only solve part of the problem. If your fans are not spinning fast enough, the CPU and GPU will still hit thermal limits regardless of voltage adjustments. Every major gaming laptop brand exposes fan control through its companion software — set fans to maximum speed above 80C on both the CPU and GPU sensors.
ASUS ROG and TUF: Open Armory Crate, navigate to Fan Profile, and select Manual. Set a steep fan curve that hits maximum RPM at 80C. ASUS laptops with the MUX switch also benefit from enabling dGPU mode, which routes GPU output directly to the display and reduces GPU temperatures by eliminating iGPU processing overhead.
MSI gaming laptops: Use MSI Center and navigate to Fan Tuning. MSI exposes independent CPU and GPU fan controls. Set both to Advanced mode and configure a curve that maximizes airflow at high temperatures. The MSI Titan GT77 and Raider GE78 respond particularly well to aggressive fan curves combined with ThrottleStop undervolting.
Lenovo Legion: Open Lenovo Vantage, go to Power, then Thermal Mode, and select Performance. For maximum fan speed, enable the Performance mode toggle. Legion laptops also support a dedicated fan button on the keyboard that forces maximum fan speed instantly during intense gaming sessions.
Acer Predator: Open PredatorSense and navigate to Fan Speed. Set CPU and GPU fan speeds to Auto or Manual, then push manual curves to maximum at 80C. Acer Predator laptops with Turbo mode in PredatorSense activate maximum fan speed and remove power limits simultaneously for unrestricted performance.

Repasting: When Software Fixes Are Not Enough
If your laptop reaches 100C at near-idle temperatures or continues to throttle heavily after applying all software fixes, the thermal compound between the CPU die and heatsink has likely degraded. Most gaming laptops ship with low-grade compound that dries out within 18 to 24 months under heavy use. Replacing it is the most effective thermal intervention available and routinely drops peak temperatures by 10C to 20C.
For repasting, Thermal Grizzly Kryonaut is the standard recommendation for ceramic-based compound. It performs significantly better than factory paste and is safe on all laptop platforms. For Intel CPUs with a soldered heat spreader, common on HX-series chips like the Core i9-13900HX, Thermal Grizzly Conductonaut liquid metal offers even better conductivity, with drops of 15C to 25C reported on platforms like the Lenovo Legion 7i and ASUS ROG Strix.
Do not use liquid metal on AMD laptop APUs with a soldered die unless you have confirmed compatibility with your specific model. Liquid metal can cause electrical shorts if it spreads beyond the die surface, and some AMD mobile platforms have components positioned close enough to the CPU die to create risk. Ceramic paste like Kryonaut is the safe default for AMD repasting.
Before repasting, check whether your laptop warranty covers thermal maintenance. Lenovo Legion and ASUS ROG both officially sanction repasting under their gaming laptop care documentation. Razer and MSI are more restrictive, though repasting a laptop that is out of warranty is universally accepted in the gaming community as a standard maintenance task.
Frequently Asked Questions
How do I know if my gaming laptop is thermal throttling during games?
Open HWiNFO64 in Sensors-only mode and run it alongside your game. Look for the Thermal Throttling field in the CPU section — if it shows TRUE at any point, your CPU is throttling. A secondary sign is your CPU clock speed dropping from its boost frequency to near base clock after a few minutes of sustained gaming load, even when GPU utilization remains high.
Is undervolting a gaming laptop safe and does it void the warranty?
Undervolting reduces heat without reducing performance and is generally considered safe for Intel CPUs at offsets between -80mV and -120mV. Most manufacturers, including ASUS, Lenovo, and Acer, do not void warranties for software-level undervolting via ThrottleStop. Hardware modifications like repasting may affect warranty coverage depending on your region and specific brand policies.
How much FPS can I gain by fixing thermal throttling on a gaming laptop?
The improvement depends on how severely your laptop was throttling. In cases where the CPU dropped from 4.5GHz to 2.0GHz under load, fixing throttling can recover 20 to 40 percent CPU-bound performance. In GPU-limited scenarios the gains are smaller, typically 5 to 15 percent. The bigger improvement is consistency — eliminating the FPS drops that occur when throttling kicks in mid-session.

Can I fix AMD gaming laptop throttling with ThrottleStop?
No. ThrottleStop is an Intel-only tool that communicates with Intel-specific power management registers and does not work on AMD Ryzen mobile CPUs. For AMD gaming laptops, use Ryzen Master for TDP and frequency control, combined with your manufacturer companion app such as Armory Crate, Lenovo Vantage, or OMEN Gaming Hub for fan curve adjustments.
