Best programs for monitoring CPU and GPU temps: quick picks
For most Windows gaming PCs, use HWiNFO for detailed sensor monitoring and logging, then add MSI Afterburner if you want an in-game overlay and alerts. If you prefer one simple app, try HWMonitor; for a clean dashboard with history, consider Libre Hardware Monitor. Your best choice depends on the sensors your hardware exposes and whether you need live readings, troubleshooting logs, or temperatures visible while gaming.

The figures below describe software features, not temperature accuracy. Displayed sensor count varies with your motherboard, processor, graphics card, firmware, and drivers. The listed CPU and GPU temperatures update in seconds, not as laboratory-grade measurements.
| Program | Cost | Logging | Alerts and overlays | Best fit |
|---|---|---|---|---|
| HWiNFO | Free for personal use | CSV logging; configurable polling interval, including 1-second sampling | Configurable sensor alerts; can share data with supported overlay tools | Broad sensor detail and troubleshooting |
| MSI Afterburner | Free | Monitoring history and on-screen display options | Customizable in-game overlay; configurable monitoring alerts | Gaming overlays and GPU-focused monitoring |
| HWMonitor | Free version available | Current, minimum, and maximum readings; fewer logging controls than HWiNFO | No built-in in-game overlay | Quick, uncomplicated checks |
| Libre Hardware Monitor | Free and open source | Sensor history and CSV logging | Dashboard-style monitoring; overlay options are more limited | Users who want an open-source sensor monitor |
| AMD Software: Adrenalin Edition | Free with supported AMD graphics hardware | Performance metrics and session monitoring | AMD metrics overlay and configurable performance displays | AMD GPU owners who want a vendor-supported option |
Feature availability can change between versions, and some readings require administrator access or compatible hardware. Check the current software documentation before relying on a particular alert, sensor, or integration.
Choose by situation, not by sensor count
| Your setup or goal | Good starting choice | Why |
|---|---|---|
| You want the most detail for diagnosing heat or fan behavior | HWiNFO | It exposes a wide range of available CPU, GPU, motherboard, and drive sensors, with configurable logging. |
| You mainly play games and want temperatures on screen | MSI Afterburner | Its overlay can show selected temperatures while a game is running. |
| You want a quick temperature check without a busy interface | HWMonitor | It presents current and recorded minimum/maximum values in a simple list. |
| You have an AMD graphics card and want a vendor tool | AMD Software: Adrenalin Edition | It combines supported GPU metrics with driver and graphics settings. |
| You use Linux or prefer open-source tools | Libre Hardware Monitor on supported Windows systems; Linux-native tools on Linux | Hardware sensor support is operating-system and device dependent. On Linux, tools such as lm-sensors and MangoHud may be a better fit. |
What matters in a CPU and GPU temperature monitor
Sensor support and compatibility
A monitor can only report what the hardware and its drivers make available. Modern CPUs may expose several temperature readings, such as a package temperature and individual core temperatures. Graphics cards may report a main GPU temperature as well as hotspot or memory-junction readings, but not every model exposes every sensor. Motherboard labels can also be unclear or show unused inputs. Treat implausible or unchanging values as a compatibility issue until verified, not as proof that a component is overheating.
Compatibility is especially important on laptops, prebuilt PCs, and newer hardware. Start with a current software version, install the relevant chipset and graphics drivers, and compare readings with the computer maker’s or GPU vendor’s own utility where possible. Avoid running several tools that poll low-level sensors at once: overlapping access can cause conflicts or confusing readings on some systems.
Logging and alerts
Logging is useful when a temperature spike happens only after 20 minutes of gaming or during a sustained export. A one-second interval produces 60 samples per minute; over a 30-minute session, that’s 1,800 samples per sensor. At a 10-second interval, the same session produces 180 samples. Use faster sampling when chasing brief spikes and slower sampling for long-term trends. More frequent polling can create larger files and slightly increase monitoring overhead.
Alerts are most useful when they are tied to a specific sensor and a sensible threshold. Don’t copy a single universal temperature limit: safe operating ranges differ by processor, graphics card, and sensor type. Check the component manufacturer’s specifications, and set an alert below the relevant limit so you have time to investigate. An alert is a warning aid, not a substitute for the system’s built-in thermal protections.
Overlays and everyday usability
An overlay is convenient for checking temperatures without leaving a game, but it needs to be configured deliberately. Show only the readings you need—typically CPU temperature, GPU temperature, and perhaps GPU hotspot—rather than filling the screen with dozens of metrics. Some games, anti-cheat systems, or graphics APIs may block overlays or cause conflicts. If an overlay disappears, test without it before changing game or driver settings.
Setup that produces useful readings
- Install one primary monitor. Choose HWiNFO for diagnostic depth or a vendor utility for a simpler first check. Download it from the developer or hardware manufacturer.
- Identify the right sensors. Note CPU package or core temperatures and the GPU’s main temperature. Add hotspot or memory readings only if your hardware exposes them and you know what they represent.
- Record a baseline. Observe the PC at idle, then during a repeatable workload such as the same game scene or a rendering task. Record the room conditions and workload so future comparisons are meaningful.
- Log a full session if a problem is intermittent. A 10-second interval is a practical starting point for a long session; switch to faster sampling if short-lived spikes matter. Stop logging when finished to avoid collecting unnecessary data.
- Add an overlay or alert only if needed. Configure a small overlay in Afterburner or use HWiNFO’s supported integrations, then verify the displayed sensor against the monitor’s main window.
Common ownership mistakes
Monitoring software is lightweight, but it still needs occasional upkeep: update it after major hardware or driver changes, review sensor labels, and remove old logs when they are no longer useful. Don’t compare a laptop under a quiet power profile with a desktop under an unrestricted performance profile and conclude that one has a cooling fault. Also avoid judging cooling from a brief idle reading; fan curves, room temperature, background tasks, and workload all affect the result.
If temperatures rise sharply, the first checks are often airflow obstruction, dust buildup, blocked laptop vents, and fan behavior. Shut down before cleaning, follow the manufacturer’s instructions, and don’t open a device if doing so could damage it or affect warranty coverage. Monitoring software can help narrow down when a problem occurs, but it cannot identify every cause by itself.
Bottom line
For a flexible all-around setup, choose HWiNFO for sensor coverage and logging, and add MSI Afterburner only if you need a gaming overlay. Pick HWMonitor for quick checks, or start with your graphics-card maker’s utility for a simpler vendor-supported view. The best program for monitoring CPU and graphics card GPU temperatures is the one that correctly reads your hardware, records the information you need, and stays out of the way the rest of the time.
