Nothing pulls you out of an immersive gaming session faster than a sudden shutdown, performance drop, or a scary overheating warning. Whether you’re on a high-end PC, a PlayStation 5, or a Steam Deck, heat is the enemy of every modern gaming rig. Newer games push hardware to its limits, often exposing cooling weaknesses you never knew you had. In this guide, we’ll walk you through the most common causes of overheating during gameplay and how to fix them, no matter what hardware you’re using.
General Overheating Causes and Quick Fixes
Before diving into device-specific solutions, let’s cover the fundamentals. Overheating almost always boils down to one of three things: inadequate cooling, dust buildup, or excessive ambient temperature. Make sure your gaming room isn’t too hot (ideally below 25°C or 77°F). Dust is the silent performance killer. Regularly blow out vents and fans with compressed air, and for PCs, clean intake filters monthly. Poor airflow is another major culprit. Ensure your PC case, PS5, or Steam Deck has ample clearance on all vented sides. Never place them inside an enclosed cabinet while gaming. Lastly, thermal paste degradation can cause spikes in temperature after a few years. If your device is older, a repaste may be in order.
PC Overheating: CPU and GPU
When your desktop or laptop CPU or GPU overheats during new games, it’s often because modern titles demand more power, pushing clocks higher and generating more heat. Chips like the Ryzen 5 7600X are designed to run hot, but they shouldn’t throttle or shut down. Here’s what to check.
Check CPU Cooler and Thermal Paste
A poorly mounted CPU cooler is the single most common cause of PC overheating. If you recently built your system, make sure the cooler is tightened evenly and that you removed any protective plastic film from the cold plate. For aging systems, dried-out thermal paste can’t transfer heat effectively. Remove the cooler, clean both surfaces with isopropyl alcohol, and apply a fresh pea-sized dot of quality paste before remounting. For the Ryzen 5 7600X, a high-performance air cooler or a 240mm AIO liquid cooler is recommended. The stock cooler (if any) might struggle under sustained gaming loads.
Optimize Airflow and Fan Curves
Check that your case fans are oriented correctly: front and bottom intake, rear and top exhaust. Use software like Fan Control or your motherboard’s BIOS to set more aggressive fan curves. GPU fans can be tuned with MSI Afterburner. Sometimes the default silent profile prioritizes low noise over cooling, which leads to overheating in demanding new games. Also, verify that your PC isn’t recycling hot air: keep it a few inches from walls and ensure the exhaust path is clear.
Adjust Power Settings or Undervolt
If cooling hardware is adequate but temperatures still spike, consider undervolting. Reducing voltage slightly while maintaining stability can dramatically lower heat output. For CPUs, this can be done via BIOS or Ryzen Master. For GPUs, MSI Afterburner’s curve editor works wonders. Additionally, in Windows, set your power plan to “Balanced” instead of “High Performance,” as the latter forces the CPU to run at maximum clocks constantly, generating unnecessary heat.
PS5 Overheating
The PlayStation 5 has a robust cooling system, but it’s not immune to overheating, especially with graphically intense games like EA Sports FC 25 or when the console is new and manufacturing quirks arise. Overheating manifests as on-screen alerts, sudden shutdowns, or performance throttling. Sometimes the console feels cool externally but still warns of overheating. This is because internal sensors detect excessive heat at the APU or SSD, even if the outer plastic shell stays cool.
Ensure Proper Ventilation
Place your PS5 in a well-ventilated spot with at least 10 cm (4 inches) of free space around all sides. Avoid carpeted floors, which block the air intakes at the front and sides. Standing the console vertically is fine, but ensure the stand is correctly attached so the bottom vents aren’t obstructed. If you have a PS5 Slim, note that its smaller chassis has less internal volume for airflow, so it’s even more sensitive to cramped placement.
Clean the Dust Catchers and Fan
Sony designed the PS5 with dedicated dust collection holes. Power off the console, unplug it, and remove the white faceplates. Use a vacuum with a soft brush attachment or compressed air to carefully clean the two dust catchers (under the fan) and the fan itself. Do this every few months, more often if you have pets or live in a dusty environment. A clogged heatsink is a common reason the PS5 overheats quickly, sometimes within minutes of launching a game.
Check for Game-Specific or Software Issues
Some users report overheating only with specific titles like EA Sports FC 25. This can happen if the game pushes the GPU or CPU unusually hard, perhaps due to poor optimization. Try lowering your console’s video output resolution to 1080p and turning off 120Hz mode in the PS5’s screen and video settings. Also, boot the PS5 in Safe Mode (hold power button for two beeps) and select”Clear Cache and Rebuild Database.” This can resolve software-related heat spikes without deleting your data.
When to Contact Support
If your PS5 Slim or standard PS5 overheats after just a few minutes of play despite being clean and well-ventilated, it might have a hardware defect. A faulty thermal interface material between the APU and heatsink, or a defective fan, could be to blame. Since the console is likely under warranty, contact Sony support for a repair or replacement. Do not attempt a DIY repaste on a new console, as it may void the warranty.
Steam Deck Overheating and Crashing
Valve’s Steam Deck is a compact powerhouse, but that portability comes with limited cooling capacity. Overheating can cause the system to throttle performance, freeze, or crash during demanding games. Here’s how to keep it cool.
Manage TDP and Frame Rate Limits
The Deck’s built-in performance settings are your best friend. Press the “…” button, go to the Performance tab, and enable “Advanced View.” Lower the TDP Limit to 10-12W for less demanding games, and set a GPU clock limit if you notice thermals climbing. Capping the frame rate to 40 FPS or 30 FPS can also drastically reduce heat output. Avoid playing with the charger plugged in if the battery is already hot, as charging adds extra heat.
Clean Vents and Repaste if Necessary
The fan intake is located on the back; keep it clear of obstructions. If you’ve had your Deck for over a year, dust can accumulate inside. Opening the Deck to clean the fan requires technical skill, but you can start by blowing compressed air into the intake and exhaust vents. If temperatures are still high (consistently above 90°C), a repaste of the APU might help. This is an advanced procedure and will void your warranty if not done carefully. Consider an RMA first if your Deck is still covered.
Monitor Thermals and RMA
Use the built-in performance overlay (level 4) to see CPU and GPU temperatures. If your Deck crashes consistently at a certain temperature threshold, it could be a hardware fault. Similarly, if the fan is excessively loud, rattling, or not spinning, it may need replacement. Contact Valve support for guidance. In many cases, a factory reset or a SteamOS update can resolve erratic fan behavior, but persistent overheating with crashes warrants a warranty claim.
