To fix the thermal issues of the CX31993, we must first look at what the silicon is designed to do. The chip integrates a digital audio interface, a high-performance DAC, and a headphone amplifier into a tiny package. Key Technical Parameters Up to 32-bit / 384kHz PCM.

According to user reviews, the CX31993 running warm is . The chip is designed to operate within a specific thermal range, and the metal casing acts as a heat sink. However, if the dongle is hot to the point of being uncomfortable or causing audio distortions, the "hot fix" steps (specifically using an impedance adapter or ensuring low-power idle) should be applied. To fix the thermal issues of the CX31993,
It is normal for high-performance portable DACs to generate heat because they draw significant power (often pulling Warning: Requires micro-soldering
The CX31993 is incredible if you manage its thermal envelope. For reference, its competitor—the ALC5686—runs 10°C cooler but has worse THD+N.
