hmm, so no way around this? I remember people asking why I was using tip122 and not mosfets. I thought it had something to do with efficiency (and my mind read that as less heat) rather than anything else. but I guess I was wrong. oh well.
so caveat emptor would be - if you have loads of old scrap computers lying around build linisteppers as you'll need all those peltiers (and maybe even vapochill) later on. otherwise stick to choppers?
