Got my OPI-Plus few days back and CPUs were constantly shutting down after heating up. I repurposed a heatsink from an old AGP video card and also used the spring loaded nylon standoffs which came with it. This heatsink is optimum in size and covers SOC and both the RAMs. You can also use the heatsinks from an old motherboard, usually found on north or south bridge chips.
Used heaksink coumpond and held the heatsink down with a thick copper wire running between the standoffs. Also, drilled some holes in the case just on top of heatsink to aid better air flow. The case is homemade, made of plexiglass and some hex nuts.

I am getting range of 40C - 67C between idle and CPU stressed. Ambient room temperature is around 26C - 27C. I will keep monitoring this for few days, I dont want to add a fan as of now, but if the temperature is constantly in upper range, then I may have to make up my mind to add a small fan

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.
