Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsIf you’re seeing a “Helldivers 2 high CPU temp” warning, throttling, crashes, or a PC that shuts down during play, first identify which symptom is happening and measure your processor under load. A game closing is not the same as Windows crashing or the whole computer powering off, and none of those symptoms alone proves that Helldivers 2 caused overheating. Check readings against the limit for your exact CPU model, then troubleshoot cooling and the game separately.
First, identify what is actually failing
“Helldivers 2 overheating my CPU” is a useful description of what you suspect, but a crash during play does not establish overheating as the cause. Note what happens when the problem occurs:
As an Amazon Associate I earn from qualifying purchases.
- Only the game closes: Record whether it returns to the desktop and whether Windows displays an error.
- Windows crashes or reports a hardware error: Record the message or stop code rather than treating it as a game-only crash.
- The whole PC shuts down: Note whether it powers off, restarts, or requires a manual restart.
Record your CPU model, CPU temperature and clock speed during play, and whether monitoring indicates throttling. Also note whether the same behavior occurs in other demanding workloads. These details help distinguish possible causes; they do not, by themselves, diagnose a fault.
Check CPU temperature against your processor’s limit
Monitor CPU temperature and clock speed while reproducing the issue. Compare the reading with the temperature limit specified for your exact processor model, rather than applying a universal cutoff: limits vary by manufacturer and model. Steam notes that monitoring may not show a temperature above a processor’s limit because modern CPUs can slow themselves to avoid overheating. Steam’s hardware overheating guidance explains this behavior.

- Ultra-Portable: Slim, portable, and light weight allowing you to protect your investment wherever you go
- Ergonomic Comfort: Doubles as an ergonomic stand with two adjustable height settings
- Optimized for Laptop Carrying: The metal mesh provides your laptop with a stable laptop carrying surface
- Ultra-Quiet Fans: Three ultra-quiet fans create a noise-free environment for you
- Extra Usb Ports: Extra USB port and power switch design allows for connecting more USB devices. Warm Tips: The packaged cable is USB to USB connection. Type C connection devices need to prepare an Type C to USB adapter
A high reading alone is not enough to establish why the game crashed. Look at temperature and clock behavior together, and note whether performance drops or throttling appears as the temperature rises. The available official guidance does not establish a Helldivers 2-specific safe CPU temperature or prove that the game itself causes thermal crashes.
If readings point to overheating, inspect cooling and airflow
With the PC powered down, check that the cooling system works and the computer has unobstructed access to cool air. Steam identifies dust buildup, blocked vents, and poor fresh-air access as possible cooling problems; it also lists better ventilation and a better heat sink among possible hardware fixes. See Steam’s overheating troubleshooting guidance.
Rank #2
- Whisper-Quiet Operation: Enjoy a noise-free and interference-free environment with super quiet fans, allowing you to focus on your work or entertainment without distractions.
- Enhanced Cooling Performance: The laptop cooling pad features 5 built-in fans (big fan: 4.72-inch, small fans: 2.76-inch), all with blue LEDs. 2 On/Off switches enable simultaneous control of all 5 fans and LEDs. Simply press the switch to select 1 fan working, 4 fans working, or all 5 working together.
- Dual USB Hub: With a built-in dual USB hub, the laptop fan enables you to connect additional USB devices to your laptop, providing extra connectivity options for your peripherals. Warm tips: The packaged cable is a USB-to-USB connection. Type C connection devices require a Type C to USB adapter.
- Ergonomic Design: The laptop cooling stand also serves as an ergonomic stand, offering 6 adjustable height settings that enable you to customize the angle for optimal comfort during gaming, movie watching, or working for extended periods. Ideal gift for both the back-to-school season and Father's Day.
- Secure and Universal Compatibility: Designed with 2 stoppers on the front surface, this laptop cooler prevents laptops from slipping and keeps 12-17 inch laptops—including Apple Macbook Pro Air, HP, Alienware, Dell, ASUS, and more—cool and secure during use.
- Check that vents are not blocked by a wall, desk surface, or other objects.
- Inspect fans and heat sinks for visible dust or anything preventing airflow.
- Check that fans operate when the PC is under load.
- Consider whether the PC’s placement allows it to draw in fresh air and exhaust warm air.
Do not assume that replacing a cooler or applying thermal paste will solve the issue without confirming a cooling problem. If inspection indicates that a different CPU cooler is needed, verify compatibility with your CPU socket, case height or radiator clearance, cooling capacity, noise expectations, and installation constraints before choosing one.

Follow Arrowhead’s Helldivers 2 troubleshooting steps
Once you have recorded the symptoms and checked for signs of overheating, try Arrowhead’s game-specific steps. Its General Tech troubleshooting tips, updated September 1, 2026, recommend the following:

- 9 Super Cooling Fans: The 9-core laptop cooling pad can efficiently cool your laptop down, this laptop cooler has the air vent in the top and bottom of the case, you can set different modes for the cooling fans.
- Ergonomic comfort: The gaming laptop cooling pad provides 8 heights adjustment to choose.You can adjust the suitable angle by your needs to relieve the fatigue of the back and neck effectively.
- LCD Display: The LCD of cooler pad readout shows your current fan speed.simple and intuitive.you can easily control the RGB lights and fan speed by touching the buttons.
- 10 RGB Light Modes: The RGB lights of the cooling laptop pad are pretty and it has many lighting options which can get you cool game atmosphere.you can press the botton 2-3 seconds to turn on/off the light.
- Whisper Quiet: The 9 fans of the laptop cooling stand are all added with capacitor components to reduce working noise. the gaming laptop cooler is almost quiet enough not to notice even on max setting.
- Check the minimum requirements. Compare your PC’s specifications with the game’s current Steam listing. The listing retrieved October 7, 2026 names an Intel Core i7-4790K or AMD Ryzen 5 1500X and 8 GB RAM as minimums; it names an Intel Core i7-9700K or AMD Ryzen 7 3700X and 16 GB RAM as recommended. Requirements can change, so check the live HELLDIVERS 2 Steam listing.
- Update relevant PC drivers. Arrowhead specifically calls out motherboard and GPU drivers. Use the appropriate source for your hardware.
- Verify the game files in Steam. Open Steam Library > game Properties > Installed Files > Verify file integrity, then let Steam complete the check.
- Clear the Arrowhead AppData folder contents. Open Windows Run, enter
%appdata%, and locate the Arrowhead folder. Clear its contents as Arrowhead instructs; take care not to delete unrelated folders. - Try Async Compute both ways. Toggle the setting on or off and check whether behavior changes. Arrowhead says the effect depends on the hardware, so there is no single setting that applies to every PC.
- Consider a full uninstall and reinstall. Arrowhead suggests this if specifications and drivers are fine but the issue remains.
If these steps do not resolve the game problem, Arrowhead directs players to contact its Player Support team. Include the symptom type, CPU model, temperature and clock readings, and whether other demanding workloads trigger the issue.

Steam’s guidance concerns PC hardware overheating: measure temperature, compare it with the processor’s model-specific limit, and inspect cooling and airflow. Arrowhead’s guidance concerns Helldivers 2 technical problems: check requirements, drivers and game files, clear the game’s AppData contents, test Async Compute, and reinstall if appropriate. A crash can warrant both checks, but one track does not prove the cause addressed by the other.
