When Your PC Runs Too Hot
Overheating is one of the most common PC problems we see. It causes performance drops, crashes, and can shorten component life. Here's how to diagnose and fix thermal issues.
Signs of Overheating
Watch for these symptoms:
- Games suddenly dropping FPS
- Random shutdowns during gaming
- Loud fan noise
- Computer feeling very hot
- Blue screens during intensive tasks

Normal Temperature Ranges:
| Component | Idle | Load | Danger Zone |
|-----------|------|------|-------------|
| CPU | 30-40C | 60-80C | >90C |
| GPU | 30-45C | 65-85C | >95C |
Common Causes and Solutions
#### 1. Dust Buildup
The #1 cause of overheating.
Fix:
1. Power off and unplug
2. Open case
3. Use compressed air (short bursts)
4. Clean intake/exhaust areas
5. Clean CPU heatsink fins
Clean every 3-6 months, more if you have pets.
#### 2. Poor Airflow
Check your fan configuration:
- Front fans: Intake (pulling air in)
- Rear/top fans: Exhaust (pushing air out)
- Cable management: Keep cables out of airflow paths
#### 3. Old Thermal Paste
CPU thermal paste degrades over time.
Signs you need repaste:
- CPU runs hotter than it used to
- Paste is 3+ years old
- You removed the cooler for any reason
#### 4. Inadequate Cooling
Stock coolers are fine but basic. Upgrades that help:
- CPU: Tower cooler ($30-50) or AIO ($80-150)
- Case fans: More airflow ($10-20 each)
- GPU: Aftermarket cooler or more case airflow
#### 5. Ambient Temperature
Your room matters:
- AC during summer gaming sessions
- Don't game in direct sunlight
- Ensure adequate space around PC
