Laptop Noise

is there any way to reduce the fan noise in a laptop?

I have changed fans and runs some fans at lower speed by using the 5v bus
for power in desktops.

any similar techniques with laptops?

thx, pjl

Due to being "battery powered", Laptops normally only increase fan speed
to prevent the CPU from frying.

understand. this one just turns it on and off, and it runs full speed about
80% of the time.

some laptops are really quiet when they run, what fan do they use?

agree. any theories on why w2k takes more power than xp? all things equal
to best of my ability, it just seems to take more power to run, which i have
no clue to explain.

Take a look at the CPU usage levels and background processes. While W2K
is NT5.0 and WinXP is 5.1 some changes were made to make XP more
"efficient". (I'm not refering to the eye-candy addition) But you may
also have different drivers and programs between the two installations
causing this.

Don't mess. Thermally, laptops are balanced on a wire. Reduced fan
speed increases heat.

Every once in a while, there's a bios upgrade, that controls the fans
better.
