    I downloaded Open Hardware Monitor to check the temperature of the machine because I was having some overheating issue with my HP8470p.

    I am not sure how does the app report the CPU temperature.

    Does the machine has a mechanics of temperature sensor built in and the software was reporting the actual temperature from the sensor? Or it just does some mathematic calculation based on the activities going thru the CPU?

    I have a cooler pad running when I do heavy duty processing. I believe the external fan forcing cool air into the machine would lower the temperature a bit. But if the app is based on calculation, the reported temperature would be the same with or without the fan because the fan is external, not part of the machine.

    Also, Open Hardware Monitor reported 100 degree C. What is the max. temperature that the machine can take?

    a lot less than 100c for sure.have you blown the dust out and replaced the heatsink compound?hw reports from the sensor.

    It's not uncommon for them to read really high values if the sensor isn't reading right. I'd try HWInfo, it's very detailed and tells you exactly what sensor it's reading and had better luck with its accuracy lately. CPU temp is generally measured as the "die" temp which is a sensor on the chip itself and then also a "socket" temp which is a sensor that resides within the CPU socket. The die, frequently called Tctl, is what you should go off of. Generally they're pretty accurate to real life temps but there is some calculation that goes into them to make it a smooth cooling curve. Generally you want to keep stuff under 80oC, preferably lower, esp on a desktop. It's not unusual for laptops to climb into the 80's. Socket temp you can usually disregard but if it's really high then usually means you're overvolting the CPU, not an issue unless you're overclocking.

    Depending on the processor, max temperature is 105°C, if it's a 3rd gen i5 or i7 mobile processor.

    I ordered a tube of thermal paste and will try to re-glue the heat dissipater (?) to the GPU and CPU.
    Is this a required process for CPU and GPU every so often. Does the video processing (encoding) that pushes the processing to 100% which generate heats makes this a necessity?
