How to Check Your PC's Temperature with Free Software
HWMonitor for the one-minute check, HWiNFO for deeper diagnostics — plus a reference table of normal CPU and GPU temperatures at idle and under load.
Before suspecting overheating from indirect symptoms, checking it directly with free software takes just a minute.
HWMonitor (the simplest)
Free, no complicated installation — it shows CPU, GPU and disk temperatures in real time, with minimum/maximum values for the current session.
HWiNFO (more detailed)
For anyone wanting to go deeper — extra sensors, more detailed history, useful when diagnosing something specific like spikes under load.
What temperatures are normal?
| Component | Idle | Under load |
|---|---|---|
| CPU | 30-45°C | 60-80°C (normal), 85°C+ (watch) |
| GPU | 30-45°C | 65-83°C (normal depending on model) |
These ranges are indicative — every processor or graphics card model has its own specific safety limit (check the manufacturer's spec sheet for the exact value for your particular component).
Tip: monitor the temperature while doing something demanding (a game, a stress test) to see behaviour under real load, not just at idle — load is where genuine cooling problems show up.
Frequently asked questions
What is the difference between HWMonitor and HWiNFO?
HWMonitor is simpler and more direct for a quick check. HWiNFO offers more detailed sensors and history, useful for more specific diagnostics such as spikes under load.
What is the maximum safe temperature for my processor?
It varies by exact model — check the manufacturer's spec sheet for your component's specific limit, since general ranges are only indicative.
