Hi there,
First post, and I need some help! I'm Working on a pc project, and I'm going to watercool it with the help of some TEC's. My question is about a high end ATX power supply (1500w) and it's individual 12v rails. There are already some great audrino TEC controllers for this kind of project (http://www.arqtik.com/index.php/category/15-arqtik-controllers) , but my problem is they have a limitation with amperage. I believe I need about 20 amps (@12v) to accomplish my goal. My power supply has 25a rails, and the appropriate heat sinks to do the job. Is there any way to control individual rails (in my case two out of eight) with a audrino based controller like the one in the link? The guy who is building these has some really cool features built in, such as dew point. Any help in pointing me in the right direction would be greatly appreciated!!!
