Your fan is spinning fast, or the bottom of your laptop is hot to the touch, and you need to know the actual temperature to decide if something is wrong. This page gives you the exact numbers, the software paths, and the quick interpretation guide.
In short: Use free monitoring software like HWMonitor to read real-time CPU and GPU temperatures in Windows. For a baseline idle check, restart into BIOS/UEFI to see the hardware sensor directly. Compare your numbers to the safe load range of 70-85C for most modern processors.

Gives you a permanent, glanceable temperature display on your desktop without needing to open a window.
Replaces dried-out old compound under the CPU to restore proper heat transfer and lower operating temperatures.
What you need to read your laptop temperature
You do not need expensive hardware to monitor heat. Most users can rely on free software already available on their system or easily installed from the developer’s site. If that sounds like your bench, read up on reset pc keep files next.
- Windows 10 or 11: For the software methods described here.
- Free monitoring tool: HWMonitor, Core Temp, or MSI Afterburner.
- Brightness slider: Check that your screen brightness is not maxed out, as high brightness generates extra heat.
For users who want a constant visual reference, a small USB monitor is a practical alternative to juggling software windows. It keeps the data in your peripheral vision while you work.
Always download monitoring software directly from the official developer page to avoid bundled adware.
This monitor attaches to your USB port and displays live CPU and system temperatures on a small screen, removing the need to check software repeatedly.

How to read temps in Windows with free software
Third-party tools are the most accurate way to see live temperatures. HWMonitor is the standard recommendation because it is lightweight, free, and shows minimum, current, and maximum values.
- Download and install HWMonitor from the CPUID website.
- Open the program. The main window lists all detected sensors.
- Look under the Intel Core i9 / AMD Ryzen section for the CPU core temperatures.
- Check the NVIDIA / AMD section for GPU temperatures.
- Run a heavy task (like a game or video edit) and watch the Max column to see peak heat.
MSI Afterburner is better if you game. It includes an On-Screen Display (OSD) that overlays the temperature directly on your screen during gameplay.
How to check idle temperature in BIOS/UEFI
The BIOS is the cleanest way to check a baseline temperature without any operating system overhead. This is vital for spotting hardware cooling failures.
- Restart your laptop.
- Press the BIOS key repeatedly during the boot screen. Common keys are F2, Del, F10, or F12.
- Navigate to the Hardware Monitor, PC Health Status, or System Status page.
- Read the CPU Temperature value.
On HP laptops, such as a 2019 model, this section is often labeled System Status or BIOS Health in the bottom of the screen. On MacBooks, you cannot check BIOS; use the terminal command powermetrics or a tool like iStat Menus. We cover encrypt laptop storage in a guide of its own.
If your laptop shows 50C or higher in the BIOS while sitting idle, your cooling system is failing or blocked.
Pro tip: Do not run stress tests in the BIOS. It only shows idle heat. To check load heat, boot into Windows and use HWMonitor.
What are safe temperature ranges for laptop CPUs and GPUs?
Numbers mean nothing without context. A temperature that is dangerous for a thin laptop might be normal for a thick gaming rig. Use this table as a guideline for a standard 15-inch Windows laptop under load.
| Component | Normal (Load) | Concerning | Throttle/Danger |
|---|---|---|---|
| CPU (Intel/AMD) | 70C – 85C | 86C – 95C | 95C – 100C+ |
| GPU (NVIDIA/AMD) | 70C – 83C | 84C – 90C | 90C+ |
| Idle CPU | 30C – 45C | 46C – 55C | 55C+ |
Check your specific processor’s TJMax (Thermal Junction Maximum) on the manufacturer’s spec sheet for the exact shutdown point.
If your laptop is idling above 50C, or throttling (losing performance) at 90C, you need to fix the cooling system immediately.
How to fix high temperatures after you read them
Reading the temperature is only half the job. If the numbers are in the ‘Concerning’ column, take these steps in order. The other half of this decision is viewing the current health of the cell.
- Move the laptop: Place it on a hard, flat surface. Never use a bed or couch, which blocks the air intakes.
- Check the vents: Look at the side and rear vents. Use compressed air to blow out dust if you see buildup.
- Update the BIOS: Check your manufacturer’s support page. Newer BIOS versions often include improved fan curves that spin the fans faster when hot.
- Apply new thermal paste: If the laptop is over 3 years old, the old paste may have dried. Reapplying fresh compound can drop temperatures by 10-15C.
A fresh sheet of high-conductivity thermal paste is a permanent fix for older machines where heat has stopped transferring efficiently to the heatsink.
This 4-gram tube of high-conductivity paste is sized for one laptop CPU and one GPU, letting you re-service the cooling system directly.

Common mistakes when checking your laptop's temp
- Mistake: Only checking idle temps. Instead: Run a CPU stress test (like Prime95 or Cinebench) while monitoring to see peak heat.
- Mistake: Ignoring the battery temp. Instead: In HWMonitor, check the battery sensor. A battery above 45C is overheating and should not be charged.
- Mistake: Using the wrong fan settings. Instead: Use your manufacturer’s utility (like Lenovo Vantage or HP Command Center) to set the fan to ‘Maximum Performance’ if the CPU is hitting 95C.
- Mistake: Assuming a fan failure. Instead: If the fan is not spinning, check if it is on ‘Silent’ mode. Many laptops stop the fan below 50C to save battery.
The bottom line
Start with a free tool like HWMonitor to get your baseline and load numbers. If your idle temp is above 50C or your load temp hits 95C, your cooling system is failing. For most users who just need to keep an eye on the heat, an external monitor is the easiest daily tool.

Frequently asked questions
How do I check the temperature on a 2019 HP laptop?
Restart the HP laptop and press the Esc key, then F10 to enter the BIOS. Look for the ‘System Status’ or ‘BIOS Health’ section at the bottom of the screen. It lists the CPU temperature in Celsius. For a live reading while working, install HWMonitor in Windows.
What is a normal temperature for a laptop CPU?
A normal idle temperature is between 30C and 45C. Under heavy load, like gaming or video editing, a CPU running between 70C and 85C is standard. Consistently staying above 90C is a sign of a cooling problem.
Can high temperatures permanently damage my laptop?
Yes. Modern processors are designed to throttle (slow down) to protect themselves from immediate damage. However, chronically running in the 90C+ range degrades the thermal paste and stresses the solder joints, leading to a shorter component lifespan and potential performance loss over years.
Is it normal for my laptop to get hot near the vents?
Yes, the area around the exhaust vents will be the hottest part of the case and can feel warm even at normal operating temperatures. If the entire bottom panel or the keyboard area is too hot to touch for more than a few minutes, your internal cooling is not moving heat away from the CPU fast enough.
