It is very quiet, somtimes the fan will be up for a while. Most times it is as silent as I expected. The hard drive does have some kind of ticking, but not bother me at all, since my last notebook is sony vaio grx550, in grx550, the hard driver is far more noisy, and this one is really quiet
The onlything bothered me at first is the lack of windows key, however I can solve it by software reassigning...the stick point in my view is not as convinient as a touchpad. but I usually use usb mouse. Anyway it is really nice for office work and light to carry.
The pitty is that x40 is only good for office work...no good for entertainment at all. The screen is Ok but not as goos as my old grx550, and it runs slow for multimedia software and games. I think the shared memory of 855gme and the low speed cpu are the reasons behind it. The 1.8 inch harddriver is in fact performing ok, 16M/s in sandra 2004......
Maybe I ask too much for an ultra portable pc.
Overall it is a nice one for me since I mainly use it for typing paper.
