OCCT 9.1.2

OCCT is a stability checking utility that was developed back in 2003, and was constantly updated since. It permits you to entirely test your PC's stability, using four different tests: CPU:OCCT and CPU:Linpack aimed at examining the CPU, GPU:3D for the GPU strength, and Power Supply, a mix of CPU:Linpack and GPU:3D to completely load your Power Supply.

Each test can be used indefinitely, or for a determined amount of time. You can even add an idle period at the start or at the end of a test, to better understand how your PC's temperature ascent from an IDLE state to entirely loaded, and the other way round.

OCCT also integrates a monitoring engine, offering you full readings of the PC's inner temperatures, voltages, and fan acceleration, and shows them both in graphs in real time and at the end of a test. If you are concerned about strength with the real time graphs, don't: even if they are very light, just concealing the graph panel will stop them from refreshing.

OCCT even defends your PC from overheating or damage by adding alarms you can change for each sensor: once you go over (or under) the alarm amount for a voltage, temperature, or fan speed, the test will stop to conserve your computer.
