Is your temperature normal?

  • Below 45°C — cooler than 90% of submissions for this hardware. Excellent cooling.
  • Between 45°C and 50°C — within the typical range for this hardware.
  • Above 50°C — hotter than 90% of submissions. Worth investigating: thermal paste, cooler mount, dust, or case airflow.
  • Above 90°C — at or beyond the safe operating ceiling for this tier. Reduce load, check cooling, and consider professional inspection.

What's normal for this tier?

Mid-range CPUs are well within thermal headroom on stock or basic aftermarket coolers, usually 60–80°C under load. Anything consistently above 85°C warrants a cooling check.

Ambient room temperature affects readings. Average reported ambient: 23.9°C.

Frequently asked questions

What is a normal temperature for the Intel Core i5-6600K?

Based on 3 community submissions, the Intel Core i5-6600K runs at an average idle temperature of 38°C and an average load temperature of 47.3°C. Anything between 45°C and 50°C under load is within the typical range for this hardware.

Is 47.3°C too hot for the Intel Core i5-6600K?

The safe operating ceiling for mid-range CPUs like the Intel Core i5-6600K is around 90°C under sustained load. 47.3°C is within the safe operating range. If you're exceeding 90°C, check thermal paste, cooler mounting, dust buildup, and case airflow.

What is the best cooler for the Intel Core i5-6600K?

For a 70W mid-range CPU like the Intel Core i5-6600K, a quality 240mm AIO or a high-end dual-tower air cooler (Noctua NH-D15, Thermalright Phantom Spirit) is generally sufficient to keep load temperatures well within safe limits. Higher TDP variants (overclocked or PBO-enabled) benefit from 360mm AIO cooling.
