I have been reading a lot of information about the temperature of the eeepc, people overclocking, people running fanless and people complaining about the temperatures and teh noise of the fan etc, it seemed that there were two groups, one with cold eeepcs and other with extremely hot eeepcs. Here my findings and experience:

I have a green 4GSurf.

The eeepc has 2 ways of cooling, one passive and active, the pasive is the metal bay under the keyboard, the active is a fan under the board where the cpu is located.

The range of temperatures for the fan running are:
.  - 54Celsius no active cooling
54C - 66C The fan is turned on in a quiet mode
67C - . The fan is turned on in "noisy" mode or fullpower.

Once the fan is turned on the temperature triggers are different:
- From noisy mode to quiet mode the trigger is around 58C
- From quiet mode to turn off is around 45C? I dont know this one as I have never been in this situation

With a room temperature of 22C and surfing in pages without a heavy flash load:
The normal temperature of the eeepc after 10 minutes is between 55C and 60C
The normal temperature of the eeepc after 1 hour is between 55C and 60C with peaks of 63 in periods of 10 seconds maximum and going under 60 strait away.

With a room temperature of 22C and doing heavy work (seing videos in youtube for instance) after 1 hour of using the eeepc it can reach to peaks of 64C but it seems very difficult to reach this mark.

With the eeepc overclocked at 900MHz and doing heavy work (for instance seing videos in youtube) the 65C mark is reached before the first minute, and the 67 mark (when the fan is turned on in full power)is reached before 2 minutes (having had the eeepc turned onn for 1 hour before the test). with the fan to full power it seems that is able to stop the temperature around the 68C not rising anymore

I hope this will solve some questions to people because I read some people saying that were reporting having normal temperatures well under 50C in normal conditions, something that scared me as my eeepc reaches the 60C in normal conditions without heavy work after one hour. Also I saw people saying that they would never allow their eeepc go higher than 65C in the overclocking test as it was dangerous, but now we can say that 65C in the eeepc is perfectly safe as the fan has a "full power" mode that is triggered at 68C and if they programmed that trigger is because they expected the eeepc to reach that temperature or even higher temperatures (for most of us we are yet in winter, lets see during the summer)

I hope this is useful for people like me that were worried to have the eeepc 10C hotter than normal laptops and what it seemed a "useless" fan, now I dont think it is so useless after seing it running in fullpower mode at 68C.

For people having the noisy fan problem I wonder if the problem is that their fan runs into fullpower at the 54 marc instead of the quiet mode, maybe it is a problem of the wiring of the fan?? a bios problem?

For people running fanless I would say that they should be carefull reaching the 68C and that the fan is not so useless when you heard it running in full power mode as it seems when it runs in quiet mode.

PD: My fan is not at all noisy in quiet mode, but it is loud enough to heard it at 2 oclock in the morning in a small room, but not loud enough to be heard in a library.

Can any of you confirm the triggers I put with their own experience? I have double checked my tests, I monitor the temperature with the gkrellm
