BRO! It's a fact, not an assertion. A peltier acts EXACTLY the same as a compressor based system. If the heat load is to high for the peltier, it WILL overheat and fry your cpu.
Like I said a peltier does NOT GENERATE COLDNESS. It MOVES HEAT. The wattage rating specifies how much heat can be MOVED through the device before it overwhelms it.
A peltier also creates heat as the byproduct of moving heat. so the peltir may move 50 watts but to mave that 50 watts it creates XX amount of heat. The problem is that once the heat load overwhelms the peltier, then all you have is more heat being generated.
Oh well, your going to try it anyway but first go here
