Diagnose
Hot to the touch. Here is what the heat is costing.
No web page can read a temperature, and this one does not pretend to. It measures what the heat does to performance, which is the number that matters.
What the report tells you
Three figures, each with its reading.
Decay
%
The performance lost after the boost ends and the machine settles, not the early boost step. This is the heat's cost, measured rather than inferred from a warm palm rest.
Curve shape
slide / step
A slide is consistent with heat winning. A step is consistent with a power limit, which can feel like heat. The two need different fixes, and a sensor tool confirms which.
Saturation
s
On a deep run, how long the laptop took to reach its settled level. Short means a small cooler; long means a large one that eventually loses.
The diagnosis
The shape of the curve, read for your case.
01A steady slide
Consistent with a cooler that cannot shed the sustained wattage; a sensor tool confirms it. Dust, old paste, blocked intakes on a soft surface, or a design that was always marginal.
02A sawtooth
Consistent with fan control lagging the heat. Often a quiet mode; the performance mode usually flattens it at the cost of noise.
03A single step down
Consistent with a power limit closing the boost window rather than heat; comparing on mains in performance mode confirms it. A cooling pad will not move this curve.
Every class comes with a stated confidence and the measurement’s own noise floor. How the shape is read
Where a browser stops
What it cannot tell you.
- No degrees: the browser has no sensor. HWiNFO or the vendor's tool reads the temperature; this test reads the consequence.
- No fan speed: the sawtooth shape is the only view of the fan the test has.
- No verdict on safety: a laptop that slides is losing performance, not necessarily at risk. Firmware protects the chip.
Which run
Deep, 9 minutes.
Heat takes time to build. The deep run's three minutes reaches the settled level a warm laptop actually runs at.
All three kinds are free. The choice is on the set-up screen.
Questions
Asked in these words.
- Can a browser test measure laptop temperature?
- No, and any web page that shows a temperature is guessing. This test measures throughput over time; heat shows up as decay with a sliding shape. For the temperature itself use a monitoring tool with sensor access.
- My laptop is hot but the test says it held. Is that possible?
- Yes. A hot chassis with a curve that holds means the cooler is carrying the load; the heat is being moved, not accumulated. Warm is not the same as throttling.
- Does a cooling pad fix overheating?
- It helps a sliding curve, because a slide is consistent with the cooler being the limit, and more airflow raises its ceiling. It does nothing for a stepped curve, which is consistent with a power limit. Run before and after; the report compares them.
