Is ther a program that can testing my cooling supporter on my laptop duo core and what temp should duocore 1.73ghz run?

Answer:

Fans aren't really tested next to special software, but you can run a CPU intensive program and it should turn on and suck out the hot air. I believe it should be around 40 Celsius at idle and high during load, but it might be slightly different depending on your processor type (intel/amd) and the computer's design.
the tempurature should not walk much past 40 degree celcius
