I’m having apparent thermal cut offs on my DSD Dac and now my new BHK preamp. I am concerned about my shelving made of wood 3/4 thick.
I have 6 inches of open space above the DAC and 4.5 inches above the BHK.
SO I am thinking about buying quiet 4-6 inch fans to improve circulation. They are rated in dba with the quietest one I can find rated at 19 dba. They run either off AC or 5 volt USB power.
Anyone find a quieter fan or have other suggestions? I don’t need to move much air but would like rubber standoffs so I can lay the fans on top of the two PSA devices.
