Story

Many times CPU gets overloaded.We doesn't recognize the CPU stress and use the PC until it gets heated.It may cause damage to our system.

CPU feeling stress

CPU Stress Detector is used to avoid this problem.An LED is used to indicate the CPU stress.

If the CPU gets overloaded, a red LED turns on and gives the alert.If the CPU is cool, then a green LED is on.By these indications, we can get to know the stress levels of CPU.
