Blaze CPU Stress Test
Light up every core and see how much turbo your processor really has. Click the burner, watch the flame climb with the load, and read the CPU Boost figure Task Manager hides: the share of processor utility running past 100%.
Click the burner and every core you picked lights up.

About Blaze CPU Stress Test
Most load tools tell you the processor is at 100%. Blaze CPU Stress Test tells you what is happening above it.
Click the burner
The app is built around a gas burner. Click its head and the workers start, one per core you asked for, up to every logical processor the PC has. The flame climbs with the load and the ports in the burner head light up for the cores under test, each one brightening with the core behind it. Click again to stop. There is a Start Stress Test button too, for anyone who wants one.
The boost gauge
The gauge beside the burner reads CPU Boost. Windows reports processor utility on a scale that can pass 100%, and the share above 100 is the real turbo headroom your processor is finding. Task Manager clamps that figure at 100 and you never see it. This app opens its own counter, asks for the uncapped value, and shows it to two decimal places while the test runs.
A flat load
Each worker thread spins for 99 milliseconds of every 100 and rests for one. The load is steady rather than bursty, and no thread is pinned to a core, so Windows spreads the work the way it normally would.
What you see while it runs
The headline reads how many cores are burning and the total load. Under it, the elapsed time counts up and the boost figure sits beside it. A bar for every core shows where the work actually landed, and above them the app names your processor, how many cores it found, the performance and efficiency core split on a hybrid chip, and the base clock.
On a laptop
The battery row shows the charge and whether you are charging, plugged in or running on battery power. Turn on the safety stop and a test ends by itself once the charge falls under 20%. A test also ends when you stop it and when the window closes, so nothing is left burning behind you.
No account. No sign-in. Nothing leaves your PC unless you choose to send feedback. Dark by default, with light and match-Windows themes.
Built for Windows 11, and at home on Windows 10.
