PC thermal & performance analysis
See what's limiting your PC — and exactly how to fix it.
Upload a HWiNFO or OCCT sensor log and SmartBench scores the run, finds what's holding it back, and tells you the one change that actually helps — a fan curve, an undervolt, a power limit, or an overclock. No spreadsheets, no guesswork.
Reads every sensor · works with HWiNFO & OCCT · free to use
Numbers in. Answers out.
SmartBench reads the raw sensor data most tools just dump in a graph, and turns it into something you can act on.
Tailored to your hardware
Save your build's parts and every reading is checked against your actual CPU, GPU, cooler, and fans — rated power, boost clocks, and throttle points included.
Any log, every sensor
Drop in a CSV from any benchmark, game, or stress test. SmartBench reads every temperature, clock, power, fan, and voltage, then computes min / avg / max / p95 and time over limits.
Advice, not just numbers
A health score plus prioritized findings that tell you what's thermal-, power-, or voltage-limited — and the single lever that will actually move the needle.
Compare & track
Stack a run against your last one — or a whole build versus a new one — to prove a change actually helped instead of guessing.
Four steps, then repeat
The whole loop — change one thing, measure, repeat — without leaving the browser.
- 1
Build your PC
Add your parts (and your fan curves, if you tune thermals). Takes a minute, makes the advice specific.
- 2
Capture a log
Run any load with HWiNFO64 logging to a CSV — a benchmark, a game, or just normal use. OCCT logs work too.
- 3
Upload it
Pick the build and what the run was for (CPU, GPU, thermals). SmartBench matches every sensor and discards the rest.
- 4
Tune & repeat
Apply one change, run the same test again, and SmartBench shows the before/after automatically.
