Confirm correct thermal paste application: The application method may vary, so refer to a thermal paste application guide.







Check CPU Temperature





Enter BIOS after booting (press F2 or DEL repeatedly during startup) to check the CPU temperature.



Use third-party software like CPU-Z or other monitoring tools to check the CPU's idle temperature (a normal idle temperature should be below 45°C).



Monitoring Tools



If the CPU cooler is not installed properly, it can lead to overheating, automatic shutdowns, throttling, and other issues. By checking the mounting clips, testing stability, verifying thermal paste application, and monitoring temperatures, you can ensure that the cooler is correctly installed and keep your computer running stably!

Few things are more frustrating than watching your FPS suddenly dip while you are in the middle of a game. Your system seems fine, temps look normal, but the frame rate just drops out of nowhere. These unexpected FPS drops are extremely common, and there are several real reasons behind them.

High Temperatures Causing Thermal Throttling

The number-one cause of sudden FPS drops is excessive heat. When your CPU or GPU gets too hot, it automatically reduces its clock speed to protect itself, leading to instant performance loss.

, featuring louver side panel on PSU Chamber)

Running out of VRAM can cause instant FPS drops. When VRAM is full, the GPU is forced to offload data to system RAM, which is much slower.

Sometimes your game is not the problem. Windows or other apps may be taking CPU, GPU, or RAM in the background (e.g., Chrome tabs, Windows Update).

Power Supply Issues (Insufficient or Unstable Power)

This is an often overlooked cause. If your PSU cannot handle sudden power spikes (transients) from a modern GPU, your system may throttle or crash.

Insufficient RAM or Single-Channel Memory

Your FPS may drop if your system is running out of RAM or if it is running at low speed.

Modern games stream assets constantly. If you install games on a slow HDD, you will notice stuttering when moving to new areas.

Even the best hardware will throttle if it's choked by dust. Dust acts as an insulator, trapping heat inside heatsinks.

Conclusion: Stabilize Your Framerates with darkFlash

. While software tweaks can help, the ultimate fix is often ensuring your hardware has the environment it needs to perform. Whether you need better airflow, powerful liquid cooling, or a reliable power supply, 

darkFlash has the gear to keep your frames high and your temps low.

Typical throttle temperatures





CPU: around 90°C and above



GPU: 80–90°C depending on the model

Fixes





Improve Case Airflow: If your case feels like an oven, your components can't breathe. Consider upgrading to a high-airflow case like the darkFlash DY460 which features louvered side panels designed to maximize cold air intake.



(darkFlash DY460 ATX PC Case, featuring louver side panel on PSU Chamber)







Upgrade Your Cooler: Stock coolers often struggle with modern gaming loads. Switching to a darkFlash AIO Liquid Cooler (like the DE360/240 or DO360/240 Liquid Cooler) can drop temps significantly and keep boost clocks stable.



(darkFlash DE360 Liquid CPU Cooler)







Check Your Fans: Ensure you have positive or neutral air pressure. Adding high-performance darkFlash RGB fans not only looks great but ensures heat is actively pushed out of the chassis.

VRAM (Graphics Memory) Is Full

Running out of VRAM can cause instant FPS drops. When VRAM is full, the GPU is forced to offload data to system RAM, which is much slower.



Fixes





Lower texture quality in game settings.



Turn off demanding effects like Ray Tracing if your card struggles.



Pro Tip: A well-cooled GPU boosts higher and handles loads better. Ensure your case has bottom or front fans directing air straight to the GPU.





Background Programs Eating Resources

Sometimes your game is not the problem. Windows or other apps may be taking CPU, GPU, or RAM in the background (e.g., Chrome tabs, Windows Update).



Fixes





Use "Exclusive Fullscreen" mode in games.



Turn on Windows Game Mode.



Check Task Manager for sudden spikes.

Power Supply Issues (Insufficient or Unstable Power)

This is an often overlooked cause. If your PSU cannot handle sudden power spikes (transients) from a modern GPU, your system may throttle or crash.



Symptoms





Sharp FPS drops during explosions or intense scenes.



GPU usage fluctuating wildly.

Fixes





Ensure Stability: Never skimp on your power supply unit. A high-quality PSU provides stable voltage even during load spikes.



Upgrade Capacity: If you are running a high-end card (like an RTX 5080) on an old 600W unit, it's time to upgrade to a darkFlash High-Wattage PSU to ensure your system gets the clean power it needs.



(darkFlash PMT Power Supply, Cybenetics platinum certified)



Insufficient RAM or Single-Channel Memory

Your FPS may drop if your system is running out of RAM or if it is running at low speed.



Fixes





Enable XMP / EXPO in BIOS.



Ensure you are using dual-channel configurations (two sticks are better than one).





Slow Storage Causing Loading Stalls

Modern games stream assets constantly. If you install games on a slow HDD, you will notice stuttering when moving to new areas.



Fixes





Always install AAA games on an NVMe SSD.





Dust Buildup & Maintenance

Even the best hardware will throttle if it's choked by dust. Dust acts as an insulator, trapping heat inside heatsinks.



Fixes





Regular Cleaning: Clean your PC every 3-6 months.



Use Dust Filters: This is why most of darkFlash cases come equipped with easy-to-remove dust filters. They catch the dust before it hits your components, making cleaning as easy as peeling off the filter and wiping it down.
