>What would happen if you added a second compressor loop with its cold side on the hot side of the first one? What if you added a third one? You've now got 3 stage cascade phase change(compressors cool stuff by compressing gas into a liquid, then letting it suck up thermal energy while decompressing/evaporating back into a gas elsewhere, i.e. phase change) cooling on one end, and a spectacularly inefficient heater on the other. Now wait a second... that's not just wrong, that's precisely the opposite of reality. If you have a heat pump, it must be more efficient than a simple heating element. If it at all cools the processor, by the simple laws of thermodynamics, it must heat the room more than any process which simply converts the work directly to room heat.
