too much condensation
the peltiers top surface can be as hot as 500 degrees while the bottom surface next to the processor can be as cool as 45 degrees major disadvantage is the drastic temperature difference which can cause condensation when the PC is turned off.
To optimize the efficiency of a Peltier cooler for maximum performance, you can improve heat dissipation by using efficient heat sinks, ensuring good thermal contact between the cooler and the heat source, and minimizing temperature differentials across the device. Additionally, using a power supply with the appropriate voltage and current ratings can help enhance the cooler's performance.

The Peltier's top surface can reach temperatures close to the ambient temperature of the heat sink it is attached to. The cooling capacity of the Peltier device depends on factors like the input power, efficiency, and thermal resistance of the system.
A Peltier fan uses the Peltier effect to regulate temperature in electronic devices. When an electric current flows through the Peltier device, it creates a temperature difference between its two sides. One side absorbs heat, while the other side releases it, helping to cool the device.
You can convert heat from your laptop into electricity using a Peltier Cooler, but I don't think you're going to get enough power to charge the laptop. A Peltier cooler is a solid-state device that is used in a lot of car refrigerators. If you put power to it in one polarity it gets cold; flip the polarity and it heats up. And if you heat the device it will generate electricity.

According to Wikipedia:"Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other side against the temperature gradient (from cold to hot), with consumption of electrical energy. Such an instrument is also called a Peltier device, Peltier diode, cooling diode, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). Because heating can be achieved more easily and economically by many other methods, Peltier devices are mostly used for cooling. However, when a single device is to be used for both heating and cooling, a Peltier device may be desirable. Simply connecting it to a DC voltage will cause one side to cool, while the other side warms. The effectiveness of the pump at moving the heat away from the cold side is dependent upon the amount of current provided and how well the heat can be removed from the hot side."A peltier cooler is not a thermopile nor a thermocouple and it does not rely on the seebeck effect.
Peltier tiles use the Peltier effect to generate electricity from temperature differences. When an electric current flows through the tiles, heat is absorbed on one side and released on the other, creating a temperature gradient. This temperature difference generates a voltage, which can be used to produce electricity.
One disadvantage of using an electromagnet is that it requires a continuous supply of electric current to maintain its magnetic field, which can be costly in terms of energy consumption. Additionally, electromagnets can generate heat, which may affect their efficiency and performance.
the only problem(disadvantage) is its heat properties i mean it needs a heat sink to transfer all its heat it gets heated very fast
becuase metal conducts heat
For heat loss to be an advantage to humans rather than a disadvantage, the heat lost must be equal to that produced.
