I share your feelings

But in my experience without some airflow a bare heatsink can only help 3-4 degrees max. If the card it is in a box it does not matter at all...

I have 3 of these OPi ones and the last one is/will be my last...
OPi's: 3 Zero, 4 One, 1 Plus, 1 PC2, 1 cam
OPi on transit: 1 One, 1 2G-IOT, 1 2G IOT Touch LCD
3 RPi 3, 1 RPi 2, 3 RPi cam

Currently I'm using OPi One's. In my application(s) the temperature rises and I keep using a undervolted 5V 30z30z10 fan... Later I will work on some PWM...

Manufacturing cases is an issue thou...

This can also be useful if we can adapt

Only, that my primary reason I bought an OrangePi is, that I need something with no mechanical/moving parts.

This is a very unwelcome and surprising change which was not indicated anywhere before purchase. The previous version of the board runs happily on under 500mW with the SoC at 34C and I made an order of 10 boards with this in mind.

I have not had an opportunity to test power consumption yet, but even with the GPU, Wifi, Ethernet, and USB off, and the CPU and RAM set to minimum clock the new board is sitting at 55C. This makes these boards useless for the purpose they were purchased for.

Right. And Wifi is still as crappy as it can get. So, where's the improvement?
Since it is the same CPU as in the older revisions, maybe they are feeding to much voltage?
Someone mentioned that the new design apparently has some changes around the voltage controller.

Where's the schematic for the new design?

Any news yet when we can expect these for PCB v1.4?

I am sorry but my engineer said that there is so many components, the temperature is definitely would be higher.
