Managing the heat rejection from a Peltier element requires a finned heat sink bonded to the hot side and a fan to force air across the heat sink, adding mechanical complexity and noise despite the common marketing claim that Peltier devices have 'no moving parts.'

Evidence Quote
“you need a finned heat sink bonded to the hot side to spread that heat out, and you'll also need a fan to force air across the heat sink... A fan and heat sink pair isn't complicated or expensive, but it means this is noisier than you might expect and, ya know, adds a moving part.”
