anarcat/stressant
Stressant is a simple yet complete stress-testing tool that forces a computer to perform a series of test using well-known Linux software in order to detect possible design or construction failures. Stressant builds on top of existing software and tries to cover most components of your system (currently disk, CPU and processor).

stressant --smart --disk --diskDevice /dev/sda --overwrite --no-network
Only test CPU:
stressant --cpuBurnTime 20m --no-network --no-disk
