How to check PC temperatures in CS2 and what to do about overheating
How to see CPU and GPU temperatures while playing, which values are normal and how to fix the overheating that drops your FPS.
If FPS in CS2 is fine at first but drops after 10–20 minutes, a common cause is overheating. Hardware lowers its clocks to protect itself.
🔧 How to see temperatures
MSI Afterburner with RivaTuner — shows CPU and GPU temperatures in game.
HWiNFO — detailed monitoring of every sensor.
Task Manager → Performance shows the GPU temperature.
📌 What is normal
GPU under load: usually up to 80–85 °C.
CPU under load: most models up to 85–90 °C.
Higher values plus dropping FPS mean thermal throttling.
Exact limits depend on the model — check the manufacturer's site.
🧹 How to fix overheating
Clean the dust out of fans, heatsinks and filters.
Replace thermal paste if it is more than 2–3 years old.
Ensure airflow — do not push the case against a wall.
Use a cooling pad for laptops.
🎯 Quick fix
Cap your FPS (fps_max) slightly above your refresh rate — hardware works less hard and runs cooler.
⚠️ Tip
If temperatures suddenly rose after long trouble-free use, check that the fans are spinning.
