ASUS TUF Gaming A15 AMD Ryzen 7 7745HX GPU Overheating Fix Windows 11

The GPU in your ASUS TUF Gaming A15 AMD Ryzen 7 7745HX is overheating during gaming – GPU temperature exceeds 90 degrees Celsius causing thermal throttle that reduces game performance, or the laptop shuts down unexpectedly from thermal protection. Fan mode settings, vent cleaning, and thermal management restore normal GPU temperatures on the TUF Gaming A15.

This guide covers Armoury Crate fan settings, thermal vent maintenance, and GPU power limit adjustment for the ASUS TUF Gaming A15 AMD Ryzen 7 7745HX in Windows 11.

“TUF Gaming A15 AMD GPU hit 95 degrees during gaming and throttled badly. Cleaned vents with compressed air – dust flew out like a storm. Temperatures dropped to 80 degrees immediately and performance stabilized. Regular cleaning is essential.” – Khairul, esports player from Kuantan

Why GPU Overheats on ASUS TUF Gaming A15

The ASUS TUF Gaming A15 AMD Ryzen 7 7745HX heatsink serves both the Ryzen 7 7745HX CPU and NVIDIA RTX GPU through a shared thermal system with multiple heat pipes. Dust accumulation in the heatsink fins reduces airflow through the cooling system – with just 30-40 percent of the fin area blocked by dust, GPU temperatures can rise 15-20 degrees Celsius above clean-heatsink baseline, pushing sustained gaming temperatures above the thermal throttle threshold. Thermal paste between the GPU die and heatsink contact plate also degrades over 18-24 months, increasing thermal resistance and GPU temperatures.

• Dust accumulation in heatsink fins blocking airflow – most common cause of GPU overheating
• Fan mode in Balanced instead of Performance/Turbo for gaming workloads
• Thermal paste between GPU die and heatsink degraded after 18-24 months of use
• Laptop on soft surface blocking bottom air intake reducing fresh air to heatsink

Fix 1 – Enable Turbo Fan Mode in Armoury Crate

Open ASUS Armoury Crate and find the fan profile selector. Switch from Balanced or Performance to Turbo mode. Turbo mode runs both fans at maximum RPM regardless of temperature, providing maximum airflow through the TUF Gaming A15 heatsink. GPU temperatures typically drop 5-10 degrees Celsius in Turbo vs Performance fan mode during sustained gaming load. Turbo mode is loud but provides the lowest GPU temperatures available without hardware modification. Use Turbo mode for competitive gaming sessions where performance is prioritized over acoustic comfort.

Fix 2 – Clean Thermal Vents with Compressed Air

Power off the TUF Gaming A15 completely. Hold a compressed air can upright and blow short bursts into the exhaust vents on the rear and side of the laptop. Hold the fan blades still with a toothpick or pin inserted through the vent grille during each blast to prevent the fans from spinning from the compressed air (spinning fans from compressed air can damage bearings). Repeat 4-5 times until no more dust exits the vents. Also blow compressed air into the bottom intake vents. After cleaning, restart and check GPU temperatures in GPU-Z during gaming – temperatures should decrease 10-20 degrees Celsius if significant dust was present in the heatsink fins.

Use Cooling Pad for Additional Airflow

Place the TUF Gaming A15 on a laptop cooling pad with active fans positioned under the bottom air intakes. A cooling pad that blows cool air upward into the laptop’s bottom intakes supplements the internal cooling system by increasing the temperature differential between intake air and GPU heatsink. Cooling pad effect is most pronounced in warm room environments (above 28 degrees Celsius ambient) where the GPU heatsink is receiving already-warm air through the intakes, reducing the effective thermal gradient for heat dissipation from the GPU die to ambient air.

Fix 3 – Reduce GPU TGP in Armoury Crate

If cleaning and Turbo fan mode do not bring GPU temperatures below 88 degrees Celsius during sustained gaming, open Armoury Crate and switch from Performance to Balanced mode. Balanced mode reduces the NVIDIA RTX TGP by 20-30W, which directly reduces heat generation by the GPU. The trade-off is slightly lower frame rates (typically 10-15 percent less) but significantly lower GPU temperature and elimination of thermal throttle. Balanced mode without throttle often delivers similar or higher actual in-game frame rates compared to Performance mode with throttle, because the GPU runs at consistent non-throttled clocks in Balanced rather than fluctuating clocks in throttling Performance mode.

Fix 4 – Repaste GPU Thermal Compound

If the TUF Gaming A15 is over 18 months old and thermal vent cleaning does not reduce GPU temperatures, thermal paste replacement is the next step. Power off and remove the bottom panel. Access the heatsink retaining screws (consult ASUS service manual for correct screw removal order). Remove the heatsink, clean old thermal paste from GPU die and heatsink contact plate with isopropyl alcohol and cotton swabs. Apply a pea-sized amount of quality thermal paste (Thermal Grizzly Kryonaut or similar) to the GPU die center. Reinstall heatsink and test. Fresh thermal paste typically reduces GPU temperatures 8-15 degrees Celsius on the TUF Gaming A15 after the original paste has dried and lost thermal conductivity.

Frequently Asked Questions

How do I fix GPU overheating on ASUS TUF Gaming A15 AMD Ryzen 7 7745HX?

Clean exhaust vents with compressed air (most effective), enable Turbo fan mode in Armoury Crate, use cooling pad, reduce GPU TGP to Balanced mode if temperatures remain above 90 degrees.

What is normal GPU temperature for ASUS TUF Gaming A15?

75-85 degrees Celsius in Performance mode under sustained gaming load. Above 90 degrees triggers throttle. Above 95 degrees indicates cooling problem requiring vent cleaning.

How do I turn on max fan speed on ASUS TUF Gaming A15?

Armoury Crate – Turbo fan mode. Maximum fan RPM regardless of temperature. Louder but 5-10 degrees Celsius cooler GPU vs Performance fan mode.

Does ASUS TUF Gaming A15 AMD Ryzen 7 7745HX support liquid metal thermal compound?

Not recommended for end users. Standard thermal paste replacement with Thermal Grizzly Kryonaut provides 8-15 degree improvement safely without liquid metal application risks.

Conclusion

ASUS TUF Gaming A15 AMD Ryzen 7 7745HX GPU overheating in Windows 11 is resolved primarily by cleaning the thermal exhaust vents with compressed air to remove dust buildup that reduces heatsink airflow. Armoury Crate Turbo fan mode maximizes cooling airflow for lowest possible GPU temperatures. Cooling pad supplemental airflow helps in warm environments. GPU TGP reduction from Performance to Balanced mode eliminates thermal throttle when cooling capacity is insufficient for maximum TGP at ambient temperatures above 28 degrees Celsius. Thermal paste replacement after 18 months restores original GPU-to-heatsink thermal conductivity.
