Got my OPI-Plus few days back and CPUs were constantly shutting down after heating up. I repurposed ...

Very nice. Have to add the simple case to mine. May try running without fan for a bit. I definitely don't work it very hard and getting tired of the noise. Already moved it from a 5V pin to a 3V3 pin and cut noise in half. Thanks everyone for nice pics.

When I ordered my OPI-PC I ordered THIS and THIS. I didn't know what I would need and figured I couldn't go wrong at the price.

This is the OPI-PC with standard Raspberry Pi heatsinks on the CPU and RAM.

Here it is with the fan suspended over the CPU with hardware from an old PC case and 2 rubber bands.

Here it is in a case made from a leftovers box with a vitamin bottle as a 'chimney' for the fan.

I have not done any formal temperature tests.

You can see above that the fan is connected to pins 4 and 6 on the GPIO. This is quick and easy but the fan runs whenever there is power to the unit. I plan to tack leads onto the power pins for the USB so the fan turns on and off with the power button.

With 35x35x25mm aluminium heatsink OPI PC (w/o case, loboris image, @1536Mhz) H3 temperature was less then 60C.(at 22C ambient)
Checked with cpufreq-ljt-stress-test and cpuburn-a7 in background.
