I began switching to linux after seeing windows updates popping up every other day on my windows 2000 installation. I knew that one of them would end up breaking something. Kind of like the outlook "security update" that blocks opening nearly all attachments...
On my computer, the fans are controlled by something like this. I just used 4 2n2222's and used two parallel port lines, one with a 10k and the other with a 5k resistor, on each so the speed was variable. I'm thinking of adding some 74HC595 shift registers to get more outputs - these can be chained to get virtually as many outputs as you want. I also added some buttons to override the computer control, if necessary. The hardware's a mess but it works well with the software I wrote (the fan speed increases when the case temp rises or cpu usage increases.)

They patented the obvious ways to defeat their copy protection scheme, right?
