Taskvane shows what Task Manager does, plus the things it leaves out: CPU and GPU temperatures, power draw in watts and battery health. It's free, open source, and light enough to leave running.
Task Manager can't tell you. Drag the marker to see what your CPU temperature means and how Taskvane would show it.
Typical while gaming or exporting video. Fans spin up, and that's expected.
See the temperature of each CPU core and the package, the GPU core and its hot spot, and your SSDs, with the minimum and maximum since you opened the app.
Each reading is labelled Normal, Warm, Hot or Critical, so you know at a glance whether something is wrong.
How temperatures work
On battery, Taskvane shows the whole laptop's power draw in watts and how long the charge will last at that rate. With admin rights it adds CPU and GPU package power.
It also shows battery health: how much charge your battery can still hold compared with when it was new.
About power readings
Processes are grouped under the app's real name, like "Google Chrome" rather than 25 copies of chrome.exe, with combined CPU, memory and disk.
Right-click to end a task or a whole process tree, change priority, open the file location or see details. Startup apps get their own page.
Process tools
Performance graphs for CPU, memory, every GPU, disk, network and power go back up to an hour. Hover anywhere to read the exact value at that moment.
Export the last hour as a CSV file when you need to prove a problem or compare runs.
Performance graphs
A monitor that slows your PC down defeats the point. With the window open, Taskvane uses about 0.4% of the CPU on a 2019 laptop.
It reads every process in a single Windows system call, the same source Task Manager uses, instead of opening each one. Hardware sensors run in a separate helper process, so a misbehaving driver can't freeze the window.
Task Manager is still great for services and per-app network use. Taskvane covers the hardware side it skips.
