well this answers that.
For the normal task of web browsing the v2000z is pretty quiet and the fan is off mostly. But on warmer days it does turn on once every 20-30 minutes for a few seconds (typically for 20 seconds) and then stops. When the fan is running it is not loud at all, but I would not say it is whisper quiet either. The fan turns on when the CPU temperature reaches 55C and turns off when the temperature drops to 50C. While running with full load (at maximum speed and maximum load) the CPU fan turns on and off every 20-30 seconds. Not bad at all. It also looks like the fan has different speeds, but I'm not sure how much it varies.
I do not feel heat is a problem with this laptop. After prolonged use on warmer days it also gets warm, but never hot. One thing I observed is that the left palm area gets warmer after an hour or so. The hard drive temperatures are warmer than I would like. After a couple of hours HD temps climb to 48C, sometimes hitting 51-52C, if you're doing any disk intensive tasks. Still though, overall the v2000z pretty good in heat and noise department.
