well, these are always great:

http://www.newegg.com/app/ViewProduct.asp?submit=manufactory&catalog=127&manufactory=1400&DEPA=1

they are thermo controlled fans. they are cheap too. $6 for a VERY nice fan. (ive used em before, they are quiet, and very good efficiency). the box has a rating of how fast they spin for how hot. you can always just insulate the sensor if you want it to go slower at higher temps. it just depends on where you put the temp probe.

that is actually a great idea. those fans are nearly silent, and big enough to cool a good-sized heatsink adequately. and for the price, cant go wrong. btw, the store (newegg.com), is VERY reliable. one of the best ive dealt with online. fast shipping and great prices.

Its probably cheaper to buy one from Farnell.com for Papst fans.
