Which peltier?

[p0ntif]

I need suggestions as to which peltier to use for a project I am starting.

I want it to run around -10 to -20 celcius without any load, and I want it to be as small as possible. Does anyone know where I can find a peltier that runs those temperatures at a relatively low wattage that is tiny (about 1" X 1" or so). If not, can you suggest any that somewhat fill that description? Additionally, does anyone know of any peltiers that are 'odd-shaped' i.e. semi-circular, rectangular, etc. thanks!

what are you using it for? any peltier will get that cold with no load but to cool a cpu you need at least a 172watt and to get any real bennifit a 226w.

To run -C temps with pelts usually requires multiple (2 or more) 172/226 watt pelts on current cpus. TEC cooling isn't for the faint of heart, it involves a cold plate, the pelt(s), the hsf/waterblock, lots of anti-condensation foam around the socket, and finally, a dedicated psu. Go over to overclockers.com and ask about it, a lot of people have tried it there and most will tell you its's not worth the effort. For the money and time you're better off going phase-change.

You can get a mach i for around 400 now days used. Look into that maybe. I jaut picked up a Mack II. Cant wait to set it all up!
