A new app for finding out how hot your PS3 actually runs, and whether a repaste, a fan change or an overclock made any difference.

Live readouts for CPU and GPU temperature, fan duty and both RSX clocks, with a graph of the last 2 to 30 minutes.
Four load steps, from off to a full burn across the CPU, all six SPUs and the graphics chip.
Every run is saved to /dev_hdd0/tmp/thermal-bench/ as a spreadsheet-friendly file, written as it goes so even a lock-up leaves the data behind.
Your previous run is drawn behind the current one as a faded line, so the difference is visible while the test is still running.
Change the RSX core and memory clocks live with Select and the d-pad — no reboot. The clocks you started with are shown next to the current ones, and a change stays after you exit until the console reboots.
Switch between °C and °F with Start.
A safety cutoff at 88 °C drops the load and puts the clocks back. It also fires if the console refuses to report its temperature, so the test never keeps burning while flying blind.
The screen tells you when something is wrong rather than only the log: cutoff fired, run not being recorded, fan set to manual.
