Phononic HEX 2.0 Thermoelectric CPU Cooler Review

The Phononic HEX 2.0 Dashboard software can be downloaded from the site, and it runs without needing to be installed, which is nice. The software offers a status check at the top, where we see that the USB cable is detected, and we are good to go to address what controls are offered.


There is a cooling power meter shown at the bottom left, which changes as the TEC is cycled on and off, and the ability to choose from three TEC control profiles. Lastly, at the bottom right corner, we are offered a window that delivers 64 color options to use with the backlit logo built into the fan shroud.



To help explain the profiles, they use code that is set to look for certain metrics to be at a point to where the TEC is needed and then turned on. In Standard Mode, we saw the TEC turning on at 39 degrees of CPU temperature, not the core temperature. The cooling power meter jumps to three bars worth of power and continues to run until the CPU temperature reaches 37 degrees.


High Ambient Mode is used when you may not have climate control. This is set to make sure condensation is not an issue and the thermal range to power the TEC is raised. In this mode, we found the TEC to kick on at three-fifths power when the CPU reaches 42 degrees and turns back off at 40 degrees. The insane mode allows the TEC to receive full power, even though the meter is not showing that at this time. Without CPU heat to drive the switch that powers the TEC it will not run, but as long as the CPU draws more than 35W of power, the TEC will run, but there are conditions that need to be met to run this mode.


When the button is clicked to set Insane Mode, a warning pops up noting the ambient temperature should not be over 25 degrees, and humidity needs to be 50% or less. This is because with TEC cooling once the dew point of the room is reached, your TEC will condense like a glass of ice water on a hot summer day.
