What is idle CPU temperature for Fujitsu LifeBook T5010, T900 , T901

[Innuganti]

I am using the Fujitsu LifeBook T5010 and my brother is using Fujitsu LifeBook T900. One of my friends is having the Fujitsu LifeBook T900. For my Fujitsu LifeBook T5010, I am getting the idle temperature as 38 degree, my brother is getting 50 and my friend is getting 25. Can somebody please explain that why there is such a big difference in the temperature? What are the factors that affects the temperature of it. Please reply for this. I will be thankful to all the replies.

The difference in the temperature is because of the number of applications that three of you are running in your machine. If you are having more number of applications running on the system the there is no doubt that you will get higher temperature as compared to the system that is running less number of applications. This is one of the possible reason for this issue and for that reason you might be getting this issue.

Idle CPU temperature of the laptop at normal use should be around 40 degrees or +-10 degrees. If you are getting more than that then this is overheating problem and you must get it resolved as soon as possible as this might lead to some hardware failure.

Id you are getting the temperature about 35 degrees then there is no problem but if you are getting above that this is dangerous and can cause issue for you.
