If the laptop is overheating when the fan is going full speed, you have problems beyond just the speed/noise of the fan. Having a fully running fan shouldn't cause your machine to overheat, and in fact should do the opposite and cool your system down.

If you are wondering where your first post went, you hit the 'report' link, not the 'reply' link. You either coped your post prior to posting, or you retyped it perfectly -- typos and all
]]>Edit /etc/sensors.d/sensors.conf and look up your exact chipset. A few chipset names are similar, so make sure the one you are editing is yours. Add the line 'set fanX_div 4' near the start of your chipset config, replacing X with the number of CPU fans your system has.
How can one find the exact chipset name? The overall information spilled out by dmidecode is staggering.
Later Edit:
Accoding to http://en.gentoo-wiki.com/wiki/Lm_sensors#Configuration ,the chipset name should be in the sensors output.
