It is a TEC controler so that it will keep the tempratures at exactly what you want. You could make it so that your cpu was exactly 5 deg cel to keep condensation off, but while underload, your temp would not change at all. I couldn't tell you priceing or anything of that sort, but it looks like a good idea.
