Just to build on your comment so other hobbyists don't get the wrong idea, Peltier modules are significantly less efficient than compressor-based coolers. To the tune of 30% or more efficiency drop depending on ambient conditions and your heatsink setup. It's also important to note that the overall setup for a Peltier system ends up being a lot bulkier than most people expect when they start. You need a really beefy hot side radiator and fan to get any significant cooling potential out of the system - think large CPU heatsink + fan size and you're close. If it's humid you'll also have to deal with condensation on the cold side so you don't accidentally get water dripping on your electronics.
