Ealier today I assembled the DIY fan controller based on your instructions but I must have messed up somewhere because it's working backwards, that is, the fan increases in power as the temperature gets colder, any ideas about what I got wrong and how to fix it?

Are you sure you used an ntc thermistor instead of a ptc thermistor?

I'm not sure, I used a flat headed thermal sensor like the one depicted here it doesn't say if it is NTC or PTC. I suspect that the termal sensor is the problem and I am looking for another one but I am having a hard time finding thermistors, radio shack doesn't have them, and I can't find them online except in huge bulk orders from suppliers where I have to request a quote for my order, any idea where I can buy one?

I found an online electronics store with reasonable prices and shipping charges for individual parts, are these the correct parts?:
