Update on the $30 30 amp PS:

Running warmer now ~85℉
The PS fan has sped up also. Warm air is blowing out.
Wires are ~82℉

The new fan is blowing 3x the warm air out.
Its like a little heater.
The cube surface temp is about the same as the PS.

I'm using an infrared temp instrument.

I'm going to wait till morning to set the clock to high.
I'm cautious. Don't want to burn my apt down.
