How to Check Your Laptop's Temperature (CPU, GPU, and BIOS Methods)

The fastest way to check your laptop's CPU temperature without installing anything is to restart and enter the BIOS/UEFI setup — most manufacturers show a live CPU temperature reading on the main or hardware-monitor screen. For an on-screen reading while Windows is running, install a free monitoring tool like HWiNFO64 or Libre Hardware Monitor — Windows itself doesn't show CPU temperature anywhere in the interface.

That last part surprises a lot of people. Task Manager's Performance tab can show GPU temperature (pulled from your graphics driver), but it has never displayed CPU temperature, including in the current version of Windows 11. CPU temperature only comes from on-die sensors that the OS doesn't expose on its own — you need firmware (BIOS/UEFI) or third-party software that reads those sensors directly.

Below are the methods that actually work in 2026, roughly in order of convenience.

Check CPU temperature in the BIOS/UEFI (no install required)

Every laptop's BIOS/UEFI can report CPU temperature without any software, because you're reading the sensor before Windows even loads.

1. Restart your laptop.
2. As soon as it starts powering back on, repeatedly tap the BIOS entry key — commonly F2, F10, Esc, or Del. It's usually shown briefly on the boot screen; if not, search "[your laptop model] BIOS key."
3. Look for a PC Health, Hardware Monitor, H/W Monitor, or similar tab. CPU temperature is usually listed there alongside fan speed.

Two caveats: the reading is idle-only (you're not running any software that loads the CPU), and BIOS menus vary by manufacturer, so some laptops bury or omit this screen entirely. Don't change any other BIOS settings while you're in there unless you know what they do.

Check CPU temperature in Windows with a free tool

HWiNFO64 — the most detailed option

HWiNFO64 is free for personal use and actively maintained (regular updates as of mid-2026). It reads CPU, GPU, motherboard, battery, and drive sensors, and its "Sensors" window is the closest thing to an enthusiast standard for this kind of monitoring. It's more detailed than most people need, but you can ignore everything except the CPU package temperature row.

Libre Hardware Monitor — free and open source

Libre Hardware Monitor is an actively maintained, open-source fork of the older Open Hardware Monitor project, which has been effectively abandoned since around 2020 and doesn't reliably read sensors on recent CPUs and GPUs. If you want an open-source tool with current hardware support, use Libre Hardware Monitor, not the original — it has hundreds of additional sensor definitions the old project never got.

Core Temp — simplest CPU-only view

Core Temp is free and focuses on CPU temperature per core, with an optional taskbar readout. The installer bundles optional third-party software offers during setup — uncheck any offers you don't want, or download the standalone ZIP version instead, which skips the installer step entirely.

HWMonitor — CPUID's lightweight option

HWMonitor from CPUID is another free, lightweight option showing current, minimum, and maximum temperatures and voltages per core.

NZXT CAM

NZXT CAM is free with no account required and is actively updated. It's built primarily for NZXT hardware but works as a general system monitor on any PC.

Vendor and OEM tools you may already have

If your laptop's CPU is unlocked or from a recent generation, you might already have a temperature readout built into a vendor app:

• AMD Ryzen Master — official monitoring/tuning tool for Ryzen CPUs.
• Intel XTU (Extreme Tuning Utility) — Intel's overclocking and monitoring tool. As of 2026 it's split into two branches: version 7.x for 14th Gen Core and older, and version 10.x for Core Ultra 200S ("Arrow Lake") and newer — grab the version that matches your CPU generation from Intel's download page.
• OEM apps many laptop owners already have installed: Lenovo Vantage, MyASUS, Armoury Crate (ASUS ROG), HP OMEN Gaming Hub, and Acer NitroSense all include a temperature or thermal readout in their dashboard.

Check temperature on a Mac

macOS has no built-in temperature display, so third-party tools fill the gap:

• Stats — free, open-source, actively developed menu-bar monitor that works on both Apple Silicon and Intel Macs and shows CPU/GPU temperature alongside load, memory, and network stats.
• TG Pro and iStat Menus — paid menu-bar utilities with more detailed sensor breakdowns and alerting.

If you're comfortable with Terminal, sudo powermetrics --samplers thermal shows the system's current thermal pressure level (e.g., "Nominal," "Moderate," "Heavy") on Apple Silicon Macs. It's a useful throttling indicator, but Apple Silicon doesn't expose the same raw System Management Controller (SMC) temperature values that Intel Macs did, so it won't give you a precise degree reading — for that, use one of the apps above.

Safe laptop temperature ranges

Take these as typical guidance, not hard limits — safe ranges vary by CPU model and how your laptop's manufacturer tuned its cooling:

• Idle: roughly 30–50°C
• Under sustained load (gaming, video export, compiling): roughly 70–85°C is typical for modern laptop CPUs
• 95–100°C sustained: at or near the throttle limit. Most CPUs have a maximum junction temperature (TjMax) around 100–105°C and will automatically throttle clock speed to stay under it — this is the chip protecting itself, not immediate damage.

Laptop CPUs run hotter than desktop CPUs by design — thinner chassis, smaller heatsinks, and less airflow mean manufacturers tune them to operate closer to their thermal limit. A gaming laptop hitting 90-95°C under full load with a fan spinning up is often working exactly as intended, not failing. GPU temperatures follow a similar range but typically throttle at a somewhat lower ceiling than the CPU.

What to do if your laptop is running hot

• Clean the intake and exhaust vents. Dust buildup on the fan and heatsink fins is the single most common cause of rising temperatures over time. Compressed air every few months helps.
• Use a hard, flat surface. Beds, couches, and blankets block the intake vents on the bottom of most laptops and can raise temperatures significantly.
• Check power/performance mode. Windows and most OEM apps (Lenovo Vantage, Armoury Crate, etc.) let you switch to a quieter, cooler performance profile, or adjust the fan curve to ramp up earlier.
• Consider a cooling pad. A pad with its own fans sits under the laptop and improves airflow. Check price on Amazon
• Undervolting can lower temperatures at the same performance level, but it's increasingly locked out on modern Intel laptop CPUs by the manufacturer or BIOS — check whether your model supports it before assuming this is an option.
• Repasting the thermal paste between the CPU die and heatsink is an effective fix for laptops several years old whose paste has dried out, but it usually means opening the chassis and voids warranty on many models — treat it as an advanced, last-resort step.

Frequently asked questions

Is 90°C bad for a laptop CPU? Not necessarily. Many laptop CPUs, especially in thin or gaming laptops under sustained heavy load, run in the high 80s to mid-90s°C as normal behavior — the chip is designed to operate there and will throttle automatically if it gets too close to its limit. It becomes a concern if you see 90°C+ during light tasks (browsing, idle) or if performance is visibly dropping (stuttering, slow response) alongside the high reading, which points to inadequate cooling rather than expected behavior under load.

Does Windows 11 show CPU temperature anywhere? No. Task Manager's Performance tab can show GPU temperature if your graphics driver reports it, but there's no CPU temperature reading anywhere in Windows 11's built-in interface. You need the BIOS/UEFI or a third-party tool.

Why is my laptop hot but the fan isn't running? Some laptops keep the fan off or at minimum speed until the CPU crosses a temperature threshold to stay quiet. If it's warm but not uncomfortably hot, this is often normal fan-curve behavior rather than a fault.

Can overheating damage my laptop? Modern CPUs throttle or shut down before reaching damaging temperatures, so a single hot session under load is unlikely to cause harm. Repeated sustained overheating over months or years, however, can accelerate wear on the battery, thermal paste, and other components, so it's worth investigating persistent high idle temperatures rather than ignoring them.

The final verdict

Windows and macOS don't give you a built-in CPU temperature reading, so your fastest no-install option is the BIOS/UEFI, and your best always-on option is a free tool like HWiNFO64 or Libre Hardware Monitor. If your laptop is consistently running hot, start with the basics — clean the vents, use a hard surface, check your power profile — before considering a cooling pad or a repaste.
