The problem
Temperature tools give you numbers, not answers
Your laptop is roasting and the fan is screaming. You open a monitor and get 200 rows of sensors, none of which says what's wrong or what to do.
A wall of raw numbers
Hundreds of sensor rows with cryptic names. Is 85 degrees fine? Which line even is the CPU? You're left to guess.
Hot, but no idea why
The fans spin up while you're only browsing. Something is working the processor hard, and nothing tells you which app it is.
Silent slowdowns
A hot CPU quietly slows itself down to cool off. Games stutter and exports crawl, and nothing on screen explains it.
Drivers your antivirus flags
Older monitoring tools still rely on a kernel driver that Microsoft Defender now flags as a hack tool.
Offers and upsells
Installer offers, upgrade nags and accounts you never asked for, just to read a temperature.
No warning until it shuts down
Without an alert, the first sign of a dead fan or a clogged vent is a sudden shutdown in the middle of your work.
Vow Temperature Monitor fixes all of it.
How it works
Open. Check. Cool it down.
The verdict is on screen before you've read a single number, and the cause is one click away.
- 01
Open it: the verdict comes first
"Running cool", "Running hot" or "Hot enough to slow down" is the first line you see, with CPU, GPU, drive and fan readings underneath, each with its own graph.
Running cool: the verdict first, then CPU, GPU, drive and fans - 02
Press What's heating my PC?
Keep working, or start the game that makes it hot. After 15 seconds the apps causing the heat are ranked, with their CPU and GPU use and an estimate of the watts.
Scan for 15 seconds to see which apps heat your PC - 03
Let it keep watch
Close the window and the live temperature stays in the tray, coloured by heat. Overheating warnings are always on, and Unlimited adds your own alerts.

Features
Everything your PC's sensors know, in words you can use
For hot laptops, stuttering games and anyone who wants to know their PC is running safely.
An answer, not a spreadsheet
A plain-language verdict with practical tips, such as cleaning the vents or capping a game's frame rate.
Heat Finder
Ranks apps by their share of the heat: CPU and GPU use weighted by each part's power. Lower an app's priority or end it from the list.
Throttling caught and explained
See when the CPU is held back by heat or by a power limit, explained in words instead of a raw flag.
One-click cooling check
A 30-second to 2-minute load test that rates your cooling, and stops by itself if the CPU reaches 95 degrees.
Every sensor, when you want it
CPU, graphics cards, drives (SMART and NVMe), motherboard, battery, PSU, coolers and memory, with min, max and average.
Live temperature in the tray
The tray icon shows the temperature as a number, coloured by heat. Add a small always-on-top desktop widget if you like.
Alerts that fit how you work
Six ready-made rules for heat, throttling, a stopped fan or a long high load: a notification, a sound or a command of your choice.
History logs
Temperatures, fans, loads and power logged every 2 to 60 seconds in daily CSV files, with 6-hour to 30-day graphs and peaks.
Fan control with safety built in
Automatic, fixed or curve modes where the hardware allows. Never below your floor, full speed at critical heat, firmware back in charge on exit.
No flagged drivers
No WinRing0. For CPU readings it offers the signed PawnIO driver, downloaded from the official release and checked, only when you click.
Light & dark theme
Easy on the eyes, day or night.
Temperature Monitor comes with a crisp light theme and a calm dark theme. Switch with one click, or let it follow your Windows setting by itself. It remembers your choice.
- LightClear and bright for daytime and busy offices
- DarkGentle on tired eyes late at night
- Follow WindowsChanges by itself when your PC does

| Cooling test | One click, stops at 95 degrees | A separate stress tool |

Step-by-step guide
How to check your CPU and GPU temperature on Windows
From "why is my PC so hot?" to the answer and a fix, in a few minutes.
Step 1: get it freeInstall Vow Temperature Monitor free
Download it from this page and run the installer. It installs for your user only and needs no administrator rights or account.
Read the verdict
The first line says whether the PC is running cool, running hot or hot enough to slow down. Graphics cards, loads and clocks show within a second.
Turn on every sensor
Click Show every sensor in the orange banner. Windows asks for administrator rights once, which unlocks CPU, drive and motherboard readings.
Find what's heating your PC
Press What's heating my PC? (Ctrl+Enter) and keep using the PC, or start the game that makes it hot. After 15 seconds you get the ranked list of apps.
Act on it, then keep watch
Follow the tips, lower a busy app's priority or end it, and run the cooling check. Close the window and the tray keeps showing the live temperature.

FAQ
Questions about Temperature Monitor
Is Vow Temperature Monitor free?
Yes. Live temperatures, fan speeds, loads and clocks have no time limit, along with the verdict, throttling detection, the cooling check, the tray icon, the widget, overheating warnings and 3 Heat Finder scans a day. Unlimited, a one-time $4.95 USD payment, adds alerts, history logs, the live Heat Finder and fan control.
Why can't I see my CPU temperature?
Windows only lets programs read the CPU, drives and motherboard with administrator rights. Click Show every sensor and Windows asks once. The CPU and motherboard also need the free PawnIO driver: the app downloads the official signed setup, checks it, and Windows asks your permission first.
How does Heat Finder know which app is heating my PC?
It samples every app's processor and graphics use for 15 seconds and weights each by how much power that part draws. The result is a ranked list with each app's share of the heat, its CPU and GPU use and an estimate of the watts it costs.
What is thermal throttling?
When a processor gets too hot it slows itself down to cool off, which makes games stutter and work take longer. The app reads Windows' own performance-limit counters, tells you whether heat or a power limit is the cause, and suggests what to do.
Is fan control safe?
Fans are never set below the hardware's minimum or your floor (20% by default), and any part at its critical temperature gets full speed. If a reading goes missing, or the app exits or crashes, the firmware takes the fans back. Fan control works where the hardware allows it: GPU fans, many motherboard headers and some coolers.
How is it different from HWiNFO, HWMonitor or Core Temp?
You get an answer instead of a list of numbers: a verdict in plain words, the link from heat to the apps causing it, throttling explained, a one-click cooling check and a tray icon that shows the live temperature. It uses no WinRing0 driver, and asks for administrator rights only when you want every sensor.
Does it keep running when I close the window?
Yes, it keeps watching from the tray, where the icon shows the live temperature coloured by heat. Starting with Windows is optional. To stop it completely, right-click the tray icon and choose Exit.
Is it safe to install?
Yes. It is made and published by XTO Pty Ltd, an Australian company. There are no ads, no bundled software and no account, nothing is uploaded, it installs without administrator rights, and it uninstalls cleanly from Windows Settings.
